What year is SARS

In 2002, SARS broke out in Guangdong, China, and spread to Southeast Asia and even the whole world. It was not until mid-2003 that the epidemic was gradually eliminated.

Clinical manifestations of SARS

The incubation period is 1 ~ 16 days, usually 3 ~ 5 days. Acute onset, strong infectivity, fever as the first symptom, chills, body temperature often exceeding 38℃, irregular fever or flabby fever, missed diagnosis of fever, etc. , and the thermal range is mostly 1 ~ 2 weeks; Accompanied by headache, muscle aches, general weakness and diarrhea. 3 ~ 7 days after onset, dry cough, less sputum, occasional bloodshot sputum, and no obvious lung signs.

10 ~ 14 days. Symptoms of infection and poisoning such as fever and fatigue are aggravated, and frequent cough, shortness of breath and dyspnea occur. A little exercise, asthma and palpitations will force you to stay in bed. This period is prone to secondary respiratory infection.

After 2-3 weeks, the fever gradually subsided, and other symptoms and signs were alleviated or even disappeared. The absorption and recovery of inflammatory changes in the lungs are slow, and it still takes about 2 weeks to fully absorb and return to normal after the body temperature is normal. Mild patients have mild clinical symptoms. Severe patients are seriously ill and prone to respiratory distress syndrome. Children seem to be less ill than adults. Fever is not the first symptom in a few patients, especially those with recent surgical history or basic diseases.

Transmission route of SARS

1, mainly transmitted through close respiratory droplets and close contact. In particular, the medical staff who perform tracheal intubation and tracheotomy on critically ill patients are in direct contact with a large number of respiratory droplets and are easily infected. There have been cases in which medical staff gather to be infected with SARS.

2. Other possible modes of transmission: The virus has been detected in feces, urine and blood of SARS patients, so other modes of transmission such as fecal transmission are not excluded.

For example, in the Taodayuan epidemic in Hong Kong, there were 1 SARS patients with diarrhea. Within four weeks, 328 people in this residential area were infected with SARS, and most of them developed diarrhea symptoms. In the end, the pollution of food or drinking water in the building was eliminated by the local authorities. It is likely that the U-shaped water collector at the ground outlet of the fecal drainage pipeline system was dry-adjusted, but it could not play the role of gas barrier, leading to sewage gasification and virus spread.
