    Coronavirus Cause 

    • Coronavirus is firstly developed in animals before developing in humans. Actually, it passes firstly from animals to humans,  researchers said that this Virus may have been passed from bats to other animals either snakes or pangolins and then transmitted to humans.
    • This transmission occurred in the open Food market in Wuhan, China.
    • Coronavirus is caused by respiratory droplets by a person who is affected by this virus, touches a surface (with the virus) or then touches anyone's face.
    • One person affects 3 people and 3 more people affected 10 people.
    • It continuously spread by one person to another person.
    • In 2019 it actually related to humans.

    Pathogenesis and immunity

    • Coronavirus infection typically infected the mucosal cells of the respiratory tract. It actually destroyed humans' lungs known as cytokine storm (makes the lining of lungs thicker than normal) which actually refers to the overreaction of the body's immune system.
    • Cytokines are the small protein that is released by different kinds of cells in the body and are signal to the immune system for the site of infection allow immune cells to coordinate their response against the virus. Rarely, the body produces a large number of cytokines during infection. This storm causes a huge burden on the immune system and forces immune cells to the site of infection leads to hyper inflammation which may cause of death of the patient.
    • Coronavirus enters into the lungs and reaches low to respiratory tract where tiny alveoli are present and destroyed them. As alveoli exchanges oxygen and carbon dioxide in our body destroyed healthy cells that make the lungs more vulnerable to bacterial infection so lungs become less functional. Other organs as brain kidney liver become deprived because of oxygen. So the patient needs Ventilators in order to overcome the amount of oxygen.

    Coronavirus Treatment

    • Specifically, there is no treatment present for COVID-19, no cure for this virus its vaccines and treatment are under study. Coronavirus cure is very important because it causes many deaths.
