Sống chung Covid-19 như thế nào?

Covid-19 pandemic: The severe medical crisis Covid-19 is the first pandemic caused by a new strain of corona virus. The World Health Organization (WHO) admits that, despite the race against time to study the SARS-CoV-2 virus, we still have many unknowns about this new virus strain. Covid-19 is a once-in-a-hundred-year health crisis, and its effects are likely to last for decades. Through the lens called Covid-19, humanity seems to be witnessing a world turned upside down. SARS-CoV-2 has a super small size that cannot be seen with the naked eye, but it can attack all aspects of life - society. WHO Director-General Tedros Adhanom Ghebreyesus warned: “This is a dangerous enemy combined with a contagion of terrifying characteristics: it spreads quickly and is deadly. It can work in the dark, It spreads silently if we don't pay attention, then it suddenly explodes if we're not ready to deal with it." The SARS-CoV-2 virus spreads very quickly. People infected with the virus may not show symptoms of the disease, so it is easy to spread the virus to others. Covid-19 pushed modern health systems across the globe into overload, causing millions of doctors and medical staff to become ill and had to signal the government for help. Vietnam with the spirit of "fighting the epidemic like fighting the enemy" is promoting measures to prevent, control and control the spread of the disease. Therefore, in addition to strictly following the directives of the Prime Minister and the Ministry of Health, early detection of infections through virus detection tests for timely, quick and concise isolation is extremely necessary. . Who needs to be tested for Covid-19 People who need to perform a rapid test for Covid-19 (SARS-Cov-2 virus) are those who have at least one of the symptoms of a viral acute respiratory infection SARS-CoV-2 causes such as fever, cough, difficulty breathing, sore throat, pneumonia and has one of the following epidemiological factors: Having close contact (within 2 meters) with a person infected with Covid-19 or people suspected of being infected with Covid-19, including: people living in the same house, working in the same room, traveling, working, sitting in the same row and front and back of two rows of seats on vehicles, etc. Returning from the "regions" epidemic" was recorded by WHO with a case of Covid-19 within 21 days of entry (in centralized isolation). Return from epidemic areas in Vietnam within 21 days before the onset of symptoms. Covid-19 patient during treatment. As directed by a doctor/investigator/medical agency. If you are among the subjects that are susceptible to Covid-19 above, you should immediately contact a health facility to be tested for Covid-19 soon. High precision Genuine modern equipment High professional skills Safe process Reasonable cost All these factors aim to bring the best value to customers during the period of epidemic increasing in level dangerous and rapidly spreading.

Popular on-demand Covid-19 testing services Molecular testing Antibody testing Definition Realtime molecular biology testing RT-PCR is a test method that determines the presence of the virus through detection of genetic material of the SARS-CoV-2 virus, this is a highly accurate method. As recommended by the CDC, the RT-PCR test is the "gold standard" for diagnosing Covid-19. An antibody test (serology) is a blood test that looks for the virus indirectly through the determination of antibodies in the blood. Antibodies are special proteins (IgM, IgG) that the body produces to fight infections. Normally, after an infection, it takes a while for the body to produce detectable antibodies in the blood. Performing the test can effectively detect people who have been infected with the virus before. However, it is not very effective in detecting new infections. Procedure for taking samples for testing Step 1: Prepare before taking samples. Healthcare workers performing sampling should ensure biosafety principles for infectious diseases, including: Wearing the right quality and proper protective gear. Wear N95 respirator and helmet, goggles, face shield. Wear 2 layers of medical gloves. Perform disinfection and do not wear protective gear out of the sampling area. Step 2: Take the specimen. Medical staff taking samples include: – Respiratory fluid: Using a sample stick to collect samples of upper and lower respiratory tract fluid: Upper respiratory tract fluid: Throat fluid, nasopharyngeal fluid, throat gargle. Lower respiratory tract fluid: Sputum, alveolar fluid, endotracheal fluid, pleural fluid, lung tissue, bronchi, alveoli. – Put the 2 sample strips that have been taken into the same tube of available virus transport medium. Step 3: Preserve the sample. Once the sample is collected, the specimen should be sent to the laboratory as soon as possible. Samples are stored at 2 – 8oC and transported to the laboratory 48 hours before sampling. Samples are stored immediately at -70°C if transit time is expected to exceed 48 hours. Do not store samples at -20°C or in the freezer compartment. Whole blood samples can be stored for up to 5 days at 2-8°C. Step 4: Pack and transport samples to the laboratory. Tighten the specimen type cap and cover with paraffin paper, wrapping each specimen type with blotting paper. Place the sample in the sample carrier bag. Wrap the transport bag with absorbent paper, cotton soaked in water containing disinfectant (Cloramin B...). Then place the specimen pack in the second plastic bag and tie it tightly. Close the specimen collection sheets into the final plastic bag, tie it tightly and transfer it to a cold thermos, with the logo of biological specimens painted on the outside, and then proceed to transport. Currently, there are two techniques to find antibodies: ELISA technique helps to quantify the concentration of IgM and IgG antibodies in the blood, On average, it takes 1-5 hours to get blood antibody results. Immunochromatographic technique (rapid test or rapid test): qualitative antibody, similar to pregnancy test. This technique is simple, low cost, fast results. It only takes 15-20 minutes to have results with or without antibodies. Results time RT-PCR test can give results in about 4-6 hours in the laboratory. However, it takes about 1 day to return the results. Results can help doctors predict disease progression, as well as evaluate the effectiveness of therapy. Made faster with results in just 15-20 minutes. Number of Tests for Accurate Results How many tests are needed if the first test is NEGATIVE in order to be able to say that the person is not infected or “virus-free”. This is very difficult to confirm. need further research and update according to the guidelines for diagnosis, treatment and surveillance at health facilities and in the community depending on the actual situation in the country, region, territory and each locality. With antibody detection tests such as rapid tests, test results are preliminary and screening only. The main purpose of this test is to detect suspected cases early and to conduct medical isolation if necessary. In many cases, patients who are tested negative 2-3 times can still have the disease. In contrast, when the sample is taken between days 5 and 6, the positive rate is higher if the person already has the disease. Significance of the results The test can detect cases of SARS-CoV-2 infection at the end of the incubation period (1-2 days before the first symptoms) and the full-blown phase. Positive result: The test subject is determined to be infected with the virus and has the ability to spread and transmit the virus to others. Negative result: the subject was determined not to be infected with SARS-CoV-2 virus at the time of sampling. A positive test result shows that you have antibodies from infection with the virus that causes Covid-19. However, there is still the possibility that that positive test result is a PASSIVE POSITIVE. After that, it is necessary to take samples from the pharynx, pharynx and sputum to perform a confirmatory test for Covid-19. At the same time, conduct medical isolation of the patient. Negative result: subject was not infected with SARS-CoV-2 virus at the time of sample collection. However, this test has a HIGH rate of NEGATIVE NEGATIVE, with about half of NEGATIVE results being incorrect. However, testers continue to monitor their health status and isolate for 21 days. The rapid test can be performed again after 5-7 days. The most popular method of testing for Covid-19 (SARS-Cov-2 rapid test) today RT-PCR (Real-Time PCR) test with confirmatory results and a screening-significant rapid test is Two methods of rapid testing for Covid-19 have now been approved by the Ministry of Health to limit the spread of the disease to the community and minimize the death rate. “Depending on the stage of the disease, clinical course and economic resources, we use one or both of these tests for patients. Each test has its own advantages and disadvantages”, said Dr. Truong Huu Khanh, 1. RT-PCR test This method allows to determine the presence of the virus in the body, is usually indicated for a group of people exposed for 21 days or to monitor the treatment of patients who have been diagnosed with Covid-19. In addition, in the early days of infection, the virus did not multiply enough and did not appear much in the respiratory tract. Then the test result may be negative even though the body has been infected. If the sampling technique, the technique of preserving the patient sample is not guaranteed, it will also give inaccurate test results. Or, after 21 days of infection, the test can go from positive to negative for cases that clear up on their own or get cured. It should also be added that the RT-PCR test must be certified by the Ministry of Health as having the capacity to confirm the SARS-CoV-2 virus. Accordingly, these facilities must fully meet the standard conditions of rooms, machinery, trained testing staff, comply with the correct process, Reasonable prices and guaranteed results on time. 2. Test for anti-viral antibodies in the blood (rapid test) This test allows to determine if the patient is infected or previously exposed to the virus, and if so, there will be antibodies against SARS in the blood. -CoV-2. Rapid test method is usually indicated for cases after 2 weeks of exposure, enough time for the body to produce antibodies. The technique is simple, costs little, gives quick results, but if done early in the first 2 weeks when the body has not yet produced antibodies, the results will still be negative even though the body has been infected with Covid-19. In the positive case, it is also not possible to determine whether antibodies were produced during recent or past infection. At that time, additional RT-PCR testing should be performed to have an accurate confirmation. Besides, Rapid testing is also to determine if the body has antibodies against the virus. However, antibodies usually form 2 weeks after infection. Therefore, if the rapid test is positive and the RT-PCR test is negative, it can be explained that the person has been exposed to the source of infection or has been infected and the ability to infect others is no longer possible. Conversely, if the rapid test is negative and the RT-PCR test is positive, then it is likely that the person has been infected within the last few days (<7 days) and the antibodies have not yet formed in the blood. Covid-19 rapid test method “Do not use rapid antibody test to confirm, because the nature of the test is used to detect antibodies of people who have been infected and usually recovered, not to detect new infected people. If positive, the rapid test does not reflect that the person has antigens in the body. And if it was infected before, the consequences of spreading the virus have already happened," emphasized doctor Truong Huu Khanh. In addition, rapid testing is not suitable for early testing because most are negative. A negative result also does not reflect whether the person has the virus in their body. It is not surprising that many cases after antibody test showed NEGATIVE results, then retested by RT-PCR gave POSITIVE results. People who receive a negative result of the rapid test think that they are not infected with the virus, no longer carry the virus, causing subjective psychology. Currently, the RT-PCR test is still mainstream, detecting whether the oropharynx has the virus or not. However, the RT-PCR molecular test does not show whether a person has immunity from a past infection with Covid-19 or has never been infected. The combination of molecular testing RT-PCR and rapid testing can show progression through the stages of the disease more specifically. Therefore, on a case-by-case basis, to conduct an appropriate Covid (Sars-Cov-2) rapid test service such as: Firstly, to monitor treatment results in people who have been infected with SARS-CoV-2 after Are there antibodies present? Are there still antibodies? This is important to adjust medication, change regimen accordingly. Second, to investigate the epidemiology in the community to see if people in that area were previously infected with SARS-CoV-2? This is necessary to know the risk of infection in the locality where you live, the population, the season, etc., thereby developing an epidemic prevention strategy. What to do after Sars-Cov-2 test results After conducting a quick Covid-19 test, if the result is positive: The test subject is determined to be infected with the virus and has the ability to spread and transmit the virus to others. Accordingly, people at risk of contracting the SARS-CoV-2 virus (with a health insurance card) when returning from an "epidemic area" or having close contact with a positive patient will be entitled to free diagnostic tests for the disease. at units licensed to carry out tests to confirm the diagnosis of Covid-19 nationwide. If the result is negative, health insurance will cover the full cost of the test. 3. Can I have breakfast for a Covid-19 test? In many cases, patients are asked to fast for at least 4-6 hours when taking blood tests or not eating breakfast after getting up. The reason for this is that after eating, the nutrients in the food will be converted into glucose, The intestines will absorb and convert it into energy for the body. This can cause high blood fat or sugar levels and affect the accuracy of the test results. 4. Is the Covid-19 rapid test covered by insurance? The current worldwide health crisis caused by the Covid-19 pandemic further underscores the importance of universal health care coverage of the health care system in each country. It is health care coverage that is critical to the resilience of each country's health systems to health crises caused by epidemics. For patients after discharge, continue to isolate for 21 days, test 3 times including: 1st time on 5-7 days; 2nd time on 12-14 days; 3rd time on the 21st day during home isolation. For people in close contact with an infected person, Re-positive people are isolated in concentrated isolation. Test at least 2 times right after isolation (1st day), 2nd time before completing isolation period (21st day). Sampling as soon as symptoms are suspected. Foreigners entering Vietnam for short-term work and isolation are allowed to move according to the declared schedule. Test 1 at least 3 times on the first day, take samples every 2 days during your stay in Vietnam and 1 day before leaving Vietnam, and collect samples when you have suspicious symptoms. Particularly, those entering the country who work for more than 21 days will be isolated in concentrated isolation, tested for the first time upon returning to the concentrated isolation place, the second time on the 14th day and the third time on the 20th. Explain the negative test for the first time. then after 3-4 tests, it was positive, from a medical perspective, Assoc. Tam Anh Hanoi General Hospital said: “Firstly, the patient is infected with Covid-19 but the virus has not multiplied enough to give a positive result, which is why people at risk of Covid-19 infection must be isolated. enough for 21 days. Second, the test results depend a lot on the technique, sampling time and the process of transporting and preserving samples. In short, if a person travels through an epidemic area or has close contact with an infected person, self-isolation and monitoring for 21 days is the most important thing. Prioritize testing for people with respiratory symptoms to detect cases for timely treatment. Early testing when there are no clinical symptoms has little value, causes subjective psychology, is not isolated and can become a source of infection for the community if they are positive days later. People returning from epidemic areas should not rush to get tested immediately with the mentality of "for peace of mind". Should notify local health to be on the watch list and be instructed to self-isolate for 21 days. During the isolation period, if you have symptoms of fever, cough, sore throat, diarrhea, etc., you should notify your doctor for early testing. Other cases will be tested on days 20-21 to confirm negative and ensure safety before re-entering the community. incentives when testing for covid-19 at his center Tam Anh General Hospital is ready with modern facilities, machines, biological products, a strong medical staff and necessary conditions to carry out the test. rapid, safe, accurate test samples at a reasonable cost to protect themselves and the community from the attack of the Covid-19 epidemic wave. The team of doctors and laboratory technicians are trained in the process, improve expertise in molecular biology testing to test for Covid-19 with high accuracy, no errors. The testing team adheres to the correct, meticulous and accurate process at all stages: recording epidemiological records, personal information, taking samples, extracting genetic material, running the machine... Especially, all The testing process at the Testing Center, Tam Anh General Hospital is carried out and strictly controlled by the quality control system ISO 15189:2012 recognized by the Vietnam Laboratory System - VILAS. Not only testing for Covid-19 for individuals, families and businesses who come to test directly, Tam Anh General Hospital also deploys a service to home/office to take samples with the number of samples tested from 100 people or more. Especially, The hospital also provides Covid-19 testing service for customers who want to leave the country with a "negative passport" (Test result) with the customer's passport number instead of just the ID/CCCD number. To use the Covid-19 screening test service, Customers can do the following ways: You can see where the method of Covid-19 diagnosis and testing is, how much it costs to help detect SARS-CoV-2 is very necessary in the current context. Therefore, every citizen who is suspected of being infected with Covid-19 should be tested for early detection and timely zoning and isolation measures to limit the spread of the disease. Currently, the Covid-19 rapid test service for early detection of Covid-19 has been deployed at many medical facilities across the country.
