COVID-19, a severe respiratory disease mediated by SARS-CoV-2 virus, is an extremely infectious. This virus was a recant outbreak from Wuhan City of China in late December 2019, but no remedy has been found yet. The coronavirus can spread mainly from person to person when they come in close contact with each other. Respiratory droplets from an infected person’s infect any nearby people. Furthermore, asymptomatic person can also infect others. Data and information were searched from Web Science, Google Scholar, and PubMed databases, and the articles published before June 2020, using relevant keywords. WHO, CDC and other Govt. Agencies have published a protective measure for better prevention of the COVID-19 disease until vaccines or any other antivirals become available. “Stay at home”, “Uses of Mask”, and “Wash hands frequently for 20 sec” are some of the general strategy for precaution. However, it is not possible for the ‘must travellers’ and/or “front-line workers” to “stay at home”. The concerns of the must-travellers and front-line workers to avoid any unwanted consequences that may arise from their travelling issues were discussed in this review.
