Knowledge of 2019-nCoV

1. What is the 2019-nCoV?

The coronavirus separated from the lower respiratory track of pneumonia patients with unknown cause in Wuhan is a novel coronavirus, which is designated as 2019-nCoV by WHO.

2. What kind of people are inclined to be infected by the 2019-nCoV?

All people are inclined to be infected by the 2019-nCoV. The 2019-nCoV may outbreak in the population with low immunologic function or with normal immunologic function, and its outbreak is correlated to the amount of contacted coronavirus. All people with lower immunologic function, such as the old people, pregnant and lying-in woman, people with abnormal hepatorenal function or people with chronic diseases, may get worsened disease after being infected.

3. What are the spreading ways of 2019-nCoV?

The primary spreading ways are the droplet spreading, the contact spreading (including self-vaccination caused by hand pollution) and close contact of aerosol from respiratory track.
Currently the most primary spreading way is the droplet spreading.

4. What is the latent period of 2019-nCoV?

The latent period of the 2019-nCoV is as long as 10~14 days or as short as 2~3 days, and is averagely 7 days; In some cases, the 24-day long latent period will also occur.Since it is highly
infectious, the patients with latent 2019-nCoV are also infectious.

5. Precautions for close contacts

All persons contacted with suspected cases (including medical personnel) should have a health observation period of 14 days. The observation period starts from the last day when the suspected case is contacted. Once there is symptom such as fever, or the respiratory symptom such as cough, shortness of breath or diarrhea, the patient must go and see the doctor immediately.

6. Suggestions on monitoring of close contacts

(1) In case that the close contact outbreaks symptoms, he/she must report the hospital immediately and see a doctor in the regular hospital.

(2) The patient must wear the medical respirator on the way to hospital.

(3) Avoid from taking public transportation, call the ambulance or use private car to transport patient,open the window of car on the way if possible.

(4) All sick close contacts must keep the respiratory track healthy and both hands clean at all times. Keep far away from other persons (1m or above) when standing or sitting on the way or in the hospital.

(5) The surfaces of every object polluted by the secretion of respiratory tract or body fluid of the sick close contacts should be cleaned and sterilized with the sanitizer containing the diluted bleaching agents.

7. What are the clinical manifestation of 2019-nCoV pneumonia patient?

The clinical manifestation of the 2019-nCoV pneumonia patient is the fever, with the complications of dry cough, lacking in strength, difficulty in breathing, diarrhea, as well as the seldom symptoms of running nose, expectoration. Certain patients may have the minor disease onset symptom and may have no fever, but may feel headache, palpitation, chest distress, conjunctivitis, mild soreness in limbs, waist or back’s muscular. Certain patients may get difficulty in breathing one week later and the patient with worsen disease may further worsen quickly. Most of patients may have  favourable prognosis, and few patients may worsen and die.

8.Prevention and control measures of 2019-nCoV pneumonia

Prevention and control measures for contact and droplet: wash hands frequently and wear respirator before going outside.

Ventilate every room frequently;

Keep clean and sterilized: the 2019-nCoV is very sensitive to the heat, so it can be deactivated if soaking in the hot water of 56℃ for 30 minutes or is sterilized with 75 % ethyl alcohol,
chlorine-containing disinfectant or chloroform.
