Later it spread worldwide affecting several lives as well as the world’s economy. The World Health Organization, WHO regarded this disease as COVID-19 on 11th February 2020.

Which Organs are mostly affected?

How does the disease spread?

The disease can spread if the individual touches the virally contaminated object or surface. It can also spread through direct contact with the affected patient’s respiratory droplets. The virus can survive on nonliving surfaces for a while. The disease can also spread through the air. The infected individuals can transmit the disease to the people they are having physical interaction with.

How the virus affects the body?

It affects the body by entering and residing inside the human body. The primarily affects the lungs causing respiratory disease. It attaches its surface proteins with the receptors of the body cells and invades inside. They have specific receptors ACE2 that helps in attaching with the human cells.

It then resides inside the healthy body cells, replicates, makes its copies, and spreads from one organ to another.
Mostly 75% of the covid cases are mild ceasing after fever and cough but if no care is taken then it might get severe resulting in the death of the affected individual.

2 Rapid antigen test
3 CT scan
4 Past infection can also be detected through serological reactions.
5 Nucleic acid test can also be done which helps in detecting the viral mRNA genome.

The world’s economy has been affected badly due to the pandemic. In February, the lockdown was imposed in the majority of the countries. This had a worse effect on their economy.
