The older People get Covid-19 and Younger People

Those with more general underlying health conditions or who are 70 or over may still be more vulnerable to COVID-19 than the general population, so are also advised to stay at home as much as possible, to carefully follow the rules and minimise contact with others.

 More than 50% of all deaths involved people aged 80 years or older. Reports show that 8 out of 10 deaths are occurring in individuals with at least one comorbidity, in particular those with cardiovascular disease, hypertension and diabetes, but also with a range of other chronic underlying conditions.

Then the scientists found the vaccine for Covid-19 and they give it to doctors to vaccinate older people and sometime they will give it to younger people. The time tell in the future. Sometime you all need to know where the virus came from look into the history and you will find the answer.   

SARS-CoV-2 is believed to be a spillover of an animal coronavirus and later evolved the ability of human-to-human transmission. Because the virus is highly contagious, it rapidly spreads and continuously evolves in the human population.
