A person with immunity to coronavirus can be a carrier of infection, antibodies do not disappear, mortality will increase regardless of COVID-19, and Russians are advised to postpone trips abroad until spring. The editors of the Nizhegorodskaya Pravda website have collected the main news about the coronavirus, published today in TASS and RIA Novosti. The head of Rospotrebnadzor Anna Popova said that people with immunity to coronavirus can be carriers of the disease. “Immunity is not sterile, which means that the virus can live in the body despite the fact that a person does not get sick, does not give clinical manifestations himself. He lives on the mucous membrane, in other cells of the body,”explained Anna Popova. At the same time, scientists today do not know for sure whether such a carrier of the virus can infect. Anna Popova also emphasized that the antibodies obtained with coronavirus do not completely disappear. After recovery, their level decreases, but each encounter with the virus leaves an immune response. The required concentration of antibodies to resist infection has not yet been established. Currently, Russians are developing population immunity to the new infection. The head of Rospotrebnadzor added that 24 repeated cases of coronavirus infection have been recorded in the world, while in Russia at the moment there is not a single reliable confirmation of re-infection. According to Anna Popova, it is likely that preventive measures will have to be followed until the spring of 2021. And from trips to distant countries this year must be abandoned. Deputy Head of the Ministry of Health Oleg Gridnev at the coordination council of ombudsmen for human rights said that the mortality rate from coronavirus in Russia is 1.7%. In addition, excess mortality is predicted not due to COVID-19, but due to the fear of citizens to go to doctors during the epidemic. Since March, attendance at emergency departments has halved, and patients with chronic illnesses see doctors 30-50% less often. Today, Russian Prime Minister Mikhail Mishustin signed an order to include coronavirus vaccines in the list of vital drugs. According to the Cabinet of Ministers, the list will be officially replenished with the vaccine in early December. This solution will help ensure its availability. And in 2021, the list of drugs will be expanded to 788 drugs. By the way, according to the interim results of studies, the effectiveness of the Sputnik V vaccine exceeds 95% on the 42nd day after the administration of the first dose of the drug, provided that the patient receives the second. The Russian Direct Investment Fund clarified that now 40 thousand volunteers are participating in the third phase of testing. “As of November 24, during the Sputnik V survey, no unforeseen adverse events were detected. Some of the vaccinated had short-term adverse events, such as pain at the injection site, flu-like syndrome, including fever, weakness, fatigue, headache,”the Foundation noted. When the third phase of clinical trials of the vaccine is over, the Center. Gamalei will provide access to the full test report. In addition, RDIF and its partners have launched production of the Sputnik V dry form of vaccine, which is stored at temperatures from +2 to +8 degrees Celsius. This will allow it to be distributed in international markets and in hard-to-reach regions, including areas with tropical climates. Experts have previously complained that vaccines under development must be kept at temperatures as low as possible in conventional pharmacies.At the same time, specialists from the University of Geneva in Switzerland have found drugs that can block the penetration of SARS-CoV-2 viruses into cells. The study published in the journal Chemical Science led to the discovery of inhibitors that can do this 500 times more efficiently than the previously used Ellman's reagent. Recall that according to the head of Rospotrebnadzor Anna Popova, the Nizhny Novgorod region was able to stop the increase in the incidence of coronavirus. The editors of the Nizhegorodskaya Pravda website have compiled an online map of the distribution of Covid-19 in cities and districts of the Nizhny Novgorod region. Chronicle of coronavirus in the region - in a separate story.
