People infected with the novel coronavirus are contagious.
latency usually refers to the time from the beginning of the pathogen that is infected to the occurrence of clinical symptoms and signs. The latency period is generally asymptomatic. Based on current epidemiological investigations and clinical practice, the incubation period of novel coronavirus infection is generally 3-7 days, with a maximum of no more than 14 days. The incubation period is asymptomatic, but it is contagious. Therefore, people who come into contact with infected people should be quarantined at home for at least 14 days in time to block the chain of infection. During this period, if symptoms such as fever, dry cough, fatigue occur, you should seek medical treatment in a timely manner and provide medical staff with as detailed channels for contact with infection as possible. In order to reduce the risk of infection, the following protective measures should be taken.
1. Wear a mask
can choose medical surgical mask , N95 and KN95 masks. For daily travel, medical surgical masks can already meet the protection needs; if you need to contact people with fever or cough, the protection effect of using N95/KN95 masks is better.
2. Clean hands in a timely and effective manner
"Wash hands frequently" is currently recognized as one of the effective methods to prevent pneumonia caused by the novel coronavirus. Wash your hands in time after going out, and keep your hands clean and hygienic in public places can reduce the virus infection rate. After covering your mouth with your hands and cough, before and after meals, after toileting, when you go out to contact animals (especially wild animals) or their excrement, you must wash your hands.
3. Do not go to densely populated areas
The new coronavirus is mainly transmitted through droplets, and densely populated areas will greatly increase the possibility of coronavirus transmission.
4. Avoid eating and contacting wild animals
According to the progress of the research on the novel coronavirus in the National Health Commission, the new coronavirus may come from wild animals. Therefore, do not contact any wild animals, and do not eat them, so as to avoid direct infection.
5. Stay away from suspected infections and take protective measures
If you encounter suspected symptoms such as fever, fatigue, dry cough or suspicious people from the epidemic area during your trip, please stay away in time. If you are close to such people or have some contact, in addition to wearing masks in time, use wet wipes, hand sanitizer, etc. you carry with you to avoid infection, and quarantine at home for at least 14 days.
6. Avoid rubbing your eyes directly with your hands. If possible, you can wear goggles
The novel coronavirus mainly causes infection through droplets entering the respiratory mucosa, and the conjunctiva of the eye is also one of the routes of infection. If droplets directly enter the eyes or rub the eyes, it can also cause infection. Therefore, do not rub your eyes at will. If you are in a severe epidemic area, especially those who have been treated with confirmed patients with novel coronavirus infection, you can wear goggles according to the doctor's advice if you have the conditions.
