Ways of Transmission of SARS
In order to determine the methods of prevention of SARS, it is necessary to begin to understand: how exactly is the infection of this infection? It seems that everything is obvious, but there is an unfounded opinion that it is possible to get sick from draughts or wet feet. At the same time, some of the ways of infection that really exist, few people know, so it is worth to understand this issue.
Everyone knows about the possibility of infection of SARS from the patient of this infection. In fact, patients with SARS are most contagious since the incubation period and during the first two or four days of the disease (i.e. 2-4 days from the moment the first symptoms appear). Then the patient's body begins to fight the virus, as a result of which, viral particles become less, and infect them with someone-more difficult.
The body deduces viral particles with droplets liquid through exhaled air, cough, sneezing. For example, during the sneezing in the environment hundreds of thousands of microorganisms fly at a speed of 160 km/h, and their flight range is 2-5 meters. Therefore, for a long time the airborne path was considered the most common (some of them now believe). In this way, influenza virus and coronavirus are usually transmitted.
However, as we already know from the article "What is SARS?", the most common viruses that cause SARS are rhino, which are not usually transmitted through contact with infected droplets fluids. Through saliva (such as kissing) they are also usually not propagated. The entrance gate of the rinovirusnoj infection are the mucous membranes of the nose and the Konjuktiva eyes, and therefore, conversations or even kisses are less important than a handshake. It is worth the patient to wipe the nozzles (actually, in the nose rhino and prefer to cause inflammation), and then, do not washing their hands, shake the hand of another person-the virus is already transmitted. It remains only to scratch your nose or to rub your eyes. Thus, the second way of infection of SARS (it is now most experts call the most common)-the contact path.
A settled virus can infect another person at least two hours. Just imagine how much you can touch in these two hours! And how much you can sneeze, if not cover your mouth in the process! Here we move to the second part of the contact path of infection-through personal belongings of the patient and other items. The fact that the handkerchiefs with the nozzles of the patient should not be scattered throughout the apartment, and the dishes used by them should be thoroughly sanitized-this, perhaps, most known and understandable. But do not forget that some viruses that cause SARS can live on the surface of objects (eg, door handles, Kranikah in the bathroom, clothes, toys, etc.) for a few days. For example, on tissues and paper viruses can remain active for 8-12 hours, on plastic and metal surfaces – up to two days, and on glass – up to 10 days.
The ways of transmission described above are the most common and more or less known. However, there are other ways. For example, the water path of infection, which is typical of a small number of viruses. Mostly for adenovirus. Thus, mass water procedures (water parks, swimming pools, etc.) are an additional risk factor. Especially if the water in which bathing takes place is poorly treated.
There is also a fecal-oral way to transfer some viruses. For example, enteroviruses, Reovirusy. Moreover, Reovirusy can also be transferred from animals. Therefore, do not forget to wash your hands after visiting the toilet and changing the diaper, disinfect the door handles and unscrew in the bathroom, etc.
As for wet legs, draughts and other cooling procedures – contrary to ethos opinion, they have no direct relation to SARS. Ari is so named-viral. Accordingly, it is not possible to get infected without contact with the virus. Cooling can only temporarily reduce the local immunity in non-hardened (not accustomed to cold and temperature changes) person. If at this point the body encounters a virus-the probability that the virus will survive, only slightly increases, but it is likely that and without cooling the infection would have occurred.
Thus, it is possible to infect the SARS in the following ways:
- Airborne droplets (mainly influenza virus and coronavirus);
- Contact: Through the hands of the patient, or rather, the way of the nose-hand-arm-nose/eye (typical for rhinovirus); Through personal belongings of the patient and other objects to which the patient touches with dirty hands (after their mouth is covered during coughing/sneezing or rubbing nozzles) or on which there are viral particles with dropletsed liquid, excreted by the patient during coughing/ Sneezing;
- Water (adenoviruses);
- Fecal-Oral (enteroviruses, reovirusy).
Based on the above, some conclusions can be drawn about the methods of prevention. For ill: it is necessary to cover mouth during coughing and sneezing; For all: it is necessary to observe the rules of personal hygiene (in particular to wash hands, especially after games with animals and to visit a toilet), and also not to visit pools, water parks and other places of a mass bathing in the period of epidemics adenovirus infection.
