Coronavirus disease 2019 (COVID-19)

- It is a contagious (infectious) disease caused by severe acute respiratory syndrome coronavirus 2. The disease was first identified in December 2019 in Wuhan, the capital of China's Hubei province, and has since spread globally, leading to the continuing coronavirus pandemic.

Common symptoms

Include fever, cough, and shortness of breath. Other symptoms may include fatigue, muscle pain, diarrhea, inflammatory disease, loss of smell and abdominal pain.

The time from exposure to onset of symptoms is usually around five days but may range from two to 14 days. While the bulk of cases end in mild symptoms, some reach pneumonia and multi-organ failure.

On 9 April 2020, over 1.49 million cases are reported in additional than 200 countries and territories, leading to over 89,700 deaths. over 337,000 people have recovered.

Transmission

The virus is especially spread during close contact and by small droplets produced when those infected coughs, sneeze or talk. These droplets might also be produced during breathing; however, they rapidly fall to the bottom or surfaces and don't seem to be generally spread through the air over large distances.

People might also become infected by touching a contaminated surface so their faces. The virus can survive on surfaces for up to 72 hours. Coronavirus is most contagious during the primary three days after onset of symptoms, although spread could also be possible before symptoms appear and in later stages of the disease.

Diagnosis

The quality method of diagnosis is by real-time reverse transcription-polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. The infection can even be diagnosed from a mixture of symptoms, risk factors and a chest CT scan showing features of pneumonia.

Recommended measures

Recommended measures to forestall infection include frequent hand washing, social distancing (maintaining physical distance from others, especially from those with symptoms), covering coughs and sneezes with a tissue or inner elbow and keeping unwashed hands aloof from the face.
