Ho Chi Minh CityF0 or people with symptoms should not be tested continuously because it is unnecessarily expensive and causes anxiety, according to experts.
Ms. Ha Anh, who lives in Go Vap district, does a quick test twice a week for a family of four. She explained that “because neighbors and colleagues around were infected with Covid-19 in turn, tested for peace of mind”.
For four days now, she has symptoms of cough and sore throat. Every day she does a quick test for the whole family, but “doesn’t understand why there’s always one line”. In total, a month ago, her family spent more than 5 million VND buying test kits. “Test is also worried, but not test is also worried,” said Ms. Ha Anh.
Ms. Thu, from Phu Nhuan district, also tests herself regularly. When she was found to be positive for nCoV, she was even more impatient, testing many times “to see when it is negative”. Her family spent more than 10 million VND to buy the kit, not to mention the money for masks, medicine, and nutritious food.
Many people also have similar anxiety, the more they test, the more insecure the results “don’t know if it’s accurate”. The story of testing one line, two lines, dark lines, and light lines is widely discussed in F0 treatment groups, in the context of the current rapidly increasing number of cases.
Doctor Nguyen Minh Tien, deputy director of the City Children’s Hospital, said that frequent testing causes unnecessary costs and psychological effects. Doctors recommend that people without symptoms do not need to be tested.
According to the guidance of the Ministry of Health, people with symptoms such as cough, fever, sore throat, runny nose, should be tested. If positive, self-isolate at home, contact a doctor for advice. Those who have had enough vaccines, 5 or 7 days after testing positive, retest, negative results can go to school or work. If you are still positive, you will need to wait for 10 days, no need to re-test, you can complete isolation because there is no longer the ability to infect. People who have not had enough vaccines, on the 10th day since being positive, need to be tested again, if the results are negative, they will complete isolation. copper.
With children, the virus is usually eliminated faster, most children can be negative three days, so a quick test can be done on the third or fifth day. If the third or fifth day is still positive, on day 7 be able to complete isolation without testing with vaccinated children; Test again quickly if the child has not been vaccinated.
“People with symptoms (if the test is negative) should not be re-tested often,” said Dr. Tien. In this case, the negative could be due to other illnesses such as viral fever, flu, not Covid-19.
To eliminate the risk of disease and spread, patients can self-treat symptoms, monitor their health, isolate at home or go to work, keep a distance from people around, and adhere to 5K. Treatment of symptoms by reducing fever, herbal cough medicine, vitamins, rinsing the nose, gargling with physiological saline, eating, resting to strengthen the resistance to fight the disease.
Particularly for elderly people with underlying diseases, if they have symptoms, have epidemiological contact but the rapid test is negative, PCR test can be performed to identify the disease, promptly take antiviral drug molnupiravir under the advice of a doctor. doctor (if indicated). Some cases of rapid test were negative but PCR was positive due to sensitivity, specificity of rapid test kit, self-sampling operation, sample reading time.
With the same opinion that rapid testing or costly PCR should not be abused, Dr. Truong Huu Khanh, consultant of Infection block, Children’s Hospital 1, said that “testing back and forth” considers one line or two lines not as important as one line. monitor symptoms when facing strains of Omicron. “When there are suspected symptoms, even one line or two lines will treat the same and prevent infecting others, if you go anywhere, do 5K,” the doctor said. If the fever is higher than 48 hours, seek medical attention because of the possibility of dengue fever. If symptoms are severe, seek medical attention.
Besides, according to Dr. Khanh, when it is positive, people do not worry about the blurred lines, the bold lines because they have no prognostic value for severe disease, mild disease, only showing the ability to spread more or less, sometimes the degree of infection. The intensity of the line is also due to the place where the sample is swiped. In addition, there is no need to worry when the symptoms disappear very quickly, but two lines for many days, because it is important that the symptoms disappear quickly.
In addition, do not rush to rely on rapid tests or PCR to be sure that you are completely free of the virus after 5-7 days. “10 days without testing, always wear a mask, don’t gather so that it is less likely to infect others, maybe it’s safer than someone who just 7 days after seeing a line rush to the street without wearing a mask. If you are careful, especially, If there are elderly people in the house, have underlying diseases, or a working environment with many people, after the end of the 7 days of isolation, 5K for a few more days”, Mr. Khanh emphasized.
