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.

Where did COVID-19 origin?

The first known infections from SARS‑CoV‑2 were discovered in Wuhan, China.[17] The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.[19][75][9] Because many of the early infectees were workers at the Huanan Seafood Market,[76][77] it has been suggested that the virus might have originated from the market.[9][78] However, other research indicates that visitors may have introduced the virus to the market, which then facilitated rapid expansion of the infections.

Who issued the official name of COVID-19?

The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.

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.

Where 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.

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.

When was COVID-19 declared a pandemic?

The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020.

Who developed the Oxford-AstraZeneca COVID-19 vaccine?

Oxford-AstraZeneca's COVID-19 vaccine was developed in collaboration with Oxford University and is manufactured by AstraZeneca and COVISHIELD, licensed to and manufactured by AstraZeneca-SKBioscience (AZ-SKBio) in South Korea.

Who developed a no fault compensation scheme during the COVID-19 pandemic?

Along with COVAX partners, WHO has developed a no-fault compensation scheme as part of the time-limited indemnification and liability commitments.

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.

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.

What does it mean that coronaviruses are zoonotic?

Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.

Is COVID-19 caused by a virus or a bacteria?

The coronavirus disease (COVID-19) is caused by a virus, NOT by bacteria.

Do smokers suffer from worse COVID-19 symptoms?

Early research indicates that, compared to non-smokers, having a history of smoking may substantially increase the chance of adverse health outcomes for COVID-19 patients, including being admitted to intensive care, requiring mechanical ventilation and suffering severe health consequences.

How is the COVID-19 disease transmitted?

COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles containing the virus. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors. Transmission can also occur if splashed or sprayed with contaminated fluids in the eyes, nose or mouth, and, rarely, via contaminated surfaces.

How does COVID-19 spread?

The virus primarily spreads between people through close contact and via aerosols and respiratory droplets that are exhaled when talking, breathing, or otherwise exhaling, as well as those produced from coughs or sneezes.
