Can the COVID-19 virus survive in the summer?

There are indications that the COVID-19 virus, like many other viruses, survives less well in warm and humid conditions, such as those found in summer. However, this does not mean that the virus cannot survive or spread during the summer months.

Many respiratory viruses, such as influenza viruses, show seasonal patterns and are often more active in the winter months. This is due to factors such as cold and dry air, which can promote virus transmission, and more indoor activities that bring people closer together.

Higher temperatures and higher humidity can reduce the survival time of viruses on surfaces and in the air. UV light from the sun can also inactivate viruses more quickly. Studies have shown that the SARS-CoV-2 virus has a shorter survival time on surfaces at higher temperatures and higher humidity. This can reduce the risk of indirect transmission (via contaminated surfaces).

During the summer, people spend more time outdoors, where ventilation is better and the spread of the virus is less likely. However, mass gatherings and social activities can increase the risk of spread, regardless of the weather.

While warm and humid summer conditions may reduce the survival time of the COVID-19 virus, it is important to realize that this virus can still spread, especially through direct contact between people.
