Corona virus (Covid-19)

Corona virus disease 2019 or covid-19 is an infectious disease of humans caused by a type of virus called corona virus 2 (SARS-Cov-2) causing severe acute respiratory syndrome.

The disease was first identified in December 2019 in Wuhan, China. Later in early 2020, the disease spread worldwide and became a global pandemic.

Common symptoms of the disease include fever, chills and shortness of breath. In some cases, muscle pain, frequent spitting up and sore throat may occur.

In most cases, symptoms are mild, but in some severe cases, pleural effusion (pneumonia) and organ dysfunction can occur.

The average mortality rate of this disease after infection is 3.4%, while the mortality rate is 0.2% in patients under 20 years and about 15% in patients over 80 years. The disease is usually spread through airborne particles produced by the sneezes and coughs of an infected person.

In addition, if the germs of an infected person stick to the surface of various objects in the environment due to sneezing-coughing or touching with infected hands, and if someone touches the surface with the virus and touches the nose-mouth-eyes, the corona virus enters the body through the mucous membrane of the nose-mouth-eyes. remains Symptoms appear within 2-14 days of exposure; Symptoms appear within an average of 5 days.

Diagnosis is usually made by reverse transcription polymerase chain reaction (rRT-PCR) on nasal or throat swabs. In addition to health risks, the disorder can also be diagnosed by the presence and symptoms of lung inflammation (pneumonia) on CT imaging (CT scan) of the chest. It has now become serious in different countries of the world including Bangladesh.
