Mysterious childhood illness associated with COVID-19 being investigated in Colorado – FOX 31 Denver

May 20th, 2020

DENVER (KDVR) — Three children at Children’s Hospital Colorado are now being investigated for a rare – but potentially deadly – new illness that’s associated with COVID-19.

Doctors first noticed Multisystem Inflammatory Syndrome in Children (MIS-C) in Europe and now there are at least 150 cases in the United States. The illness appears to have killed at least four children.

“Because this is a new and emerging syndrome, there is still a lot we don’t know about MIS-C,” Gov. Jared Polis said Wednesday.

Many of the children, who are usually 5 to 15 years old, with MIS-C have COVID-19 antibodies, which show they have probably been exposed to or had the coronavirus. The new syndrome’s symptoms have been known to show up about a month after children had the coronavirus.

“I know that there are a lot of parents who are afraid and anxious when it comes to thinking about this new SARS coronavirus,” said Dr. Sam Dominguez, an infectious disease expert at Children’s Hospital Colorado. He also said the syndrome should not cause parents to panic, but they should watch for it.

MIS-C Symptoms

  • High fever that often lasts for several days
  • Severe stomach pain
  • Vomiting
  • Diarrhea
  • Low blood pressure

Some children with MIS-C also show symptoms of Kawasaki Disease. They include rash, red tongue, dry and cracked lips, and artery inflammation.

Almost none of the children with the syndrome had breathing issues, a common symptom of the coronavirus.

“This suggests that what we’re seeing in these children is a post-infectious or inflammatory response to the virus, as opposed to direct ongoing damage from the virus itself,” Dominguez said.

Polis said the state did not have enough information about MIS-C to know if it could affect in-person learning in the fall.

In a separate update Wednesday, the Colorado School of Public Health said it estimates that as many as 167,000 Coloradans are suspected of already having had COVID-19. That’s more than seven times higher the number of current documented cases (22,797).

Jill Hunsaker Ryan, the executive director of the Colorado Department of Public Health and Environment, said, “If you think about that, we are really still just at the beginning of this epidemic.”

State health officials saying a slow, gradual reopening of businesses is key to continuing the flattening of the curve.

Provincial and federal officials encourage masks in close quarters – CTV News

May 20th, 2020

VANCOUVER — They are becoming a more common sight around Metro Vancouver, and now Canada’s top doctor and B.C.’s premier are both encouraging the use of non-medical masks when it’s not possible to keep your distance from others.

While she initially wouldn’t endorse their use, Dr. Theresa Tam has changed her position on promoting fabric, non-medical masks for use by the general public. But, she emphasizes, they are an added preventative measure, not a replacement for physical distancing or frequent hand-washing.

“If you can’t predict whether you can maintain that two-metre distance, then it’s recommended that you wear the non-medical mask or facial covering,” said Tam. “From our perspective, it is an added layer of protection, it is for you to protect others. So if two people are wearing masks, I am protecting you and you’re protecting me.”

The premier encouraged British Columbians to follow the advice hours after Prime Minister Justin Trudeau walked into the House of Commons wearing a mask of his own.

“I’ve got about a half a dozen of them now, trying to find the right look for me,” said John Horgan at his weekly COVID-19 briefing in Victoria. “I’ll certainly be wearing a mask if I can’t physical distance and I encourage all other British Columbians to do the same thing. I expect if you’re hopping on a SkyTrain or catching a bus …you’re going to see increasing numbers of people who are wearing masks and PPE as they move around our urban centres.”

TransLink is urging passengers to wear masks as a growing number of people return to work under phase two of the province’s reopening plan. Masks are also a cornerstone of WorkSafeBC’s guidelines for workers who can’t keep their distance from each other or customers.

“The message to Canadians must remain all of those previous measures, with this as an added layer of protection,” said Tam.

Doctors approve of new policy

The change in position is welcome news to physicians who’ve been advocating for government endorsement of non-medical masks under the #masks4canada hashtag.

“I’m glad they have changed the tone first from ‘not recommended’ to ‘suggested’ and now to ‘recommended.’” said Dr. Jennifer Kwan, a family physician in Burlington, Ontario. “That’s a big shift in tone, which is great because I really do believe that masks are going to be a key factor in addition to other factors such as sustained distancing measures, robust tracing programs and testing.”

She calls it a good balance between preventing new COVID-19 transmission while being able to restart the economy and wants even clearer public messaging about when to wear masks, how to wear and dispose of them, and recommended designs.

“There’s still a lot of information the public is looking for,” said Kwan. “People are doing a great job learning how to hand-wash, I’m sure everyone can also learn how to use a mask properly.”

Demand surging for masks that don’t look “scary”

While the idea of wearing a mask is foreign and unwelcome for some, local companies have been inundated with orders for fabric masks of various designs and qualities suited to their needs and personal style.

Granville Island mainstay Make – which specializes in custom t-shirts, pillows and home décor – started making masks just two weeks ago, but has been flooded with orders ever since.

“We’d had to lay off most of our production staff, but now we’re bringing everyone back to get on our mask-printing program,” said owner Stacy Hall.

The company has been pumping out hundreds of polyester masks with pockets for replaceable filters in eccentric patterns, such as cartoon pineapples and dinosaurs, plus photo-realistic moustaches and clever mottos.

“We’ve had a lot of notes on the orders, people thanking us for something they can feel comfortable wearing, that their kids will wear without making it seem like it’s scary or something fearful,” she said. “It’s funny: once you start wearing it, you start feeling weird when you’re not wearing it.”

Reopening guidance for churches delayed after White House and CDC disagree – msnNOW

May 20th, 2020

Guidance for reopening houses of worship amid the coronavirus pandemic has been put on hold after a battle between the Centers for Disease Control and Prevention and the White House, which was resistant to putting limits on religious institutions, according to administration officials.

The CDC this week issued a detailed road map for reopening schools, child-care facilities, restaurants and mass transit. On Tuesday night, the agency issued additional guidance in the form of “health considerations” for summer camps, including overnight camps, and youth sports organizations and colleges.

But there are currently no plans to issue guidance for religious institutions, according to three administration officials who spoke on the condition of anonymity to discuss policy decisions.

White House spokesman Judd Deere said President Trump and “all Americans want to see their churches safely open again. Not only is it good for the community, it’s their right under the Constitution to worship freely without government intrusion. The Trump administration will always protect that right and continue to partner with states to ensure congregations are properly protected as restrictions are responsibly eased.”

A coronavirus outbreak at an Arkansas church that killed three and infected dozens, as well as recent church closures in states at the forefront of reopening efforts, are already challenging the wisdom of the CDC not issuing guidance, experts said.

The Arkansas outbreak, detailed in a CDC report this week, began after a pastor at the church and his wife attended church events over six days in early March and spread the virus to others. At least 34 of 92 attendees at church events became infected, including the three who died, all over the age of 65. An additional 26 infections and one death in the community were probably linked to contact with people infected at the church events, according to the report.

Public health experts said the lack of reopening guidance for religious institutions puts some of the most vulnerable at risk for contracting covid-19, the disease caused by the novel coronavirus.

Worshipers tend to be older than the population at large and are among the most at risk from the virus, said Tara Smith, a professor of epidemiology at Kent State University.

“You’re talking about that group that is really vulnerable to this virus, and those are the ones you don’t have guidelines for and that you need to protect,” she said.

Smith is helping a Cleveland-area church navigate the safest way to reopen. She and a graduate student have gone over every aspect of the church service, from “what the priests are doing, to getting people into the church, to taking the host,” she said.

But “it should not be our responsibility” to guide the church if there are existing federal recommendations, Smith said. Any guidelines would be voluntary and intended to “keep people safe,” she said. “You think that would be the responsibility of the government. Churches could choose what to implement. . . . It just is really frustrating to me that these have not been released.”

CDC draft guidance on houses of worship was the subject of much internal debate at the White House last month. Some aides did not want any guidance for religious institutions. Others thought recommendations were too restrictive.

In the end, the decision to hold back reopening guidance for religious institutions came from some White House and coronavirus task force officials who did not want to alienate the faithful and believed that some of the proposals, such as limits on hymnals, the size of choirs or the passing of collection plates, were too restrictive, according to two administration officials.

Trump and Vice President Pence have maintained close ties to conservative religious leaders during the shutdown, scheduling private calls and asking for support as they try to reopen the nation, the officials said.

Officials in Pence’s office, the Office of Management and Budget and the Domestic Policy Council raised concerns about the guidelines for religious institutions, the officials said.

There were conversations about scaling back the guidelines, but after weeks of discussion, they were left out entirely, one of these officials said. At one point, officials discussed various religious groups and even called pastors and other religious leaders to see if they could shape the guidelines in accordance with “faith traditions,” according to one senior administration official.

A draft CDC document that detailed reopening guidelines recommended that faith communities consider temporarily limiting community sharing of prayer books, hymnals and other worship materials; consider using a stationary collection box, the mail or electronic payment instead of shared collection trays or baskets; and avoid or consider suspending choir or musical ensembles during services.

About a third of Americans — 31 percent — attend religious services at least once a week, the Pew Research Center reported last fall, down from 37 percent a decade earlier.

Nancy Davidge, spokeswoman for the Episcopal Church, did not have immediate comment about the decision to hold back reopening guidance for congregations, or whether the denomination had lobbied the White House.

Chieko T. Noguchi, spokeswoman for the U.S. Conference of Catholic Bishops, said the prelates have not discussed the CDC guidelines’ omission of churches. Asked whether the bishops had advocated a position on the guidelines with the White House, Noguchi declined to comment. The Catholic Church is the country’s largest faith group.

Other denominations are offering general suggestions to congregations about reopening. The Southern Baptist Convention, the country’s second-largest faith group, issued a checklist May 7 through its public policy arm, the Ethics and Religious Liberty Commission. Item No. 1: “Identify reliable, local sources of information. . . . Choices must be made based on objective data, not subjective impressions.”

Megan Fox stars in Machine Gun Kelly’s new ‘Bloody Valentine’ music video – Fox News

May 20th, 2020

Megan Fox is the star of Machine Gun Kelly‘s new “Bloody Valentine” music video.

The video, which was released on Wednesday, first sees Fox, 34, waking up next to Kelly — real name Colson Baker — before she puts pink duct tape over his mouth.

Then, throughout the three-minute video, Fox lip-syncs the lyrics to the song, rocks out on Kelly’s guitar, and much more, all while sporting multiple outfit changes.

BRIAN AUSTIN GREEN SHARES MESSAGE ABOUT BEING ‘BORED’, ‘SMOTHERED’ AMID MEGAN FOX SPLIT RUMORS

According to Page Six, a press release describe the video as an “affectionate twisted love story” between the two co-stars as Fox takes “full control of their fictional romance.”

The music video’s premiere comes two days after Brian Austin Green confirmed rumors he and Fox had split after almost 10 years of marriage.

BRIAN AUSTIN GREEN, MEGAN FOX SPLIT AFTER ALMOST 10 YEARS OF MARRIAGE, ACTOR CONFIRMS: I’LL ‘ALWAYS LOVE HER’

“Neither one of us did anything to each other,” Green, 46, said on his podcast, “…with Brian Austin Green” in an episode titled “Context” on Monday.

He continued: “She’s always been honest with me. I’ve always been honest with her. We’ve had an amazing relationship, and I will always love her. And I know she will always love me and I know as far as a family what we’ve built is really cool and really special.”

MARY-KATE OLSEN WANTED CHILDREN WITH OLIVIER SARKOZY BEFORE DIVORCE, SOURCE CLAIMS

The two began dating in 2004 and wed in 2010. Their relationship had been subject to split rumors before with Fox filing for divorce in 2015. The pair reconciled before the birth of their third child, Journey, now 3. They also share sons, Noah, 7, and Bodhi, 6.

In his podcast on Monday, the “Beverly Hills, 90210” alum also spoke about Fox and Kelly, 30, since photos of the two had recently surfaced, as did pictures of Green without his wedding ring.

Green said that Fox and Kelly are “friends at this point.”

“I trust her judgment, she’s always had really good judgment,” the actor said. “I don’t want people to think that her [sic] or he are villains or I was a victim in any way with any of this because I wasn’t. This isn’t something new for us. This is something new for people to experience and hear about in the press.”

Monkey trials at Harvard Medical School show promising vaccine results – CBS News

May 20th, 2020

Researchers at Harvard Medical School revealed stunning news on Wednesday, after they immunized 25 rhesus monkeys using DNA vaccines. 

“We showed that vaccines induce antibodies, and the vaccinated animals are protected either partially or fully,” he said. “But we also show that the levels of antibodies correlate with how good the protection is.” 

Dr. Dan Barouch, the lead author on the study, called the results a breakthrough. 

Researchers took the DNA of one of the coronavirus’ proteins and inserted it into plasmid DNA vaccines. These vaccines helped the monkeys develop higher levels of antibodies, which lowered the level of the virus following exposure. 

Researchers say eight of the monkeys who were exposed to the virus had no detectable trace of it, while the rest had very low levels of it.

When asked if he was optimistic that human trials would yield similar results, Barouch said that “while data from humans will require rigorous clinical trials, these data in an animal model increases our optimism that the development of a vaccine for humans will be possible.” 

Barouch is unsure, however, how long immunity from the virus will last. These studies did not address that issue, but he called it an “important question.”

Canada waited too long to close borders: Canada’s top doc – Toronto Sun

May 20th, 2020

Canada’s top doc admits authorities were slow to act in closing the borders in response to COVID-19.

Dr. Theresa Tam, Canada’s chief public health officer, said that quicker action could have been taken in responding to the global pandemic.

“The virus itself (was) travelling across the world very fast,” she told the standing Commons committee on health on Monday.

Noting that the virus’ epicentre was in China early in the pandemic, it wasn’t until cases started appearing in Europe and the United States that she says sparked real concern in public health circles over it spreading to Canada.

“At that time, because of a very few cases, we were doing incremental measures.”

Critics have argued that Canada’s reaction to COVID-19 was haphazardly slow, full of contradictory messaging and following the lead of both the World Health Organization and the Chinese government. China has come under fire for allegedly downplaying the dangers while the rest of the world scrambled to contain its spread.

On March 5, Prime Minister Justin Trudeau defended the decision to keep the borders open, dismissing calls to close them as “knee-jerk reactions” that were not required to keep people safe.

Two days after the U.S. declared a national emergency on March 13, Health Minister Patty Hajdu criticized calls to close the border, calling such measures “ineffective” against a global pandemic.

“Border measures are highly ineffective and, in some cases, can create harm,” she insisted, repeating her prior claims that closing borders could actually harm attempts to mitigate the spread.

Trudeau also said on March 13 that Canada was effectively managing coronavirus without closing borders.

Days later, Canada did an about-face and closed the borders, banning all foreign nationals for all but essential travel.

When asked by Bloc Quebecois MP Luc Theriault if Tam should’ve acted sooner, she said she wouldn’t have second-guessed policy makers advising against a shutdown.

Interrupted by Theriault who accused her of dodging his question, Tam relented.

“Could we have done it faster? Possibly,” she said.

“That is definitely something that could have happened faster.”

Saying the virus was travelling in “invisible ways,” Tam said a lot happened very quickly between March 13-18.

“In hindsight, yes, I think people could act faster and maybe in the future we would take different decisions and that remains to be looked at in lessons learned.”

BUG IN THE SYSTEM: Canada’s COVID-19 response

While debate rages on when COVID-19 first emerged, Chinese government data suggests patient zero was a 55-year-old man from China’s Hubei province, diagnosed Nov. 17.

Hubei’s capital city Wuhan proved the pandemic’s epicentre, with 79,112 reported infections and 5,912 deaths — although actual figures may be much higher.

During the week of Dec. 15, Wuhan’s medical community became concerned about exponential increases of the mysterious illness, particularly after health-care workers at two separate hospitals fell ill Dec. 25.

By late December, Chinese social media platforms began censoring mentions of Wuhan-related pneumonia online — including references to Dr. Li Wenliang, the hospital physician publicly admonished by government officials as a “rumourmonger” for sounding the alarm on Dec. 30, drawing parallels with SARS.

Li died Feb. 7 after contracting the disease from a patient.

Airports in South Korea, Japan and Taiwan had started quarantining Chinese travellers by Dec. 31, with Taiwanese officials boarding flights seeking symptomatic passengers.

China first contacted the World Health Organization (WHO) about the outbreak on Jan. 5.

On Jan. 7, Dr. Theresa Tam — Canada’s chief public health officer — said there’s “no evidence” of person-to-person spread, and called it a “positive sign” that no health-care workers had fallen ill.

The United States began screening travellers from Wuhan on Jan. 17.

On Jan. 19, Health Minister Patty Hajdu said “no clear evidence” existed of person-to-person spread.

Canada reported its first COVID-19 case Jan. 25, and its first death March 9.

On Jan. 29, officials responded to Canada’s outbreak by admonishing “stigmatizing comments” made online against Chinese-Canadians.

The WHO declared coronavirus a global emergency on Jan. 30, and a pandemic March 11.

On March 12, Ontario ordered all schools to close. On March 13, the U.S. closed its borders.

Canada did an about-face, closing its borders on March 16. The federal government banned ng foreign nationals on March 18, and restricted international flights to just four Canadian airports.

Ontario declared state of emergency on March 17, followed by Toronto on March 21.

On March 25, Canada imposes mandatory self-isolation for those coming into Canada.

Coronavirus hot spots erupt across the country; experts warn of second wave in South – The Washington Post

May 20th, 2020

The model, developed by ­PolicyLab at Children’s Hospital of Philadelphia and updated Wednesday with new data, suggests that most communities in the United States should be able to avoid a second spike in the near term if residents are careful to maintain social distancing even as businesses open up and restrictions are eased.

But the risk for resurgence is high in some parts of the country, especially in places where cases are already rising fast, including the counties of Crawford, Iowa; Colfax, Neb.; and Texas, Okla. and the city of Richmond. Since May 3, Crawford County’s caseload has risen by 750 percent, and Colfax County’s has increased 1,390 percent, according to state data compiled by The Washington Post.

This is an anxious moment for the nation as people emerge from shutdowns and communities try to reinvigorate economic activity. Scientists and public health experts are monitoring rates of infections and hospitalizations, but it is difficult to forecast during this transitional period because models struggle to capture how people actually behave, including adherence to social distancing and hand-washing practices.

There are preliminary signs, however, that hot spots — new clusters of coronavirus spread — could soon flare across parts of the South and Midwest.

“As communities reopen, we’re starting to detect evidence of resurgence in cases in places that have overreached a bit,” said David Rubin, director of PolicyLab.

Researchers at the University of Texas Southwestern Medical Center said last week that cases in the Dallas-Fort Worth metropolitan area could spike this summer, with a tripling of daily active cases of covid-19, the disease the novel coronavirus causes, if there is a significant easing of mitigation efforts. And PolicyLab projects that in the next month, Harris County, which includes Houston, will go from a couple hundred cases a day to more than 2,000.

The overall national picture remains ambiguous: The daily death toll from covid-19 is dropping, but increased activity and travel in a population that remains susceptible to infection means the coronavirus has new opportunities to spread.

Anthony S. Fauci, director of the National Institute for Allergy and Infectious Diseases, said Wednesday he has “no doubt” there will be new waves of cases.

“The virus is not going to disappear,” he said in an interview with The Washington Post. “It’s a highly transmissible virus. At any given time, it’s some place or another. As long as that’s the case, there’s a risk of resurgence.”

He said the country has time now to prepare for new caseloads, which could mount considerably in the fall.

A presentation prepared by the Department of Health and Human Services and the Federal Emergency Management Agency — and reviewed by The Post — suggests new waves could be steep enough in some places to overwhelm ventilator capacity.

For instance, the data indicates that only 866 ventilators are in use in Georgia, which has pursued one of the most aggressive reopening plans. But the state’s supply of 2,853 ventilators could be outstripped as soon as the end of the month by the projected number required for covid-19 patients, according to the federal modeling. States from Arizona to Colorado to Tennessee could face similar shortages, according to the projections.

An “ensemble” model that incorporates 20 leading pandemic models, developed by biostatistician Nicholas Reich of the University of Massachusetts at Amherst, shows a gradual decline in projected covid-19 deaths over the next four weeks, from about 9,000 this week to 4,000 in the second week of June. His model shows that by mid-June, the United States should expect to reach 113,000 deaths.

But Reich said Wednesday that this is a particularly difficult phase of the pandemic to capture in models because of uncertainty about how people will behave as restrictions are lifted. “There’s so much complexity and so much that could change,” Reich said.

Some communities seem to be abiding better by social distancing, Rubin said. They include Denver, Colorado Springs, Columbus, Ohio, and the Research Triangle of North Carolina, all of which look good in the new forecast.

But South Florida, which has the bulk of that state’s cases, looks worrisome in the four-week projection, Rubin said.

“That Southeast coast, they’re just starting to open up and relax. It’s a densely crowded area. There’s a lot of tinder down there,” he said.

Alabama will probably experience a steep increase in cases in nearly every county over the next month, according to the PolicyLab model.

State Health Officer Scott Harris said this week that Alabama’s numbers were “not as good as we could hope for.” The state began easing its stay-at-home order and other restrictions this month. Gov. Kay Ivey (R), who has allowed restaurants, bars, retail businesses, churches, gyms and salons to reopen, is expected to outline further steps this week.

In a news conference Wednesday, Montgomery Mayor Steven Reed said the city is facing a shortage of intensive care beds and being forced to divert patients to Birmingham. “They’re at a capacity that is not sustainable,” he said. “Our health-care system is maxed out.”

In upstate Monroe County, N.Y., home to the city of Rochester, hospitalizations of covid-19 patients have risen by about 70 percent over the past 10 days and 18 percent since reopening began on Friday. PolicyLab projects that cases in Monroe County will rise through the end of May before falling precipitously through mid-June.

Michael D. Mendoza, Monroe County’s public health commissioner, told reporters Tuesday that he believed hospitalizations have risen in large part because the county dramatically increased testing in May and is doing more testing in nursing homes and in hospitals. The number of covid-19 patients in intensive care and on ventilators has “remained relatively stable,” he said.

In Texas, there has been an outbreak of cases in El Paso and in meatpacking plants in the Panhandle. The rate of positives in coronavirus tests has gone down as the number of tests has increased, and hospitalization rates are holding steady. Gov. Greg Abbott (R) has sent “surge response teams” to places where there are spikes in infections. But the number of daily active cases is still rising in some parts of the state. Dallas and nearby Tarrant County, home to Fort Worth, each had its highest single-day death toll Tuesday.

Umair Shah, executive director of Harris County Public Health, said he has seen “slight upticks” but not “a significant increase thus far” in cases. He is concerned, however, about the state’s reopening.

“There’s mixed messages from the federal, state and local levels,” Shah said. “It’s summer, it’s 90 degrees right now outside — for people to start getting complacent and feel, ‘Oh, the virus is yesterday’s news’ . . . we have that concern.”

Lauren Ancel Meyers, who directs the Covid-19 Modeling Consortium at the University of Texas at Austin, said her group looks at cellphone data.

“It’s telling us the same thing we see when we look out our windows,” Meyers said. “We are seeing a big change in people’s mobility.”

The increased activity so far has not led to an increase in hospitalizations.

“If the changes in behavior that started in May really did accelerate transmission, we will begin to see that in the case data, the hospitalization data, the death data very soon,” she said.

One fundamental problem for scientists is that the virus does not reveal its presence readily. There is a lag in data. On average, it takes about five days for a person infected with the coronavirus to develop symptoms. That incubation period can be even longer — up to 14 days. Then there is another lag before a symptomatic person gets tested and gets the results or perhaps needs hospitalization.

“We’re looking at potentially a month or two later that we’re going to see the impact” of the reopening, said Leana Wen, the former Baltimore health commissioner. “You have not seen the impact of reopening yet. I think there’s going to be a very significant lag.”

Arelis R. Hernandez in San Antonio, Cleve R. Wootson Jr. in Tampa and William Wan in Washington contributed to this report.
