personsand they are known to cause diseases ranging from the common cold to more serious diseases, such as the Middle East respiratory syndrome ( MERS) and Severe acute respiratory syndrome (SARS).
- What is a “novel” virus crown ?
A novel virus crown (CoV) is a new strain of virus crown that has not been previously identified in humans. The new, or “novel” virus crown , now called 2019-nCoV, had not previously detected before the outbreak was reported in Wuhan, China in December 2019.
- Can the 2019-ncov be transmitted from person to person?
Take care of your health by doing the following:
Wash your hands frequently with an alcohol or water and soap based hand sanitizer.
Why? Washing your hands with an alcohol or soap-based hand sanitizer and water kills the
virusif it's in your hands .
Maintain social distancing – maintain at least 1 metre (3 feet) distance between yourself and other persons , particularly those who are coughing, sneezing and have 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 your 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.
If you have a fever, cough and trouble breathing, seek medical attention early. Tell your healthcare provider if you have traveled to an area of China where 2019-nCoV has been reported, or if you have been in close contact with someone who has traveled from China and has breathing problems.
Why? Whenever you have a fever, cough and shortness of breath, it is important to seek medical attention immediately, as this may be due to a respiratory problem.
infectionor other serious condition. Respiratory symptom with fever can have a range of causes, and depending on your personal travel history and circumstances, 2019- nCoV could be one of them.
If you have mild respiratory symptom and no travel history to or within China, carefully practice basic respiratory and hand hygiene and stay home until you are recovered, if possible.
- How dangerous is it
As with other respiratory illnesses, infection with 2019-nCoV can cause mild symptom including a runny nose, sore throat, cough, and fever. It can be more severe for some persons and can lead to pneumonia or breathing difficulties. More rarely, the disease can be fatal. Older persons , and persons with pre-existing medical conditions (such as, diabetes and heart disease) appear to be more vulnerable to becoming severely ill with the virus .
- Can humans become infected with the 2019-ncov from an animal source?
Detailed investigations found that SARS-CoV was transmitted from civet cats to humans in China in 2002 and MERS -CoV from dromedary camels to humans in
Saudi Arabiain 2012. Several known virus crown es are circulating in animals that have not yet infected humans. As surveillance improves around the world, more virus crown es are likely to be identified. The animal source of the 2019-nCoV has not yet been identified.
This does not mean you can catch 2019-nCoV from any animal or from your pet. It’s likely that an animal source from a live animal market in China was responsible for some of the first reported human infection s. To protect yourself, when visiting live animal markets, avoid direct unprotected contact with live animals and surfaces in contact with animals.
The consumption of raw or undercooked animal products should be avoided. Raw meat, milk or animal organs should be handled with care to avoid cross contamination with raw foods, in accordance with good food safety practices.
- Can I catch my pet's 2019-ncov?
No, there is currently no evidence that pets or pets, such as cats and dogs, have been infected or spread 2019-nCoV.
- Should I wear a mask to protect myself?
Wearing a medical mask can help limit the spread of some respiratory disease. However, using a mask alone is not guaranteed to stop infection s and should be combined with other prevention measures including hand and respiratory hygiene and avoiding close contact – at least 1 metre (3 feet) distance between yourself and other persons .
WHO advises on rational use of medical masks thus avoiding unnecessary wastage of precious resources and potential mis-use of masks (see Advice on the use of masks). This means using masks only if you have respiratory symptom (coughing or sneezing), have suspected 2019-nCoV infection with mild symptom or are caring for someone with suspected 2019-nCoV infection . A suspected 2019-nCoV infection is linked to travel in an area in China where 2019-nCoV has been reported, or close contact with someone who has travelled from China and has respiratory symptom .
- How to put on, wear, take off and get rid of a mask?
- Who can catch this virus?
People living or travelling in an area where the 2019-nCoV virus is circulating may be at risk of infection . At present, 2019-nCoV is circulating in China where the vast majority of persons infected have been reported. Those infected from other countries are among persons who have recently traveled from China or who have been living or working closely with those travellers, such as family members, co-workers or medical professionals caring for a patient before they knew the patient was infected with 2019-nCoV.
Health workers caring for persons who are sick with 2019-nCoV are at higher risk and must protect themselves with appropriate infection prevention and control procedures. People living outside of areas in China where the virus is circulating are not at risk of infection with 2019-nCoV.
WHO is continuously monitoring the epidemiology of this outbreak to better understand where the virus is circulating and how persons can protect themselves from infection .
- Who is at risk of developing a serious illness?
While we still need to learn more about how 2019-nCoV affects persons , thus far, older persons , and persons with pre-existing medical conditions (such as diabetes and heart disease) appear to be more at risk of developing severe disease.
- How does this virus spread?
The new virus crown is a respiratory virus which spreads primarily through contact with an infected person through respiratory droplets generated when a person, for example, coughs or sneezes, or through droplets of saliva or discharge from the nose. It is important that everyone practice good respiratory hygiene. For example, sneeze or cough into a flexed elbow, or use a tissue and discard it immediately into a closed bin. It is also very important for persons to wash their hands regularly with either alcohol-based hand rub or soap and water.
- How long does the virus survive on surfaces?
It is still not known how long the 2019-nCoV virus survives on surfaces, although preliminary information suggests the virus may survive a few hours. Simple disinfectants can kill the virus making it no longer possible to infect persons .
- What’s the difference between illness caused by 2019-ncov infection , the flu or a cold?
People with 2019-nCoV infection , the flu, or a cold typically develop respiratory symptom such as fever, cough and runny nose. Even though many symptom are alike, they are caused by different virus es. Because of their similarities, it can be difficult to identify the disease based on symptom alone. That’s why laboratory tests are required to confirm if someone has 2019-nCoV.
As always, WHO recommends that persons who have cough, fever and difficulty breathing should seek medical care early. Patients should inform health care providers if they have travelled in the 14 days before they developed symptom , or if they have been in close contact with someone with who has been sick with respiratory symptom .
- How long is the incubation period?
The incubation period is the time between infection and the onset of clinical symptom of disease. Current estimates of the incubation period range from 2-11 days, and these estimates will be refined as more data become available. Based on information from other virus crown diseases, such as MERS and SARS, the incubation period of 2019-nCoV could be up to 14 days.
- Can 2019-ncov be caught from a person who presents no symptom ?
Understanding the time when infected patients may spread the virus to others is critical for control efforts. Detailed medical information from persons infected is needed to determine the infectious period of 2019-nCoV. According to recent reports, it may possible that persons infected with 2019-nCoV may be infectious before showing significant symptom . However, based on currently available data, the persons who have symptom are causing the majority of virus spread.
- Who has changed their advice on health protection?
No, our advice is the same. WHO has issued advice to persons on how to protect themselves from 2019-nCoV infection , as for any virus that spreads via the respiratory route.
In addition, it is vitally important in health care settings that health care workers are able to protect themselves from infection .
- Is it safe to receive a package from china or any other place where the virus has been identifie
Yes, it is safe. People receiving packages are not at risk of contracting the new virus crown . From experience with other virus crown es, we know that these types of virus es don’t survive long on objects, such as letters or packages. Are antibiotics effective in preventing and treating the 2019-ncov? No, antibiotics do not work against virus es, they only work on bacterial infection s. The novel virus crown is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment.
- Are there any specific medications to prevent or treat 2019-ncov?
To date, there is no specific medicine recommended to prevent or treat the novel virus crown . However, those infected with 2019-nCoV should receive appropriate care to relieve and treat symptom , and those with severe illness should receive optimized supportive care. Some specific treatments are under investigation and will be tested through clinical trials. WHO is helping to coordinate efforts to develop medicines to treat nCoV with a range of partners.
If you want to protect yourself from getting infected with the new virus crown , you should maintain basic hand and respiratory hygiene, and safe food practices and avoiding close contact, when possible, with anyone showing symptom of respiratory illness such as coughing and sneezing.
The following measures are NOT specifically recommended as 2019-nCoV remedies, as they are not effective in protecting yourself and may even be harmful:
In any case, if you have fever, cough and difficulty breathing seek medical care early to reduce the risk of developing a more severe infection and be sure to share your recent travel history with your health care provider.
