Doctor-therapist of the highest category, toxicologist, member of the Science Journalists Club Alexey Vodovozov in an interview with Sputnik radio described what to do in case of contact with an infected coronavirus.
The specialist revealed that the risk of contracting coronavirus depends on the proximity of the contact: close communication without protective equipment or contact with a COVID-19 patient at a distance in the presence of a mask. Thus, the tighter the contact, the higher the likelihood of transmission of the infectious dose.
At the same time, such a probability, the medic continued, is far from one hundred percent.
The specialist advised that in case of contact with a sick person, no special measures need to be taken, that is, “you do not need to run to do PCR.” “If the person with whom you contacted is officially ill and is registered with Rospotrebnadzor, accordingly, his contacts can also be contacted,” Vodovozov recalled. At the same time, he recalled that the coronavirus is not as infected as, for example, measles.
Vodovozov recalled that now the main prevailing variant of the coronavirus is the delta strain, which has a shorter incubation period. Therefore, in case of infection with COVID-19, the symptoms will appear rather quickly – from 2.5 to 5 days. In case of contact with an infected person, you must carefully monitor your well-being.
The doctor concluded that when symptoms appear, a doctor should be called, who, among other things, should be informed about contact with a carrier of coronavirus infection.
Rospotrebnadzor previously reported that it is impossible to find out exactly which strain of coronavirus a person is infected by external signs. This can only be found out in laboratory conditions.
The COVID-19 strain can only be determined by sequencing – decoding the genome of the virus or its fragment (S-protein gene) in the laboratory. In this way, the presence of key mutations can be detected and then the strain itself can be identified.
The representative of the World Health Organization (WHO) in Russia, Melita Vuinovich, believes that the only way to protect against mutations of the coronavirus is vaccination. According to her, the more often the virus is transmitted, the more opportunities for its mutations, and vaccination reduces transmission.
The representative of the organization noted that WHO is tracking emerging variants of the virus, and some of them are of concern. We are talking primarily about the strains “alpha”, “beta”, “gamma” and “delta”. The most interesting option right now is the lambda, although it has not yet supplanted the delta option.
Infected with coronavirus in the world as of 24 August
As of August 24, since the beginning of the pandemic, more than 213.3 million people have been infected with the coronavirus in the world, more than 4.4 million have died, and 190.8 million have fully recovered.
