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.
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.
Can the coronavirus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).
The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.
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).
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.
Can I get COVID-19 while swimming?
The COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person.
WHAT YOU CAN DO:
Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell.
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.
What 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.
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.
Can the coronavirus disease be transmitted through the consumption of cooked foods, including animal products?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.
Is COVID-19 caused by a virus or a bacteria?The coronavirus disease (COVID-19) is caused by a virus, NOT by bacteria.
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.
How do I disinfect surfaces during the coronavirus disease pandemic?
In non-health care settings, sodium hypochlorite (bleach / chlorine) may be used at a recommended concentration of 0.1% or 1,000ppm (1 part of 5% strength household bleach to 49 parts of water). Alcohol at 70-90% can also be used for surface disinfection. Surfaces must be cleaned with water and soap or a detergent first to remove dirt, followed by disinfection.
Cleaning should always start from the least soiled (cleanest) area to the most soiled (dirtiest) area in order to not spread the dirty to areas that are less soiled.
