Covid-19 is different from SARS
On the morning of 4/5, our country registered 271 cases of Covid-19, of which 18 days did not register cases outside the community. The two most recent cases were two cases of invasive cases, with people returning from foreign countries immediately upon entry.
Currently, Vietnam has good control of the epidemic situation, but the epidemic in the world is still very complicated.
According to Associate Professor Dr. Tran Dac Phu, Senior Advisor, Vietnam Center for Emergency Events, Covid-19 is transmitted by inhalation, just like old SARS. However, most patients with SARS are in critical condition and require hospitalization. We handle, treat, isolate all cases of disease. SARS does not spread as much as the flu or as Covid-19. Therefore, the disease only exists in some countries, when we manage it, the epidemic disappears, it only lasts a few months.
In contrast, the Covid-19 epidemic has many asymptomatic cases, mild fever, cough like the flu, and can exist in the community and spread. Due to this nature, the epidemic has a prolonged spread, which we cannot face.
According to Dr. Phu, Covid-19 is different from the flu. Most cases of the flu are mild, with few deaths. It exists in the community, causes a high incidence, and progresses to infection in the community, giving people immunity. Cases can increase and decrease each year, but they do not cause a collapse of the health system during treatment.
Covid-19 has mild cases, the ability to spread is difficult to control. Because it is difficult to control, it has a long-lasting effect.
“To build community immunity, it is very difficult for the disease to remain at a level acceptable to the community. We can accept influenza cases in the community to increase human immunity, because the number of cases may be high but death is not great. With the SARS-CoV-2 virus, it can’t be that way, “emphasized Dr. Phu.
No response when translation ends!
Experts also said that the Covid-19 outbreak could go on, without a vaccine, it is not known how long it will last. Currently, no country, experts dare to confirm that Covid-19 will become a seasonal flu or worse than SARS.
“Right now, we have some understanding of SARS-Cov-2 like this and the Vietnam prevention method is still how to prevent, detect, isolate and quarantine. I’m still saying it’s like a little fire, so don’t let it explode in a big fire, “said Dr. Phu.
According to the associate professor of Phu, we work, live, study, do business, but we also have to ensure good prevention of epidemics and people’s health, especially to avoid a large number of cases. A high incidence is likely to cause a large death. Therefore, detection of the first case, isolation, zoning, and quarantine for good is very important. That is the responsibility of each locality in the country.
The risk of an epidemic in our country remains high.
“We have managed to control the disease, but we still determine that the risk of epidemics in Vietnam remains high. We have implemented a social gap, we have prevented the outbreak from spreading in the community, but the risk remains high because the epidemic in the world is still complicated. Many countries are also struggling with the disease situation, the number of cases remains thousands of cases daily, even a few hundred deaths, “said Dr. Phu.
According to him, the risk of epidemic outbreaks in the driveway is still possible. Furthermore, we do not guarantee that there will be no more than 100% of cases in the community despite the social gap.
With an outbreak when detecting a positive case, we made a block. All positive cases, close contact cases called F1 are brought into isolation. With the rest of us, we take all measures to do so if there are still those who are carriers of the disease, they will not have contact with healthy people, the opportunity to have little contact. The chances of good people coming into contact with the sick are also slim.
After 28 days of blockage, symptomatic patient cases were transferred to the hospital. Assuming there are positive cases without symptoms, the 28 days will disappear on their own, without being able to spread the disease.
But in the community, no matter how socially displaced, no country can avoid 100% of a potentially contagious case of contact with an uninfected person.
“We don’t know in the community who are still germs. Germs may still be spread. Therefore, the risk of disease is still possible, “emphasized Dr. Phu.
People still need to comply with disease prevention measures that include: wearing masks; do not gather in large quantities; Do not go out when not necessary, especially the elderly, people with underlying illnesses; avoid close contact; wash your hands often with soap or an antiseptic solution; Medical statement …
