Interview

How to protect yourself from COVID-19 concentrated enough companies due to the easing of the quarantine after the isolation the newfound “freedom” and feeling contrived security, UNIAN was told by the epidemiologist National expert group for infection control Ekaterina Soyak, co.

How to observe the distinction between safety and sanitary standards in public transport? The handgrips or not?

It is better to avoid contact with surfaces affected by a large number of people. But in transport it can’t be avoided, so we can’t give recommendations not to touch the handrails and fall on each other, it would look silly. Holding the handrail in transport, it is important to monitor yourself and do not touch mucous membranes, do not RUB eyes. Also do not forget to treat the hands, for example, coming out of the subway. At the first opportunity to wash them with soap and water.

Tired of the loneliness quarantined people already collected group of friends and relatives. Do I need to maintain a distance of at such meetings, not to shake hands?

If people do not live together and do not have close contacts in the home, it is desirable to comply with social distance, no hugging and no kissing. Even if they are our close relatives and friends. We do not yet have herd immunity, which would allow to relax.

I note that, according to all forecasts and principles of epidemiology, we will be able to treat this infection with less apprehension, when about sixty percent of herd immunity. We still need to buy it, that is, the majority of the population has to face the virus and recover in the light, or, unfortunately, severe. And someone at all did not notice. In global terms, it would be good, because you develop a herd immunity. Until that happens, the infection will cause a paralysis of society and all our life processes.

I say this not as a challenge, they say, let’s all immediately parabolam. Of course, you need to try not to get sick and not to spread the virus not to infect people at risk of hurt severe. To avoid overload hospitals.

Immunity is protection from infection. I’ve seen publications about that ill COVID -19 may get sick again. How then, can we talk about collective immunity?

There is lifelong immunity to certain infections, and there are short-term. It is believed that this infection is no long-lasting immunity. But, in any case, there is an understanding of herd immunity. This means that in a given period of time people had been ill and still retain immunity to infection (even if it is not lifelong).

Indeed, there was a single publication on cases of re-infection. But also they were denials. And in parallel, was published, in cases of alleged re-infection it was about undertreated cases. That is, people who have fixed the virus again, was goes untreated. Overall, this is not those cases which can be taken as the standard.

Do I need to adhere to health recommendations (mask, dist, antiseptic) to a person who is in the form of light had coronavirus?

Should follow, because the question of duration of immunity after the disease is not yet known. It is believed that this virus is able to mutate. This can be compared to flu, which we do not have lifelong immunity, and every year can get sick again, or another strain. In any case, I would not say that you can completely relax. Although a certain period of time the immune system in humans, of course, will. But we are talking about intervals in a month or two.

Do I have to try to avoid the crowds in the fresh air?

The crowd in the air, of course, better crowds indoors. And although up-close person can transmit the infection (coughing or sneezing etc.), according to all principles of infection control epidemiology is considered that these risks are minimal. There is the sun, the air drafts, so the infection dissipates quickly. About the crowds on the street, I wouldn’t worry, not throwing in a lot of effort and attention.

Most do not wear masks, as expected. See on the streets – one on chin, one nose opened. When you can afford such a relaxation, and when you need to adhere to the norm?

If the Ministry and the people who make the administrative decisions in this area, leave mask mode, so they are somewhat guided. Taking as a basis statistics, forecasts. If mask mode is needed, that is not an option to wear masks properly. In fact, we were talking about a misuse of the remedy.

Having a testimony of wearing masks, it must be fully and efficiently, covering the nose and mouth, time to replace, if possible. Again, not to leave the mask on the surfaces, put it in his pocket. In fact, when we remove the mask, the pathogens that might be on it will remain on the surface, on hands, on clothes.

Now everywhere conduct temperature screening. Does this make sense, because the temperature in humans can rise even just from excitement?

A particular meaning is, why he is called screening. It is a way to somehow weed out people according to markers that may indicate an infectious disease. Still, the healthy increase in temperature is not observed around the clock.

Once again to measure the temperature – it’s good practice, if it is done efficiently. For example, do not measure it in the scorching sun when all is hot, and the data may be unreliable. But temperature screening at the entrance to the room, as is done now, is normal. I would leave the practice.

Naturally, it is desirable that after the detection of elevated temperature was carried out and other activities. If a person has a temperature of 37.5 – 37.8 C, and preferably not just wrap him up and not let into the building. This is not correct and will not be meaningful. It is better to offer aid, call a doctor or ambulance. To potentially the patient did not go just to transport home.

I read that people can be carriers of the virus without having symptoms.

Yes, people without clinical manifestations of the virus can spread. Also they can spread during the incubation period. That is why COVID-19 complex for anti-epidemic measures – because there are people who have difficult to identify. You can’t fight it. Everyone can be a potential carrier, why we wear masks. To our pathogens don’t spread to others.

In “Ukrzaliznytsia” said that in passenger cars, following in the regions where they have not weakened the quarantine in one compartment will not be more than two people. What do you think about this, it makes sense?

The decision reduces the number of contact persons with potential patients. It’s simple math. If four people in a cabin sick, have three contact person. If of two people one is sick, contact only one. But measures to reduce contact are meaningful and help to reduce the incidence only in combination with other measures (personal hygiene, masks, etc.).

Promise to conduct intensified disinfection and measure the temperature.

Really, everything you can think of – temperature screening and less people in the compartment. Of course, a single division would have been perfect. But it is generally not economically feasible.

What about masks, whether they are in the compartment?

The logical mask to wear in places where we are short and can’t abide by social distance. While in the compartment of a passenger car is a long – term contact, consider, home. There does not have to be masked, because we go together and will still breathe the same air.

Another question about how to safely travel. Especially if you need to carefully evaluate disinfection in rented accommodation?

Hygienic cleaning is important anytime, not only during a pandemic COVID-19. After using contacts is transmitted to a large range of other infections, which you should not forget. Any special criteria about the safety of housing in travel not allocated. After all, clean accommodation, and so for all easier and more enjoyable.

Plus, on the surfaces of the virus survives, not so long. Better get used to personal hygiene activities. Not matter how worn out the surface, if we touched them, and then licked his fingers or rubbed his face. It is impossible to figure out what and how processed. But for a monitor it is possible.

I guess not for the mountain opening concert halls. How to be in a closed room, designed for a thousand people or more to sit a few hours in the mask, or rather the temperature screening?

Honestly, like any infectious disease, it’s difficult to answer this question. I think if there is still a real threat of infection, if we have not crossed the threshold, it is better not to speak yet about the mass concerts in large halls etc. If we talk about them, it is not necessary to suck the thumb of sanitary measures. Yes, temperature screening can be conducted. But, for example, be in concert in the mask – it would be completely strange, unpleasant for anyone sight. In this case, it is better to move.

How to organize something more secure at the office? Enough to put antiseptics in bathrooms?

A lot depends on the office and operations of the company. The question is best considered individually but there are General rules. For example, to organize continuous mode of ventilation. To organize the employees who will be responsible for the quality of cleaning of the contact surfaces (handles, doors, switches, buttons drain the toilet). They should be regularly wiped with antiseptic. Also important mask mode for visitors. That is, if people are working in the same room in the office, no need to scoff at them, demanding from morning till night to sit in the mask. But if the visitor comes from outside, it needs to be masked. At the same time can mask the office staff.

Many say that fall will be the second wave of the disease. Epidemiologists are preparing for this once, the conversations are?

Professional conversations are, but no more. Special training we have. Rather, it is necessary to prepare a medical institution, so they can take a large number of cases. Today we see that all countries responded differently to the pandemic. They all had different situations with flash. So we still need a comprehensive approach to the analysis of the situation, to understand what to expect in the fall.

Yes, we do hear about the second wave, but to ensure it I can’t. I don’t have at the disposal of the other figures, except those which are known to all from the Ministry. But in the fall added seasonal SARS, which will aggravate the situation from COVID-19. That is, the coronavirus may remain at the same level, but added other infections, which will cause a more severe course.

I read that people who were vaccinated against the flu, thanks to stronger immunity, was apparently not infected with the coronavirus. Have you ever noticed that?

I study not seen. It was a study on the impact of the tuberculosis vaccine (BCG) for over COVID-19. But, in my opinion, yet the final conclusions. The statement that the flu vaccine somehow helps from COVID-19, are incorrect. Just when we vaccinated against the flu, we are not facing a double infection – COVID+flu – what the body would be much clonees to cope. But you can’t count on the flu shot clearly profilaktirujut coronavirus. The flu vaccine includes influenza strains that are unable to prevent COVID-19.
