Scientists link coronavirus infectivity to cold weather: study

The video discusses a study from Public Health that suggests low humidity may increase COVID-19 infectiousness. It explores how colder climates and high altitudes might contribute to higher infection rates, as observed in countries with more cases. The study tracks COVID-19's progression since the Wuhan outbreak, correlating cases with average monthly temperatures. Results indicate that countries in high latitudes have higher infection rates, suggesting cold environments as a risk factor. Researchers from Central University of Rajasthan and Banaras Hindu University caution that more research is needed to confirm the temperature-COVID-19 link, but note that warmer weather could potentially reduce infections.
