Rospotrebnadzor said that the omicron strain causes pneumonia faster

The new strain of CORONAVIRUS, omicron, descends into the lungs faster than others, causing pneumonia in three to five days. This was reported to Izvestia by a virologist and immunologist, HEAD of the Yekaterinburg Research Institute of Viral Infections of the Vector Center of Rospotrebnadzor Alexander Semenov.

“What is bad about the Omicron strain is that, just like Delta, it is more tropic, that is, it is capable of interacting with the epithelium of the lungs and lower respiratory tract. Therefore, "omicron" descends into the lungs faster, causing pneumonia. This is very worrying,” the expert said.

According to Semyonov, when infected with the previous strains, it took up to 11 days from the moment of infection to the onset of pneumonia, but today this happens already in three to five days.

The expert also noted that the effectiveness of vaccines against the omicron strain may decrease, but citizens will still remain protected. “According to some data, the efficiency is reduced, but not more than by 40%, not at times. According to other data, it decreases even less. What is a decrease in efficiency even by 40%? This means that people with an antibody titer of not 500 BAU, but 700 BAU will be protected against the Omicron strain. But after vaccination, it could be 1.5 thousand BAU or 2 thousand BAU,” he specified.

At the end of November, British scientists reported the emergence of a new strain of coronavirus, which was later given the name "omicron". The first cases of infection were reported in South Africa and Botswana. Later, this option spread to the UK, Germany, the Netherlands, Australia, the usa and other countries. The World HEALTH Organization (WHO) indicated that the number of mutations of "omicron" is "unprecedented" and it may be more infectious than previously discovered strains.

After that, many countries restricted flights from South African countries, including RUSSIA .. So, from November 28, entry into Russia from South Africa, Tanzania, Hong Kong, Botswana, Lesotho, Namibia, Zimbabwe, Mozambique, Madagascar and Eswatini has been restricted. In addition, all arrivals from South Africa and neighboring countries are sent to a two-week quarantine.

Earlier, WHO expert Maria van Kerkhove said that so far there is a tendency for a milder course of the disease in those infected with a new strain of coronavirus, but experts have too little data for a definite answer. Professor of the National Research Center of Epidemiology and Microbiology named after Gamaleya Anatoly Altshtein also said that so far there is no reason to believe that the omicron strain causes a more severe course of the disease. “All the people from whom this virus was isolated, they suffered this coronavirus infection very easily,” he said.
