What Is Coronavirus (COVID-19)?
A coronavirus is a kind of common virus that causes an infection in your nose, sinuses, or upper throat.They’re
called coronaviruses because under a microscope,
they look like a crown. Most coronaviruses aren’t dangerous. But in early 2020, after a December 2019 outbreak in China, the World Health Organization identified a new type of coronavirus.
But in early 2020, after a December 2019 outbreak in
China, the World Health Organization identified a new
type of coronavirus. Officials named this new virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
This is the virus that causes COVID-19.
What is COVID-19?
Coronavirus disease 2019, or COVID-19, is a disease
that can cause what doctors call a respiratory tract
infection. It can affect your upper respiratory tract
(sinuses, nose, and throat) or lower respiratory tract
(windpipe and lungs).The COVID-19 outbreak quickly
spread around the world. It spreads the same way other coronaviruses do, mainly through person-to-person
contact. Infections range from mild to serious.
COVID-19 is one of seven types of coronavirus, including the ones that cause severe diseases like Middle East respiratory syndrome (MERS) and sudden acute respiratory syndrome (SARS). The other coronaviruses cause most of the colds that affect us during the year but aren’t a serious threat for otherwise healthy people.
What are early symptoms of coronavirus?
Early symptoms include:
- Fever (high body temperature and very fast heart beat)
- Dry Cough
- Fatigue (tiredness)
The virus can lead to pneumonia, respiratory failure, septic shock, and death. If you notice these severe symptoms in yourself or a loved one, get medical attention right away:
- Trouble breathing or shortness of breath
- Ongoing chest pain or pressure
- New confusion
- Can’t wake up
- Bluish lips or face
If you’re exposed and infected, symptoms can
show up in as few as 2 days or as many as 14.
