Perhaps we should rather ask ‘what ARE coronaviruses’ because they are a group of sub-microscopic infectious agents causing disease. Those illnesses include mild-to-severe respiratory tract infections in humans. Minor conditions include common colds (although these have other causes). Known serious infections include SARS, MERS, and COVID-19 causing the current pandemic.
Why is the COVID-19 Pandemic Such a Problem?
COVID-19 is caused by a new coronavirus, called SARS-CoV-2 that surfaced in Wuhan, China in late 2019. Humans, mammals and birds can infect with it, although it only makes humans ill. If we catch COVID-19 it attacks our breathing system, which is how we can spread the virus by laughing, shouting, coughing or even exhaling.
Mucus floods our lungs if we become seriously ill. We can’t breathe properly, our blood lacks life-giving oxygen, our organs suffer damage, and we can die. Hence it’s important to know what the warning signs of this coronavirus are.
The symptoms are coughs, fever, or chills, shortness of breath, or difficulty breathing. We may also have muscle or body aches, sore throats, new loss of taste or smell, diarrhea, headaches, new fatigue, nausea or vomiting, and congestion or runny nose. However, it’s unlikely we will show all of those signs at one time.
What Was the Coronavirus Origin Causing COVID?
We don’t know where the SARS-CoV-2 virus that spread from China came from. However, we do know it thrives in moisture in our breathing system. And we can spread it the through the air in tiny droplets when we breathe out forcefully or sneeze. That in a nut shell is what the COVID-19 coronavirus is, and how we can share it.
If somebody else breathes our droplets in, then they become a new host where it can multiply, attack their bodies and even kill them. The only way to stop this is to prevent human-to-human transmission. The virus is flourishing because human are stubbornly independent, and we like to do things our own way.
