Novel coronavirus (2019-nCoV)
In December, 2019, a pneumonia associated with the 2019 novel coronavirus (2019-nCoV) emerged in Wuhan, China.
On 31 December 2019, WHO was informed of a cluster of cases of pneumonia of unknown cause detected in Wuhan City, Hubei Province of China.
Early on, many of the patients in the outbreak in Wuhan, China reportedly had some link to a large seafood and animal market, suggesting animal-to-person spread. However, a growing number of patients reportedly have not had exposure to animal markets, indicating person-to-person spread is occurring.
There is currently no vaccine to prevent 2019-nCoV infection. The best way to prevent infection is to avoid being exposed to this virus. However, as a reminder, it is always recommended everyday preventive actions to help prevent the spread of respiratory viruses, including:
Wash your hands frequently
Wash your hands frequently with an alcohol-based hand rub or soap and water, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing
Why? Washing your hands with an alcohol-based hand rub or soap and water kills the virus if it is on your hands.
If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
Practice respiratory hygiene
When coughing and sneezing, cover mouth and nose with flexed elbow or tissue – discard tissue immediately into a closed bin and clean your hands with alcohol-based hand rub or soap and water.
Why? Covering your mouth and nose when coughing and sneezing prevent the spread of germs and viruses. If you sneeze or cough into your hands, you may contaminate objects or people that you touch.
Maintain social distancing
Maintain at least 1 meter (3 feet) distance between yourself and other people, particularly those who are coughing, sneezing and have a fever.
Why? When someone who is infected with a respiratory disease, like 2019-nCoV, coughs or sneezes they project small droplets containing the virus. If you are too close, you can breathe in the virus.
Avoid touching eyes, nose and mouth
Why? Hands touch many surfaces which can be contaminated with the virus. If you touch your eyes, nose or mouth with your contaminated hands, you can transfer the virus from the surface to yourself.
As a general precaution, practice general hygiene measures when visiting live animal markets, wet markets or animal product markets
Ensure regular hand washing with soap and potable water after touching animals and animal products; avoid touching eyes, nose or mouth with hands; and avoid contact with sick animals or spoiled animal products. Strictly avoid any contact with other animals in the market (e.g., stray cats and dogs, rodents, birds, bats). Avoid contact with potentially contaminated animal waste or fluids on the soil or structures of shops and market facilities.
Avoid consumption of raw or undercooked animal products
Handle raw meat, milk or animal organs with care, to avoid cross-contamination with uncooked foods, as per good food safety practices.
Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
Symptoms and complications
For confirmed 2019-nCoV infections, reported illnesses have ranged from people with little to no symptoms to people being severely ill and dying. Symptoms can include:
- Shortness of breath
Symptoms of 2019-nCoV may appear in as few as 2 days or as long as 14 after exposure. This is based on what has been seen previously as the incubation period of MERS viruses.
If you have fever, cough and difficulty breathing, seek medical care early
Tell your health care provider if you have traveled in an area in China where 2019-nCoV has been reported, or if you have been in close contact with someone with who has traveled from China and has respiratory symptoms.
Why? Whenever you have fever, cough and difficulty breathing it’s important to seek medical attention promptly as this may be due to a respiratory infection or other serious condition. Respiratory symptoms with fever can have a range of causes, and depending on your personal travel history and circumstances, 2019-nCoV could be one of them.
A medical mask is not required, as no evidence is
available on its usefulness to protect non-sick persons. However, masks might be worn in some countries according to local cultural habits. If masks are used, best practices should be followed on how to wear, remove, and dispose of them and on hand hygiene action after removal.
But people who have the infection or are at high risk for being exposed should wear a surgical face mask. Anyone caring for someone infected in a medical setting should wear a respirator mask as part of airborne precautions.
