1. The novel coronavirus that causes COVID-19 is thought to spread mainly from person to person through respiratory droplets produced when an infected person coughs, sneezes or talks. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.

Here's what you need to know:
1.Wash your hands regularly for 20 seconds, with soap and water or alcohol-based hand rub
2.Cover your nose and mouth with a disposable tissue or flexed elbow when you cough or sneeze
3.Avoid close contact (1 meter or 3 feet) with people who are unwell
4.Stay home and self-isolate from others in the household if you feel unwell

2. The population of a place, whether that place is a small town, a big city, or someplace in between can change dramatically over time. The reasons for these changes are many, but they often have one thing in common: an influx of new people moving in.
When the number of people moving into an area is greater than the number moving out, it's called net in-migration. When this happens, there can be both social and economic consequences for the community as a whole. New arrivals may mean more jobs are needed to meet demand, which in turn can cause an increase in real estate values. This can make housing less affordable for longtime residents who might not see their salaries rise at the same rate as living expenses.
In some cases, a high net in-migration can affect local politics and even the relative power of various groups within a community. For example, if more people who vote for one political party are moving into an area than people who vote for another party, the majority party could gain more representation in government or even control of local offices.
