Impact of Coronavirus in our Body
The first coronavirus case was detected on 31st December 2019 in Wuhan, China. The number of positive coronavirus cases in the world as of now is more than 4,70,000 and the number of deaths is more than 21,000. For most of the affected people, it may be a mild disease, but some people die due to this virus.
The period when the virus establishes itself in a human body is termed as incubation period. The virus attacks the body by getting into the human body cells and then hijacking it. The official name of coronavirus is Sars-CoV-2. This infection gets transmitted when a person inhales the droplets that are exposed to the air when another person sneezes or coughs and also when a person comes in contact with a contaminated surface and hence touch their face, the virus gets transmitted.
The first thing that the virus do to human body is that, it infects the cells that lines the throat, lungs and airways and transforms them into coronavirus factories. These factories then produce a huge number of viruses into the body which ultimately affects the cells.
After the incubation period, most of the people will experience a mild disease. For 8 out of 10 people who gets affected by the virus, their main symptoms include fever and cough. Fever occurs because the immune system is responding to the virus. It releases chemicals called as cytokines to the body as a result. These symptoms can be cured by taking bed rest and it may last for a week.
If the fever sustains it might be due to the immune system overreacting to coronavirus which results into a severe disease. This results in an inflammation in lungs termed as pneumonia and people will need the support of ventilators to help them to breathe in this chronic situation.
The next stage is critical disease wherein 6% of the cases goes to this stage. The immune system starts to fail which causes damage to the body and the chances of death will be high in this stage.
