We Show That Mask Efficacy Strongly Depends On Airborne Virus Abundance. Based On Direct Measurements

Face masks effectively limit the probability of SARS-CoV-2 transmission
Science
Airborne transmission by droplets and aerosols is important for the spread of viruses. Face masks are a well-established preventive measure,

We show that mask efficacy strongly depends on airborne virus abundance. Based on direct measurements of SARS-CoV-2 in air samples and population-level infection probabilities, we find that the virus abundance in most environments is sufficiently low for masks to be effective in reducing airborne transmission.

[...] Wearing masks can indeed keep the number of inhaled viruses in a low Pinf regime and explain the observed efficacy of face masks in preventing the spread of COVID-19.

However, unfavorable conditions and the large variability of viral loads may lead to a virus-rich regime in certain indoor environments, such as medical centers treating COVID-19 patients. In such environments, high efficiency masks and further protective measures like efficient ventilation should be used to keep the infection risk low.

Republican Voters Are In A Codependent Relationship With An Abusive Congress.

Republican voters are in a codependent relationship with an abusive Congress.

Each side must support the same poisonous gun rhetoric. They must live in fear.

They both can't quit guns, because once they do mature and look at the world as adults, they have no need for each other.
