The source of COVID-19 is an infected person or an asymptomatic virus carrier. As with other viral infections, there are different ways of COVID spreading. Experts distinguish two basic modes of transmission of COVID-19 infection – airborne droplets and by close contact.
First symptoms
First symptoms can be observed in 14 days after contact with someone with COVID-19 infection.
The main symptoms of the coronavirus are the following:
- weakness;
- high temperature;
- dry cough;
- sore throat;
- headache;
- confused breathing;
- loss of smell and taste.
Sometimes there are also rare symptoms like:
- nausea;
- diarrhea;
- bluish skin;
- chest congestion;
- hemoptysis.
How is COVID-19 transmitted?
The main routes of transmission of COVID-19 are by airborne droplets and by contact with an infected person.
- by airborne dropletsThis is the most common way the virus is transmitted. Virus parts get into the air when someone coughs or sneezes. Further droplets of sputum with viruses enter the respiratory tract or the mucous membrane of the eyes of a healthy person. This method of infection is possible with close contact within 1-2 meters.
- by contactInfection with the COVID-19 virus can also be transmitted through objects that the infected person has touched or used for a long time. These can be personal belongings of an infected person, handrails in public transport, money, and other surfaces.
Sputum with virus particles settles on these objects. The virus remains vital for up to 72 hours. A healthy person takes an object, and then touches his face with dirty hands, bringing a virus into the body.
Infection is also possible through close contact with the infected one – through hugs, handshakes, or kisses. This transmission route COVID-19 is much faster.
Besides, there is also a dust-air transmission method. This COVID-19 transmission mechanism is very similar to airborne droplets. However, in this case, the virus settles on small dust particles. Virus particles are smaller in droplet size, stay in the air for longer, and are carried further. As a matter of fact you can get infected even at a distance of 4 meters.
What to do if I have a coronavirus?
If you have mild symptoms of coronavirus, then go to isolation mode and observe your condition. Very often, the coronavirus is confused with the flu or the common cold, and sometimes there is no need for urgent help.
If your fears are confirmed and the condition worsens – immediately seek medical help or call 911. Do not self-medicate without consulting a doctor. It can only harm your health.
Knowing the ways of COVID-19 transmission, take precautions in public places, and limit contact with other people. Take care of yourself and your health.
