This thinking can be true for several seasonal viruses, but COVID-19 is not the flu. Seasonality has the potential to decrease the rate of infection, but this factor alone won’t get us anywhere close to resolving the outbreak. Globally many hot climate countries are dealing with this virus and the weather has not affected its spread.
The first time a severe infectious disease moves through a new population no one is immune, leaving the virus numerous hosts to sustain it for months regardless of seasons. Once it subsides, future infections may impact smaller populations and they could reveal a seasonal cycle.
As the pandemic continues to evolve, we are better to focus on things we can control such as practicing good hygiene, avoiding crowds and being mindful of our surroundings not only to protect ourselves but those around us that are vulnerable and depend on the actions of their community.
