Wuhan pneumonia resembles 70% of SARS

The nCoV virus is similar to the Corona virus that causes SARS, but the mortality rate is about 1% and progresses slowly while SARS dies 10%, progressing faster.

Dr. Tran Van Phuc, Green Po Hospital, said that the nCoV virus is 70% similar to the SARS virus in 2003 (both of them are Coronavirus family). The remaining 30% are genetic differences, along with the manifestations of the disease.

"However, it is now the initial stage of a new acute pneumonia, requiring more data to fully assess , " Dr. Phuc emphasized. In addition, nCoV is a Beta variant of the virus, making it easier to spread from person to person. In particular, corona virus weakens when the temperature is above 20 degrees Celsius, especially above 25 degrees and high humidity conditions. If the humidity is high, good ventilation will limit the spread.

Symptoms of general coronary virus infection include runny nose, cough, sore throat, possible headache, fever and shortness of breath leading to severe acute respiratory distress syndrome, septic shock, metabolic acidosis, and coagulopathy. blood. For people with weak immune systems, the elderly and children, the likelihood of infection with Coronavirus is higher. The World Health Organization has assessed that the current situation of the disease is taking place mainly in China, so it has not reached the level of announcing the global emergency pandemic.

The cause of acute coronary pneumonia is the previously unknown strain of Corona, named nCoV, which causes respiratory infections. However, in Wuhan, China, Corona virus was found in bats, but the bats themselves could not transmit the disease to humans. Whether or not the cause of the outbreak comes from cats, civets, bats, snakes or other wildlife requires further evaluation, "as soon as possible to help prevent the source of the disease outbreak".

In the SARS-CoV outbreak in 2003, the Corona virus created a bat from a bat and then jumped to the civet, and the civet jumped to humans to cause disease. Therefore, in nCoV, bats can also be natural hosts, then create gene variants in the Beta position, then from bats to snakes as intermediate hosts, from snakes to humans in the butcher market. Huanan in Wuhan. In addition, the nCoV virus can be transmitted from person to person through close contact, coughing, sneezing and person-to-person transmission.

According to Dr. Phuc, in the near future, nCoV virus with a variant of the Beta position can greatly reduce the virulence but the possibility of infection is very high, especially from human to human. people.

"It means that the number of pneumonia patients and deaths is low, but the number of people infected with nCoV in the form of flu will greatly increase , " Dr Phuc explained.

Further, nCoV will become a common influenza virus and re-export on an annual basis. This is different from the highly virulent SARS-CoV, but the ability to spread the community is low so it is difficult to spread widely, easily destroyed after a 2003 epidemic and no longer coming back.

There is currently no effective drug to treat nCoV. The main treatment is still supportive therapy, symptomatic treatment, improving the resistance of the immune system. But, the detection of the Beta variant was a huge success, allowing us to discover proteins that help viruses invade cells. This is an opportunity for scientists to find vaccines specific to this strain.

The Ministry of Health has issued a Guideline for temporary surveillance and prevention of acute respiratory infections caused by new strain of corona nCoV virus. Accordingly, people with respiratory symptoms or suspected illnesses such as fever, cough, shortness of breath should not travel or to crowded places. Caregivers must take personal protective measures such as wearing a mask, eyeglasses, gloves, hats . washing hands with soap after each contact with the patient.

Supervising close contacts of patients, people sitting in the same row or before after two rows of seats on the same bus, train, plane, living in the same family . Hygienic ventilation, ventilation of houses, Wipe floors, door handles, and surfaces with soap or disinfectant. The sputum secretions of the patient must be thoroughly treated with a disinfectant containing 1.25 active chlorine .

For those who return from Wuhan City, Hubei Province, China or have close contact with a person with pneumonia in Wuhan City within 14 days if there are signs of fever, cough, shortness of breath, need go to the nearest health facility for timely consultation, examination and treatment.

Two hot numbers are published by the Ministry of Health to provide information about acute pneumonia caused by nCoV virus 0989671115, 0963851919. The Ministry recommends that people contact the Department of Preventive Medicine or the nearest health agency, if suspected pneumonia or pneumonia.

Acute pneumonia began in Wuhan on December 31, 2019 with 41 people hospitalized, then quickly spread to other cities and appeared in Thailand, Japan, South Korea and the United States. The cause of the disease is a previously unknown strain of the corona virus, named nCoV, which causes respiratory infections. By January 24, more than 830 Chinese people had acute pneumonia, 25 died, 8 cities including Wuhan, Huangjiang, Ngau Chau, Xich Bich, Tien Dao, Tiem Giang, Chi Giang and Loi Xuyen were beaten. Radiate internal and external.
