Coronaviruses are a large family of viruses that constantly circulate in nature and mutate. They consist of one RNA molecule (ribonucleic acid, a macromolecule that is part of all living organisms, capable of self-healing). The airways are affected. Due to the high mutation, it is very difficult to develop a vaccine.
Alpha – coronaviruses – are present in the structure of ARVI for the whole year, cause mild diseases.
Beta – coronaviruses – are the causative agents of SARS. This also includes the new coronavirus COVID – 19, first appeared in the Chinese province of Hubei, spread very quickly around the globe and infected entire countries. In March 2020 declared a pandemic.
The severity of the disease manifests itself depending on the level of immunity of each person.
A person could be contact and not know this, transfer the disease in a mild form, and think that it was ARVI, get pneumonia, and that was coronavirus. In this case, the ELISA method shows the presence of immunity against coronavirus infection after 14-20 days (Ig G antibodies).
Since the virus is transmitted by airborne droplets and by contact – the detection of the virus itself in the respiratory tract – is the most reliable diagnostic method. This allows you to do PCR (polymerase chain reaction) smears from the nose and throat. But after the illness, the PCR technique does not necessarily indicate the presence of a live virus, although it finds it.
In this case, only ELISA confirms that the disease is transferred and immunity has formed.
A very important condition for the correct diagnosis of coronavirus infection is the collection of material for research, storage and transportation.
The presence in our medical center “Valeo” of our own accredited laboratory equipped with modern equipment, including Real-time PCR, allows us to completely eliminate the stage of transportation, which ensures an improved quality of analysis.
Our immunity is our health, protects us from all sorts of viruses and coronaviruses. A person will become ill after immunity after contact with the virus – or not, how the disease will proceed and how soon recovery will come.
Strengthen your immunity: lead a healthy lifestyle, eat right, exercise in the fresh air and be tested in a timely manner for coronavirus infection.
Be healthy ! Take care of yourself!
