There is a popular theory that the Covid-19 virus will disappear in the summer months. This is because the other corona viruses which are some of the viruses which cause the common cold tend to disappear in the warmer months. Outbreaks in Brazil, Ecuador and India would tend to throw cold water on that as would this recent article from Science. The first is a summary from Physician’s First Watch followed by a link to the article.
Pandemic in the summer: The warmth and humidity of the summer months may not offer substantial relief from the COVID-19 pandemic, according to a modeling study in Science. Researchers used data on two coronaviruses closely related to SARS-CoV-2 to predict the course of the pandemic over the coming months. They found that “while variations in weather may be important for endemic infections, during the pandemic stage of an emerging pathogen the climate drives only modest changes to pandemic size.” Instead, the population’s level of immunity has a much greater influence on an outbreak’s trajectory. The researchers conclude that “both tropical and temperate locations should prepare for severe outbreaks of [COVID-19] and that summertime temperatures will not effectively limit the spread” of the infection.
