Variations in climate and global spread of COVID-19: Implications for control in tropical and warmer climates
Health and climatic changes have been linked for centuries. Viruses, bacteria, fungi and parasites are sensitive to environmental conditions including ambient temperature, humidity, smog, and other climatic factors like exposure to sunlight. Viral respiratory tract infections such as seasonal influenza are known to become epidemic primarily during cold weather conditions influenced also by population density and travel patterns.

Understanding how the emergence and spread of COVID-19 could be affected by climatic conditions may be an important aspect for disease control.
