The first known infections from SARS-CoV-2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.
What are the Unity Studies in the context of the COVID-19 pandemic?
WHO, in collaboration with technical partners, has developed several standardized generic epidemiological investigation protocols branded as UNITY studies. These studies aim to support national public health and social measures, promote the international comparability of research and address gaps in current knowledge regarding the COVID-19 pandemic.
How does coronavirus disease spread?
COVID-19 is transmitted from person to person via droplets, contact, and fomites. It is transmitted when one individual talks, sneezes, or coughs producing ‘droplets’ of saliva containing the COVID-19 virus. These droplets are then inhaled by another person. COVID-19 transmission usually occurs among close contacts -- including family members and healthcare workers. It is therefore important to maintain a distance of more than 1 meter away from any person who has respiratory symptoms
