Sorting fact from fiction

Epidemic-related online posts identified as rumors by the authorities:

1. Rumor: Novel coronavirus pneumonia is a type of severe acute respiratory syndrome, or SARS, virus.

Fact: It may share some genetic similarities with the SARS virus, but it is inaccurate to say it is a type of this virus.

2. Rumor: Smokers have been infected amid the outbreak at a far lower rate than non-smokers.

Fact: There are no findings or data showing that nicotine, a major component of cigarettes, has an anti-viral effect or prevents infection. On the contrary, it can cause respiratory failure and paralysis.

3. Rumor: During the outbreak, people should wear goggles when going out.

Fact: There is no need for this, according to epidemiologist Li Lanjuan. Only doctors on the front-line should wear protective goggles or surgical masks when diagnosing and treating patients.

4. Rumor: Pets, such as dogs and cats, can become infected with the virus.

Fact: There are no findings to show that such animals can become infected, but it is always a good idea for owners to wash their hands after contact with their pets.

5. Rumor: The higher the alcohol level in a disinfectant, the more effective it is.

Fact: Ethanol at a concentration of 60 to 80 percent proves an effective antiseptic. But a 90 percent alcohol level may reduce effectiveness of disinfection.

6. Rumor: It is no longer safe to eat seafood, chicken or pork.

Fact: The virus possibly arose from the illegal sale of wild animals. Eating meat and seafood sold through recognized channels will not pose a risk of infection.

7. Rumor: Taking a hot bath can kill the virus.

Fact: The virus is vulnerable to heat, but can only become inactive after exposure to a temperature of 56 C for more than 30 minutes.

8. Rumor: Eating garlic can prevent infection from the virus.

Fact: There is no evidence to prove that this helps, although garlic is a healthy food that may have some antimicrobial properties.

9. Rumor: Wearing more than one surgical mask will help prevent infection from the virus.

Fact: According to medical experts, people can protect themselves if they wear a mask correctly. Wearing additional ones will not work, but will be a waste of resources and may even make it more difficult to breathe.

10. Rumor: Using a mouthwash will offer protection from the virus.

Fact: There is no evidence of this, although some brands can eliminate certain microbes in saliva for a few minutes.
