For months, scientists and public health experts have warned of mounting evidence that the novel coronavirus is airborne, transmitted through tiny droplets called aerosols that linger in the air much longer than the larger globs that come from coughing or sneezing.
Now, the Centers for Disease Control and Prevention agrees. The CDC recently changed its official guidance to note that aerosols are “thought to be the main way the virus spreads” and to warn that badly ventilated indoor spaces are particularly dangerous.“
There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes),” the agency stated. “In general, indoor environments without good ventilation increase this risk.”
The health department’s top communications official is taking a medical leave, three days after urging President Trump’s supporters to prepare for an armed insurrection and accusing government scientists of “sedition,” the agency announced Wednesday.
Michael Caputo, assistant secretary for public affairs at the Department of Health and Human Services, leveled the accusations and promoted other conspiracy theories in a Facebook Live event on Sunday.HHS said in a statement released early afternoon that Caputo would be on leave for the next 60 days to “focus on his health and the well-being of his family.” That means he will be gone until after the Nov. 3 election.
The agency also said that Paul Alexander, a top aide to Caputo, would be leaving the agency permanently. Alexander came under scrutiny in recent weeks for his efforts to exert control over the messages coming from scientists and top health officials, including the content of weekly science reports from the Centers for Disease Control and Prevention, to make them conform to the president’s assertions that the virus is under control.
A Facebook comment argued that mail-in ballots “will lead to fraud for this election,” while an Instagram comment amplified the erroneous claim that 28 million ballots went missing in the past four elections.
The messages have been emanating in recent months from the accounts of young people in Arizona seemingly expressing their own views — standing up for President Trump in a battleground state and echoing talking points from his reelection campaign.
Far from representing a genuine social media groundswell, however, the posts are the product of a sprawling yet secretive campaign that experts say evades the guardrails put in place by social media companies to limit online disinformation of the sort used by Russia during the 2016 campaign.
The health department’s top spokesperson Michael Caputo called an emergency staff meeting on Tuesday to apologize for drawing negative attention to the Trump administration’s health care strategy and signaled that he might be soon departing his role, according to five people with knowledge of the meeting.
The departure of Caputo, who has closely controlled the health agencies’ dissemination of information about coronavirus, would be a blow to the Trump administration’s efforts to promote a possible vaccine, if one is approved in the fall.
TORONTO/CHICAGO (Reuters) – High-profile COVID-19 vaccines developed in Russia and China share a potential shortcoming: They are based on a common cold virus that many people have been exposed to, potentially limiting their effectiveness, some experts say.
CanSino Biologics’ vaccine, approved for military use in China, is a modified form of adenovirus type 5, or Ad5. The company is in talks to get emergency approval in several countries before completing large-scale trials, the Wall Street Journal reported last week.
A vaccine developed by Moscow’s Gamaleya Institute, approved in Russia earlier this month despite limited testing, is based on Ad5 and a second less common adenovirus.
