Fibers longer than 5μm are rarely found in rural areas.

Several explanations contributing to the milder COVID-19 symptoms experienced, in the acute phase, by children have been suggested, including: [16] [17] a lower expression of ACE-2 (the receptor used by SARS-CoV-2 for cell entry) in the respiratory tract in younger children; viral interference (e.g. by other coronaviruses)
