It is one of the life-threatening diseases caused by Coronavirus. The COVID-19 outbreak has now been renowned as the Public Health Emergency. Every country has become a part of this outbreak.
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.

1 Real-time reverse transcriptase Polymerase Chain reaction i.e. RT-PCR
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.
What is the effect of covid-19 on the World’s economy:
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. The public parks were closed. The markets were shut down. There was a loss of about 2.9% of the gross domestic product (GDP) rate in the previous year.

All the vaccines available worldwide for their inhabitants have gone through trials and have been approved by the WHO and Drug Regulatory Authority of Pakistan (DRAP).
