SARS information, shorter, SARS related information

The following precautions can be taken mainly:

Develop and maintain good personal hygiene, wash hands after sneezing, coughing and cleaning your nose; After washing your hands, dry them with a clean towel and paper towel. Don't share towels.

Eat a balanced diet, dress more or less according to climate change, exercise regularly, and get enough rest. Reduce stress and avoid smoking, go outdoors often, breathe fresh air and strengthen your body's resistance.

Ventilation is often used indoors to promote air circulation, pay attention to the cleanliness and hygiene of the living environment, and dry clothes and quilts frequently. (If the air conditioner is installed indoors, the air conditioning equipment should be maintained in good performance, and the dust filter should be cleaned frequently to ensure the safety of air supply.) ）

Avoid going to public places with poor air clearance, dense populations, or staying in confined spaces for long periods of time.

If you have any symptoms, you should seek medical attention promptly.

Suspected wildlife infected people, so far, the cause of the disease is unknown.

The causative agent of the SARS outbreak has not yet been conclusively determined, and domestic experts have found chlamydia-like particles in the samples taken from 5 cases of SARS patients, while some experts abroad believe that it may be a virus, mainly focusing on coronavirus or paramyxovirus. Domestic experts have ruled out plague, pulmonary anthrax, leptospirosis, epidemic hemorrhagic fever, Legionnaires' disease and other pathogens, and are now focusing on research to confirm whether they belong to several key pathogens such as coronavirus and chlamydia.

Experts from the World Health Organization and other agencies pointed out on the 9th that the new coronavirus that causes atypical pneumonia not only has more survival than originally estimated, but also gradually weakens its lethality after a few mutations in a short period of time as they originally thought, so the harm of this virus needs to be more comprehensively assessed.

Earlier, scientists had predicted that as the number of SARS infections increased, it would mutate, weakening its infectivity and lethality. But after comparing 14 strains of the virus from SARS patients around the world, they found that the genetic mutations of the SARS virus were far smaller than earlier expected, and none of them made it less harmful.

David Heyman, executive director of infectious diseases at the World Health Organization, said in Geneva that they are now convinced that the SARS virus is well adapted to human transmission and that its contagiousness is persistent. On the other hand, the stability of the virus means that more targeted drugs and vaccines can be developed, but the coronavirus family has always been highly resistant, and the task ahead scientists is quite difficult.

More than 30 countries and regions.

The outbreak of SARS in 2003 was an epidemic crisis faced by many countries and regions around the world, among which Chinese mainland was the hardest hit area. According to the statistics of the World Health Organization, from November 1, 2002 to 2 p.m. Geneva time on June 9, 2003, the SARS epidemic that swept through more than 30 countries and regions has led to a total of 8,421 clinically reported cases worldwide, including 5,328 cases in Chinese mainland, accounting for 63; There were 784 deaths worldwide, of which 340 were in Chinese mainland, accounting for 44.

SARS has been circulating in mainland China since November 2002, which can be roughly divided into two stages: from November 2002 to March 2003, the epidemic mainly occurred in Guangdong and Hong Kong; Since March 2003, the epidemic has spread to the whole country, especially in Beijing. On June 24, 2004, the World Health Organization (WHO) announced the lifting of the travel ban on Beijing, indicating the victory of Chinese mainland in the fight against SARS.

Severe acute respiratory syndrome (SARS) is a type of atypical pneumonia. After the causative agent of the condition has been identified, the World Health Organization (WHO) designates it as "Severe Acute Respiratory Syndrome" based on the characteristics of the disease. There are also ** transliteration of the disease as SARS, SARS, SARS or SARS according to the English abbreviation.

Due to the similarity between SARS and HKSAR, the Hong Kong government used to refer to the virus as SRS, which stands for acute"a"Delete.

The SARS virus was discovered by Carlo Urbani. Vulbani is an Italian physician at the World Health Organization. He contracted the virus while studying the virus in Vietnam and died in Thailand in March 2003.

Studies have shown that the disease is caused by a previously undetected member of the Coronaviridae family, which is supposed to be transmitted by droplets coughed up by an infected person, and that the infection requires close contact. The disease causes an average of 7% to 15% of deaths. But the exact figures, according to the World Health Organization, vary from place to place.

The World Health Organization (WHO) also warns that the mortality rate could reach 15% in the future. The mortality rate for different age groups is 1% for people aged 24 and under, 6% for those aged 25 to 44, 15% for those aged 45 to 64, and more than 50% for those over 65 years old.

The spread of the virus is caused by humans eating wild animals and has been linked to many diseases in humans and animals. The representative strains are avian infectious gastroenteritis virus, rat coronavirus, etc. Coronaviruses can infect all age groups, with 29% between 0 and 4 years old and 22% over 40 years old.

Severe acute respiratory syndrome, also known as infectious atypical pneumonia, abbreviated as SARS, is a new respiratory infectious disease caused by infection with SARS coronavirus. It is mainly transmitted through short-range airborne droplets, with fever, headache, muscle aches, fatigue, dry cough and less phlegm as the main clinical manifestations, and respiratory distress may occur in severe cases. The disease is highly contagious and has significant clusters in homes and hospitals.

The world's first case appeared in Foshan, Guangdong Province in November 2002 and quickly became an epidemic. November 2002 On 5 August 2003, 8422 clinically diagnosed cases and 916 deaths were reported from 29 countries. The average mortality rate of the reported cases was:

Severe Acute Respiratory Syndrome (SARS) is a highly contagious disease. The true symptoms are: acute onset, fever as the first symptom, body temperature is generally higher than 38 degrees, often persistent high fever, occasional chills, accompanied by headache, joint pain, muscle aches, fatigue, diarrhea, cough, mostly dry cough, less sputum, occasional bloody sputum, chest tightness, severe cases of rapid breathing, shortness of breath, or obvious respiratory distress.

Pulmonary signs are often subtle, and some patients may hear a small crackle.

Fever does not go away, cough, weakness.

Fever, increased body temperature, malaise, nausea.

SARS broke out on November 16, 2002 in Shunde, Guangdong.

SARS refers to infectious atypical pneumonia, which is an inflammation of the lungs caused by the SARS coronavirus, which is named severe acute respiratory syndrome by the World Health Organization.

In the summer of 2003, the number of infected people was declining and the disease was completely under control. End of SARS: On June 24, 2004, the World Health Organization (WHO) announced the lifting of the travel ban on Beijing, indicating the victory of Chinese mainland in the fight against SARS.

This is a global epidemic of infectious diseases, severe acute respiratory syndrome.
