To date, a person has not been isolated for 90 days after diagnosis by PCR or antigen test (in both cases, a swab from the patient’s nasopharynx) or after vaccination with a full vaccination schedule if the person had a high risk exposure to a person. diagnosed with coronavirus infection.
According to the recently approved algorithm, the result of a serological antibody test (based on a blood sample) will be evaluated when deciding on the isolation procedure after a high-risk contact. A response to the serological test will be required if more than 90 days have elapsed since the illness or vaccination and the person has been exposed to a high-risk contact, as well as in all other cases after a high-risk contact, for For example, if the human diagnosis of coronavirus has not been confirmed by laboratory tests.
The Ministry of Health recalls that an algorithm was approved even earlier that will continue to be applied to certain groups of people exposed to high-risk contacts. These groups include people who work and receive treatment services, supportive care and nursing services, people who receive supportive treatment and nursing services, employees and residents of welfare institutions, prison employees and detainees. This algorithm also applies to people with immunosuppression, that is, suppression of the immunity of the human body.
According to him, if a person from these groups is at high risk of exposure, it is evaluated if the person has a valid antibody test for 60 days, and then isolation is decided. If the test is positive, that is, the test shows that the person already has immunity that protects against infections and diseases, the person comes out of isolation. If the test is negative, that is, it does not show established immunity, isolation is required. If there is no test, you must take it.
It is important to note that the new regime stipulates that if a positive serological antibody test is performed within 60 days before January 25 when isolating a person exposed to COVID-19, the person will need to contact the tester to avoid isolation. . a document certifying that the test meets all the criteria. For the test to meet the criteria set by the specialists, this is necessary because some of the tests on the market so far have been suitable for isolation and some have not. The lab will know what manufacturer’s tests are used and what the specifications of that test are. If the person does not have such a document, it will be necessary to repeat the investigation. According to expert recommendations of January 25. no additional testing will be required once the new testing requirements take effect.
The decision to isolate a person after having had a high-risk exposure is made by specialists from the National Center for Public Health.
The Ministry of Health recalls that a serological antibody test is designed to detect the response of the human immune system to a viral infection. It is best used to determine if a person has already had COVID-19 and has specific immunity to the virus after they have been vaccinated or vaccinated.
