New coronavirus (2019-nCoV): Rumors and Facts


Can I reuse N95 masks? Can I wash it? Can it be disinfected by hand disinfectant?
No. Masks, including flat medical masks or N95 masks, cannot be reused. If you have had close contact with a person with a new coronavirus infection or another patient with a respiratory infection, the front of your mask should be considered contaminated, and it should be removed without touching the front of the mask and handled properly. After removing the mask, you should wash your hands with alcohol-free hand sanitizer or with soap and water.

Can whole body spray with alcohol or chlorine kill the new coronavirus?
No. Spraying alcohol or chlorine all over the body does not kill viruses that have already entered the body. Spraying such substances may be harmful to clothing or mucous membranes (ie eyes, mouth). Please note that alcohol and chlorine may be useful for disinfecting a variety of surfaces, but follow appropriate recommendations when using them.
There are several things you can do to protect yourself from the new coronavirus. First, wash your hands frequently with alcohol-free hand sanitizers or with soap and water. For other protective measures, please consult WHO's recommendations.

Can hand dryers like those in public toilets kill 2019-nCoV in 30 seconds?
No. The hand dryer cannot effectively kill 2019-nCoV. To protect yourself from the new coronavirus, you should always wash your hands with alcohol-free hand sanitizer or soap and water. After washing your hands, wipe them thoroughly with paper towels or dry them with a warm air dryer.

Can UV disinfection lamps kill new coronaviruses?
Ultraviolet light should not be used to disinfect hands or other skin areas, as ultraviolet radiation can cause erythema (skin irritation).
To prevent yourself from becoming infected with the new coronavirus, keep an eye on all the steps you can take, as detailed on the WHO website.

Is it safe to receive a letter or package from China?
Is safe. People who receive packages from China are not at risk of contracting the new coronavirus (2019-nCoV).
Based on previous analysis, we know that coronaviruses do not survive long on objects such as packages or letters.

Can asymptomatic patients also spread the new coronavirus?
Based on available data, the new coronavirus (2019-nCoV) is mainly transmitted by patients who have developed symptoms.
WHO has recognized the possibility of transmission to infected persons before symptoms appear. Based on observations of MERS (Middle East Respiratory Syndrome), transmission of other coronaviruses through asymptomatic patients is rare. Therefore, asymptomatic patients may not be the main spreaders of the virus.

Are there medicines specifically for the prevention and treatment of new coronaviruses?
To date, there are no drugs specifically designed to prevent and treat new coronaviruses.
Those infected should receive treatment for remission and symptomatic treatment, while patients with severe disease should receive the best supportive treatment for all their symptoms.
Specific treatments are under study and will be tested in clinical trials. WHO is working with partners to help accelerate research and development.

Are antibiotics effective in preventing and treating new coronaviruses?
Antibiotics are not effective against viruses, but only against bacteria. The new coronavirus (2019-nCoV) is a virus, so antibiotics should not be used as a preventive or therapeutic approach.
However, if you are hospitalized with a new coronavirus, you may be treated with antibiotics because you may be infected with bacteria at the same time.

How does WHO recommend using a mask?
    Wash your hands before wearing a mask.
    Do not touch the face of the mask with your hand, wear and remove it through the cord at both ends.
    If the mask becomes wet during wearing, replace it.
    Immediately after removing the mask, throw it into the trash can and wash your hands.
Keep in mind that wearing a mask alone cannot provide complete protection.
Washing your hands frequently, covering your mouth and nose with a tissue or a curved elbow when you cough or sneeze, and maintaining social distance are all important.

Will pets spread the new coronavirus?
Currently, there is no evidence that pets such as dogs and cats will be infected with the new coronavirus (2019-nCoV). However, after contact with pets, washing hands with soap and water can significantly reduce the transmission of other common bacteria between pets and humans, such as E. coli and Salmonella.

Is a body temperature scanner effective in detecting new coronavirus infections?
Yes, the temperature scanner is effective in detecting people who have a fever due to infection with the new coronavirus (2019-nCoV).
However, if you are infected but have not had a fever, it cannot be detected by a temperature scanner. This is because it takes 2-10 days for an infected person to get sick and have a fever.

Will new coronaviruses affect older people? Are young people vulnerable too?
People of all ages can be affected by the new coronavirus (2019-nCoV). People who are older and suffering from asthma, diabetes, heart disease, etc. may be more likely to contract the virus.
WHO recommends that people of all ages take steps to protect themselves from viral infections, such as hygienic habits to keep hands clean and respiratory health.

Can oseltamivir treat new coronaviruses?
There is no evidence that oseltamivir can treat a new coronavirus (2019-nCoV) infection.
WHO is working urgently with researchers and doctors around the world to study possible viral treatments, including observing whether existing antiviral drugs are effective against the virus.
However, this work is still in its infancy and no recommendations have been made.

Can eating garlic prevent new coronavirus infections?
Garlic is a healthy food and may have some antibacterial properties.
However, from the current outbreak, there is no evidence that consumption of garlic can protect people from the new coronavirus (2019-nCoV) infection.

Does regular nose washing with saline help prevent new coronavirus infections?
There is no evidence that regular irrigation of the nose with saline can prevent infection with the new coronavirus (2019-nCoV).
There is limited evidence that regular nose washing with saline can help people recover more quickly from the common cold. However, regular nose washing does not prevent respiratory infections.

Can sesame oil prevent new coronaviruses from entering the body?
Sesame oil does not kill the new coronavirus (2019-nCoV).
Some chemical disinfectants can kill new coronaviruses on the surface of objects, such as bleach / chlorine-based disinfectants, ether solvents, 75% ethanol, peracetic acid and chloroform.
However, if they are placed on the skin or under the nose, they have little effect on the virus. Applying these chemicals to the skin is even dangerous.
