First we were told face masks weren’t helpful in reducing the spread of the coronavirus because they would cause us to touch our face more and then spread the disease to others. Then we were told to wear the masks to save lives and reopen the economy.
Now the Centers for Disease Control and Prevention warns that face masks with vents or valves don’t reduce the spread of the virus, as those additions that allow the user to breathe easier can deposit more “expelled respiratory droplets that can reach others.” In guidance updated late last week, the CDC added a warning about face masks with exhalation valves or vents.
“The purpose of masks is to keep respiratory droplets from reaching others to aid with source control. However, masks with one-way valves or vents allow air to be exhaled through a hole in the material, which can result in expelled respiratory droplets that can reach others. This type of mask does not prevent the person wearing the mask from transmitting COVID-19 to others. Therefore, CDC does not recommend using masks for source control if they have an exhalation valve or vent,” the CDC warned (emphasis original).


Since the start of the pandemic, physicians have used hydroxychloroquine to treat symptomatic COVID-19 infections, as well as for prophylaxis. Initial results were mixed as indications and doses were explored to maximize outcomes and minimize risks. What emerged was that hydroxychloroquine appeared to work best when coupled with azithromycin. In fact, it was the President of the United States who recommended to you publicly at the beginning of the pandemic, in early March, that you should consider early treatment with hydroxychloroquine and a “Z-Pack.” Additional studies showed that patients did not seem to benefit when COVID-19 infections were treated with hydroxychloroquine late in the course of the illness, typically in a hospital setting, but treatment was consistently effective, even in high-risk patients, when hydroxychloroquine was given in a “cocktail” with azithromycin and, critically, zinc in the first 5 to 7 days after the onset of symptoms. The outcomes are, in fact, dramatic.
