One of the main topics of the OpenBio complex of events held last week was the coronavirus pandemic: statistical data on the current situation were announced, prospects in the field of creating drugs and vaccines were named, and useful recommendations were given on how to reduce the risks of the disease.
Sergei Netesov, Head of the Laboratory of Biotechnology and Virology at the Faculty of Natural Sciences of NSU, Corresponding Member of the Russian Academy of Sciences, in his report raised all these issues and expressed his opinion on how the situation with coronavirus could develop in the future.
The scientist noted that with the help of tough anti-epidemic measures, observed by the majority of citizens, "covid" in a single country can be defeated, citing as an example China, South Korea, Slovenia and a number of other countries. But not all countries, unfortunately, can organize such a regime - and it will not work to count on it.
Therefore, there are still two scenarios, according to which the situation with the coronavirus may develop. First, we will not be able to eradicate the virus immediately, and it will continue to circulate at least until an effective vaccine is introduced into practice. Second, we will not be able to eradicate it, we will not be able to develop an effective vaccine, and this virus will enter our lives in the same way as swine flu and previous coronaviruses entered it.
Which of these two options the situation will develop will determine the time and efforts made by all countries to combat the coronavirus.
There are currently no vaccines with proven efficacy and protection against infection. The first experimental data may appear no earlier than the end of November this year. Drugs with proven specific action against COVID-19, as stated in the WHO recommendations, have not yet been developed.
The scientist emphasized that in our country there are not enough strict measures to control the wearing of masks, so the situation is not improving. The adoption of such measures would reduce the incidence.
And here it should be emphasized: people who wear masks without covering their nose do not provide themselves and those around them with protection. Sergei Netesov explained that damage to the olfactory nerve located in the nose (loss of smell as a result) proves that infection mainly occurs through the nose. Therefore, people who do not wear masks on their nose are a high-risk group. In the mouth we have enzymes that can prevent the virus from entering the body, so a mask on the lips makes little sense. Earlier we wrote that those who wear glasses are less likely to get infected with "covid".
The effectiveness of conventional masks is about 80%. They do not exclude infection, but they reduce the dose received by 100-1000 times, and this lengthens the incubation period and gives the body more time to develop immunity.
