Q: Is one day isolation sufficient to stop forward transmission of COVID-19?
A: People with COVID-19 could potentially transmit it to others well beyond a day after developing symptoms or testing positive. New guidance from the CDC advises people to isolate until they have been fever-free and with symptoms improving for at least 24 hours, and then take precautions for five days, which covers the period when “most people are still infectious.”
Long COVID is a collection of health problems caused by COVID-19 that remain or appear following the initial infection. It is implausible that face masks cause long COVID, contrary to claims made online. Mask use can temporarily cause discomfort, but physiological effects are not biologically meaningful.
People online are touting the results of a Cochrane review to incorrectly claim that it shows masks “don’t work” against the coronavirus. But the primary conclusion of the review is that it’s uncertain from randomized controlled trials whether mask interventions in the community help slow the spread of respiratory illnesses.
FactCheck.org Science Editor Jessica McDonald fielded questions about second COVID-19 booster shots and the possible return of Philadelphia’s mask mandate in a recent interview that aired on several of that city’s iHeartRadio stations.
An increase in pandemic restrictions in Germany sparked a protest at a market, where a man dressed as Santa Claus was briefly detained. Online posts falsely claimed he was arrested for not wearing a mask. But police said he was detained for participating in an unregistered protest.
Citing new data on the delta variant, the Centers for Disease Control and Prevention recommended that fully vaccinated people wear face masks indoors in some parts of the country.
Health and Human Services Secretary Alex Azar says President Trump has been “clear” in calling for the public to “wear face coverings when you can’t social distance.” The official messaging from the White House has been clear. The president’s statements have been anything but.
