World impacting pandemic of Covid-19 did bring down the world to a grinding halt in early 2020. Though activities slowly started to re-open in 2nd half of the year, the spread is not fully under control. Fear of the second wave continues to loom all over the world.
The spread of this pandemic is mainly attributed to close contact with human beings. Lack of early detection of infected people or people with elevated body temperature, especially pre-symptomatic or asymptomatic is allowing them to freely go about their daily routines. They mix up with other people and are likely to spread the infection.
