Here is one answer to me that I received 2 days ago:

Aunty, it’s typical of all coronaviruses (the main viruses that cause colds) and flu viruses to continually mutate. As they mutate, the illnesses they cause become less severe. This usually means they become more contagious – mainly because people are less sick and are more likely to be active and mingle among other people.

All the evidence suggests this is true of Delta variant. Although it’s more contagious, the illness it causes is much milder. A year’s worth of data shows the the Wuhan virus itself tends to cause very mild illness in people under 65 without underlying health conditions. It also shows that people over 65 or those with underlying health conditions can be successfully treated as outpatients with early treatments. The mainstream media is trying very hard to conceal these facts because the goal is to scare the wits out of people to get them to take these dangerous experimental vaccines..
