The virus emerged in December last year, but now the whole world is dealing with this pandemic called COVID-19.

Incubation period

Coronavirus works by getting inside the cells of your body and hijacking the cells. It is officially called Sars-Cov-2 that invades body when the person breathes it in or touches a contaminated surface. Firstly, it infects the cells lining your throat, lungs and airways then turns them into Coronavirus Factories that replicate huge numbers of new viruses that can infect more cells.

At the early stage, people normally do not get sick and this period is of five days on average.

Mild disease

This stage almost all people experience, as eight of ten people have common symptoms like fever and cough; moreover, body aches, headache and sore throat are possible, but not guaranteed. The virus as a hostile invader and signals to the rest of the body infects body by releasing chemicals called Cytokines.

Firstly, the immune system fights against the virus but the disease progresses, it will be due to the immune system overreacting to the virus. Initially, it leads to body inflammation; much inflammation can cause collateral damage throughout the body. At this stage, people face difficulty in breathing so they may a need of a ventilator, and near about 14 per cent are affected by this, based on the data from China.

Critical disease

Nearly 6% people become critically ill. At this point the body is starting to fail and there is a real chance of death because the immune system is now spiraling out of control and causing damage throughout the body that can lead to septic shock in which blood pressure drops low levels and organs stop working and fail completely.

Acute respiratory distress syndrome caused by widespread inflammation in the lungs stops the body receiving oxygen it needs to survive, which can stop the kidneys from cleaning the blood and damage the lining of your intestines.

Treatment by this stage will be highly invasive and can include ECMO or extra-corporeal membrane oxygenation by implanting an artificial lung that takes blood out of the body through thick tubes, but eventually, the damage can reach to fatal levels at which organs can no longer keep the body alive.
