1. How does 2019-nCoV spread?

2019-nCoV is a respiratory virus that mainly disperses when in contact with an infected person through droplets produced when an infected person coughs or runny nose. So each person needs to practice good hygiene. For example, paper towels to cover your nose and mouth when coughing, sneezing, runny nose, and then immediately throw paper towels into the trash. It is also necessary to wash your hands often with water and soap or hand sanitizer containing alcohol at concentrations above 60%.

2. Can 2019-nCoV be spread from person to person?

can. 2019-nCoV has been confirmed to be capable of human-to-human transmission, often due to close contact with an infected person.

Respiratory transmission

2019-nCoV can be transmitted by droplets

3. How long does 2019-nCoV have?

The incubation period is the period from the time of infection to the on onsub of symptoms. The estimated incubation period is currently between 2-12 days, and this time will be updated more accurately as more data is available. Based on information about other coronavirus diseases such as MERS and SARS, the incubation period of 2019-nCoV may be less than 14 days.

4. Can I get infected in 2019-nCoV from animals?

Detailed research shows that SARS-CoV is transmitted from civets to humans in China in 2002, and MERS-CoV transmitted from camels to humans in Saudi Arabia in 2012. Some strains of coronavirus exist only in animals that have not yet spread to humans.

It is unclear what animal 2019-nCoV is transmitted to humans. However this does not mean that you can get 2019-nCoV infection from any animal or from your pet. The first cases are highly likely to originate from animals in the animal market living in China. Protect yourself by avoiding visiting live animal markets, if forced to arrive, avoid direct contact with live animals and surfaces in contact with them.

It is necessary to avoid eating raw or uncooked animal products. Raw and cooked food processing tools should be used separately.

Animal Market

People should refrain from going to animal markets

5. Can I get 2019-nCoV from my pet?

No, there is currently no evidence that domestic pets such as dogs and cats were infected or distributed in 2019-nCoV.

6. Does the nCoV virus exist at the surface of the 20th hand? If so, how long does it last?

Have. However, it is unclear how long 2019-nCoV is likely to live on the surface, although initial information suggests that the virus may live several hours on the surface.

7. Is it safe to receive mail and parcels from China or other epidemic areas?

It's safe. Mail and parcel recipient is not at risk of infection 2019-nCoV. From experience with coronavirus strains, we know that this virus is unlikely to live long on objects such as letters and parcels.

8. Can corona virus "live" in seawater?

Not. Although there is currently no study on the viability of nCoV in seawater, 2019-nCoV is a virus that infects humans and they are difficult to "live" in seawater for the following reasons:

Viruses are actually not a living organism, they need to infect the host cell to maintain their existence. WHO has confirmed that nCoV does not live more than a few hours on the surface and does not infect through airborne (1), because these places do not have host cells, so after a few hours nCoV will lose its ability to infect due to environmental factors such as temperature, light, pH …. Seawater, too, is not home to host cells so that nCoV can live for more than a few hours. Even if the virus can live a few days in seawater, they will be immediately diluted in the vast sea to the extent that it is difficult to infect humans.

Viruses are a tiny body that is very sensitive to temperature, pH, light, ion levels, so they do not exist independently in the wild but need to live in the host cell. High concentrations of salts and other ions in seawater transform proteins on viral shells, making them infectable (2). The study also found that viruses in seawater are susceptible to closure leading to inability to infect (3). In addition, microorganisms in seawater are also capable of secreting antiviral substances (4). Indeed, research shows that seawater from different places is capable of inactivity of human viruses (4).

9. Are antibiotics effectively preventing and treating 2019-nCoV?

No, antibiotics are only capable of killing bacteria, not killing viruses. 2019-nCoV is a virus, so antibiotics do not have a role to prevent and treat 2019-nCoV.

medicine

Antibiotics have no role to prevent and treat 2019-nCoV

10. Can I get 2019-nCoV from someone who doesn't have symptoms of illness?

According to recent reports, people infected with 2019-nCoV can spread the virus before they have symptoms of the disease. However, current data shows that most infections are from symptomatic people.

11. Who is likely to become seriously ill with infection in 2019-nCoV?

The elderly, people with substrate diseases (such as diabetes, cardiovascular), people with immuno-deterioration disease are more susceptible to severe infection with this virus.

12. How dangerous is 2019-nCoV?

Is the Corona virus causing an epidemic in Wuhan really too scary? As with other respiratory diseases, 2019-nCoV infection can cause mild symptoms including runny nose, sore throat, cough, and fever. Symptoms can be more severe in some people and can lead to pneumonia or shortness of breath. More rarely, 2019-nCoV can be fatal. Older people and people with pre-20s (such as diabetes and heart disease) are more susceptible to severe symptoms of contracting the virus.
