What is SARS-CoV-2?SARS‐CoV‐2 belongs to the broad family of viruses known as coronaviruses.
How long does the virus that causes COVID-19 last on surfaces?Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.
What are coronavirus diseases?Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that can range from mild to lethal.
What are the known coronaviruses that can infect people?Human coronaviruses are capable of causing illnesses ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS, fatality rate ~34%). SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV.
When was the official name of SARS-CoV-2 announced?On 11 February 2020, the International Committee on Taxonomy of Viruses adopted the official name « severe acute respiratory syndrome coronavirus 2 » (SARS-CoV-2).
What 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.
What surfaces should be cleaned during the COVID-19 pandemic?High-touch surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices, personal computer keyboards, and work surfaces.
What are the long lasting fruits and vegetables I should buy for COVID-19 quarantine?
WHO recommends consuming a minimum of 400 g (i.e. 5 portions) of fruits and vegetables per day. Citrus fruits like oranges, clementines and grapefruit are good options, as well as bananas and apples, which can also be cut into smaller pieces and frozen for later consumption or to add to smoothies.
Root vegetables such as carrots, turnips and beets, as well as vegetables like cabbage, broccoli and cauliflower are relatively nonperishable. Garlic, ginger and onions are also great options to keep at home, as they can be used to add flavour to a variety of meals.
Can COVID-19 be transmitted through food?There is currently no evidence that people can catch COVID-19 from food. The virus that causes COVID-19 can be killed at temperatures similar to that of other known viruses and bacteria found in food.
Where were first COVID-19 infections 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.
When was COVID-19 first reported?On this website you can find information and guidance from WHO regarding the current outbreak of coronavirus disease (COVID-19) that was first reported from Wuhan, China, on 31 December 2019.
What is a disease outbreak?
A disease outbreak is the occurrence of disease cases in excess of normal expectancy. The number of cases varies according to the disease-causing agent, and the size and type of previous and existing exposure to the agent.
Disease outbreaks are usually caused by an infection, transmitted through person-to-person contact, animal-to-person contact, or from the environment or other media. Outbreaks may also occur following exposure to chemicals or to radioactive materials.
