How long does it take for the new coronavirus to develop?

The incubation period of the 2019 novel coronavirus has not yet been fully determined. The longest period found so far is 12 days, but for coronavirus, the incubation period is about 2 weeks and no longer than 15 days.

For those who have close contact with patients, based on relevant experience and medical records, the current medical observation period is set at 14 days. That is, people who live, work, and study with patients, as well as the patients' caregivers, medical staff, and close contacts, need to undergo 14 days of home medical observation.

If any abnormal symptoms such as fever or cough occur during the observation period, the patient should be sent to a designated medical institution for screening, diagnosis and treatment in a timely manner.

What are the atypical symptoms of the new coronavirus?

The initial symptoms of novel coronavirus infection are mostly fever and cough without sputum, often with a small amount of sticky sputum in the early stage, fatigue, chest tightness, and nasopharyngeal symptoms, such as sore throat, nasal congestion and other non-specific symptoms. Some mild patients may not have fever symptoms.

Elderly people and immunosuppressed people may experience atypical symptoms. Patients may gradually develop breathing difficulties. Severe cases may lead to acute respiratory distress syndrome, abscess shock, coagulation dysfunction and difficult-to-correct metabolic acidosis, which are manifested as breathing difficulties, rapid heart rate, weak pulse, hypotension, skin ecchymoses and even oliguria.

Most patients infected with the new coronavirus have mild symptoms and have a good prognosis with timely, systematic and effective symptomatic supportive treatment. A small number of patients have critical conditions and some may even die.
