SARS-CoV-2 is a new type of coronavirus, which began to spread in December 2019 from Wu-han, China. It causes an infectious disease called COVID-19. The virus is able to propagate from human to human a spreads through air droplets during coughing, sneezing or body contact.
The new type of virus spreads quickly. According to preliminary data, one patient causes an infection of other 2-3 people on average. The disease is unfortunately connected to high mortality rate. Some studies suggest the mortality rate is between 2 and 7% of patients.
The disease can be symptomless or just like a common cold. However, it can also be severe or even fatal. The most common signs of infection are fever (88%), dry cough (68%), shortness of breath (18%), fatigue, sore throat, migraine and muscle aches (14%). Less common symptoms are chills (11%), nausea and vomitus (5%) or diarrhea (4%). Rhinitis is an unusual sign.
According to the available data, the incubation period takes approximately 2 weeks.
The most accurate method is using PCR (polymerase chain reaction), which is able to detect the genetic information of virus in the sample. It is therefore independent on the immune reaction of your body and can reveal the virus as soon as possible with maximal sensitivity and specificity.
Slightly less pleasant but the more secure method of collection is through the nose: the wire is bent by the tube to an angle of 120° (be careful not to touch the wire with anything other than the inside of the tube), insert deep into the nose (at least 4 cm), using slight pressure wipe the back wall of the nasopharynx.
The second option is through the mouth: the wire is bent by the tube to 90 degrees, lead it through the mouth beyond the tonsils, wiping the back wall of the nasopharynx (directly opposite you behind the tonsils), so that the entire brush touched just rear walls. When taking the sample, it is important to avoid the tongue and other mucous membranes on the sides.
The fastest way is to use some kind of rapid antibodies test. These tests are cheaper and you can use them at home. They are slightly less sensitive and specific, but still very important for screening of the disease. Rapid antibodies tests do not examine the presence of virus in your body. They simple show whether your body has been infected by the virus by checking present antibodies.
There are two types of basic antibodies that your immune system produces - IgG and IgM. Right after the infection, your body begins to produce IgM, after a couple more days, production of IgG starts. Having a high level of IgM and no IgG means your body is currently fighting acute coronavirus infection. Having a high level of IgG shows that your body has already fought with the infection for a longer period of time.
In every case respect the recommendations stated by our government. I case of a carantine, do not go outside when not necessary. Use a respirator and/or face mask to protect yourself and others. Wash your hands frequently. Avoid unnecessary contact with others.
Surgical mask is a barrier to splashes, droplets and spit. Mask protects your surrounding for situations when you are contagious (even unknowingly). Respirators protect from the exposure to airborne particles (including bacteria or viruses). They are designed to seal tight to the face and stop the particles from outside world. Respirators are made mostly for your own protection.
Simply, an FFP3 will offer greater protection than FFP2 and FFP1. The classification depends on the number of particles that are able to go through the respirator. The American CDC recommends the use of at least FFP2 respirators to prevent the inhalation of infectious particles. They can ensure that 95% of particles of 0.3 μm will not pass through. FFP3 respirators stop at least 99% of them.
