How long have coronaviruses existed?
COVID-19Dažnas klausimasHow long have coronaviruses existed?The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.
Where was COVID-19 first discovered?
COVID-19Dažnas klausimasWhere was COVID-19 first discovered?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 some of the ways by which COVID-19 is transmitted?
COVID-19Dažnas klausimasWhat are some of the ways by which COVID-19 is transmitted?COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors.

What is the natural reservoir for SARS-CoV-2?
COVID-19Dažnas klausimasWhat is the natural reservoir for SARS-CoV-2?The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.2020-02-21
What is the origin of COVID-19?
COVID-19Dažnas klausimasWhat is the origin of COVID-19?Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel severe acute respiratory syndrome coronavirus. It was first isolated from three people with pneumonia connected to the cluster of acute respiratory illness cases in Wuhan. All structural features of the novel SARS-CoV-2 virus particle occur in related coronaviruses in nature.
