Differences between the chain of nCoV infections in HCMC and Da Nang outbreaks


Health experts believe that the chain of infections in Ho Chi Minh City is well controlled, small-scale, not as serious as the Da Nang epidemic.

The two waves are nearly four months apart. On July 25, “patient 416”, male, 57 years old, was the first case in Da Nang, starting the second wave of Covid-19. This case then terminated the 99-day chain of not recording public infection. In Ho Chi Minh City, on November 28, “patient 1342”, the 28-year-old male flight attendant, ended Ho Chi Minh City’s 120 days and the nation’s 88 days without community infection.

Master, doctor Nguyen Tran Nam, Head of the Department of Infections, Children’s Hospital City, Ho Chi Minh City, said that the biggest difference between the translation from Da Nang and the infection chain in Ho Chi Minh City this time is in nature.

Determine F0, speed of zoning, isolation

In Da Nang, although the health sector has been screened and thoroughly investigated, the source of infection cannot be traced (F0). F0 cannot be identified, making it difficult to localize and stamp out the epidemic. In addition, nCoV attacks a hospital, where there are many elderly patients, many serious chronic illnesses, causing severe human damage.

These cases in HCM City, F0 were detected quickly and early. As soon as “patient 1342” was positive for nCoV, on November 28, the authorities determined that he was infected from “patient 1325”, the same airline’s flight attendant, on the return flight from Romania. . Obviously the source of infection, finding F0, the health sector does not need to trace back, but focuses on exploiting patient schedules. More than 2,500 F1 and F2 were zoned, isolated and sampled for testing.

In four days, the “patients 1347”, 1348 and 1349 respectively were discovered through zoning, testing, completely without symptoms. By the evening of 4/12, no other community infections have been recorded. In addition, the patients are young, in good health, have no symptoms, and have a low risk of death.

Coordinate epidemic stamping, hospital protection

Since July, Da Nang has been considered the largest outbreak in Vietnam, spreading to many provinces. More than a million people must be isolated from society, closing down the whole city of Da Nang. It took two months (from July 25 to September 25) for Danang to return to normal function. When the last patient with Covid-19 was discharged from the hospital, the city controlled the risk of infection. According to statistics of the Ministry of Health, since the date of recording “patient 416”, there have appeared more than 550 cases related to Da Nang, 35 people died from Covid-19 with severe chronic background disease.

Dr. Nam said that, having “practiced many games” before, plus lessons learned from Da Nang, for this infection chain, the agencies in Ho Chi Minh City coordinated smoothly, well and quickly. Therefore, minimizing the scale of infection, suppressing the epidemic, not having to block out a large area. The city continues to accumulate forces to trace carefully, to avoid omitting the dangerous object.

“Hospitals in Ho Chi Minh City are still very safe. Particularly for Children’s Hospital in Ho Chi Minh City is always ready to fight in all situations. When receiving 1348 patients, we still ensure absolute safety for other patients, “said Dr. Nam.

Lessons from the chain of infections in HCMC

Associate Professor, Dr. Nguyen Viet Nhung, President of the Vietnam Lung Association, said that although the new infection chain in Ho Chi Minh City has quickly identified F0, it is not as difficult as Da Nang, however, this is the post. learning is “too expensive”, threatens public health and costs the health sector.

According to Mr. Nhung, the epidemic in Ho Chi Minh City is under good control, the chance of spreading is low but absolutely not subjective, as the Covid-19 epidemic in the world continues to be complicated. The risk of an epidemic outbreak is still constant, if measures to prevent and control are not strictly taken.

“We have to tighten and tighter measures to ensure the safety of the people, at the same time investigating and tracing, finding all places of travel and people having contact with patients, quarantine practice. middle case close contact “, Dr. Nhung emphasized.

People are advised to absolutely not neglect, need to monitor the location of positive patients to prevent risks. If it is F1, promptly contact local health care for centralized isolation. If it is F2, actively inform and monitor the health and test results of F1.

Cases of home isolation should comply with home isolation 14 days from the last day of travel to the above areas and instructions for self-isolation at home by the Ministry of Health. Only leave home when necessary, wear a mask when leaving home, at work, study or activities. Do not go to places where people gather. Limit contact, not close contact with other people. Wash your hands often with clean water and soap or a quick hand sanitizer.

People monitor their own health, when there are signs of suspicion of Covid-19 such as fever, cough, shortness of breath, etc., they must immediately report to local health or go to the district hospital immediately examination and testing.

Talking to VnExpress on December 3, Mr. Tran Dac Phu, Senior Advisor of the Vietnam Public Health Event Center, also said that “translation in Ho Chi Minh City is like a small fire”, early detection. can be completely extinguished.
