What kind of disease is SARS

It is a highly contagious disease.

It is a global infectious disease epidemic that occurred in Guangdong, China, in 2002, spread to Southeast Asia and the world, and was gradually eliminated until mid-2003.

As of August 16, 2003, Chinese mainland has reported a total of 5,327 clinically diagnosed cases of SARS, 4,959 cases discharged, and 349 deaths (another 19 deaths from other diseases, not included in the number of SARS deaths).

Hong Kong: 1,755 cases, 300 deaths; Taiwan: 665 cases, 180 deaths; Canada: 251 cases, 41 deaths; Singapore: 238 cases, 33 deaths; Vietnam: 63 cases, 5 deaths.

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.

Answer]: E analysis: According to whether the clinical manifestations are typical or not, pneumonia can be divided into two categories:

Typical pneumonia includes pneumonia caused by Streptococcus pneumoniae, Staphylococcus aureus, Klebsiella pneumoniae, Haemophilus influenzae, and Escherichia coli. Atypical pneumonia includes pneumonia caused by Mycoplasma pneumoniae, Chlamydia fluid, Legionella pneumophila, and certain viruses (hantavirus, coronavirus).

1.Early Presentation:

1-7 days at the beginning of illness.

Symptoms show fever, body temperature is generally greater than 38 degrees, most patients will have headache, joint muscle pain, weakness and other symptoms, a few patients have dry cough, chest pain, diarrhea and other symptoms. Lung shadows on chest x-ray appear on average about four days after the onset of illness, and more than 95% of patients have positive changes within seven days of the course of the disease.

2.Interim Performance:

The 8th to 14th day of onset.

Fever and symptoms of infection and poisoning persist, and pulmonary lesions worsen, presenting with chest tightness, shortness of breath, and dyspnea, especially after exertion.

Chest x-ray shows that lung opacities develop rapidly and are often lobular lesions. A small number of patients, 10% to 15% develop life-threatening respiratory distress (ARDS).

3.Convalescent Performance:

The body temperature gradually decreases, the clinical symptoms are relieved, the lung lesions begin to absorb, and most patients can be discharged after about two weeks of recovery.

A small number of critically ill patients may have restrictive ventilatory dysfunction and decreased pulmonary diffusion function for a considerable period of time, but most recover gradually within 2 to 3 months of discharge.

Precautions. 1. Ventilation is often used indoors to maintain air circulation.

2. According to the weather changes, pay attention to cold protection and warmth, often go outdoors, participate in exercise, and enhance their ability to resist diseases.

3. Pay attention to a balanced diet, exercise regularly, get enough rest, reduce stress and avoid smoking.

4. Wear a mask when in contact with people with respiratory infectious diseases, and pay attention to hand cleaning and disinfection.

5. Avoid contact with suspicious animals and birds.

Atypical pneumonia (SARS) refers to pneumonia in which the exact source of the disease has not been identified and the causative agent has not yet been identified. At present, it specifically refers to the atypical pneumonia epidemic in China in 2003.

Atypical pneumonia is relative to typical pneumonia, which is usually caused by common bacteria such as pneumococcus. Symptoms are typical, such as fever, chest pain, cough, sputum production, etc., laboratory tests show increased blood white blood cells, and antibiotics** are effective. SARS itself is not a newly discovered disease, it is mostly caused by viruses, mycoplasma, chlamydia, rickettsial and other pathogens, symptoms, lung signs, blood test results are not as obvious as typical pneumonia infection, some viral pneumonia antibiotics are ineffective.

Atypical pneumonia refers to a group of diseases caused by the atypical pathogens described above, rather than a definitive diagnosis. Most people with SARS develop symptoms 4 days after infection, with fever as the first symptom and a body temperature of 39 or more persisting for several days. Some people may have headache, chills, fatigue, joint pain, body aches, and diarrhea.

Respiratory symptoms are obvious, dry cough, less phlegm, occasionally bloody sputum, severe 5 days later, dyspnea symptoms such as rapid breathing, breathlessness, and respiratory failure in a very few patients, such as delay in diagnosis and treatment can cause death.

Atypical pneumonia, also known as atypical pneumonia, is an umbrella term that refers to all pneumonitas caused by an unknown pathogen.

These pathogens can be non-bacterial microorganisms such as coronavirus, Mycoplasma pneumoniae, Chlamydia pneumoniae, etc., that is, the symptoms of pneumonia that are not caused by bacteria, are called atypical pneumonia. However, the symptoms of pneumonia caused by Legionella are sometimes referred to as atypical pneumonia.

It seems that as long as it is different from the pneumonia caused by the usual common pathogens of pneumonia, it is called atypical pneumonia.
