1. What is an asymptomatic carrier?

Asymptomatic carriers refer to those who have tested positive via a nucleic acid test, but do not show clinical symptoms such as fever or fatigue. They are infected with the virus but do not develop any typical symptoms. Even they themselves are unaware of their own illness.

2. What kind of people will become asymptomatic carriers?

Based on current cases, asymptomatic carriers are mainly the close contacts of confirmed cases, especially the patients' family members.

3. Are asymptomatic carriers contagious?

At present, the major sources for transmission are patients infected with NCP. So asymptomatic carriers can be contagious as well.

4. What are the transmission routes of NCP?

Patients, whether showing symptoms or not, contract NCP mainly through respiratory droplets and contact transmission.

5. Will asymptomatic carriers become the super spreader?

Based on the current information, only a small minority of patients are asymptomatic carriers. They are mildly ill and less contagious as they carry a low viral load, thus posing little threat to others.

6. Is it necessary to put asymptomatic carriers in quarantine?

If available, close contacts of patients should all be quarantined in designated medical institutions, including asymptomatic carriers.

7. Am I an asymptomatic carrier?

You do not have to worry too much if you have no travel or residence history in Wuhan and its surrounding areas in the past fortnight, no one in your family has been diagnosed with NCP or you have no contacts with confirmed or suspected cases. Otherwise, you should report your condition promptly and be quarantined for medical diagnosis and treatment.

8. What else should we be informed of regarding asymptomatic carriers?

The proportion of patients with mild symptoms is higher in NCP patients than that in SARS or MERS. There is no definite boundary between patients with mild symptoms and asymptomatic carriers. The patients themselves may not notice the difference. Thus, a series of medical examination and diagnosis is needed before anyone is identified as an asymptomatic carrier.

9. How should you protect yourself?

You can stop the spread of the virus by staying home as much as possible, avoiding gatherings, wearing a mask when going out and washing hands frequently. These measures are also effective when you are around asymptomatic carriers. You should maintain good hygiene at home, keep furniture and tableware clean and open the windows regularly for better ventilation. Family members should avoid sharing towels with each other.
