Contact Tracing has emerged a critical method to control the spread of Covid-19. Apart from finding people suffering from Covid-19 infection, the method of Contact Tracing also helps to track those who have come in contact with the infected person. The application, developed by the Ministry of Electronics and Information Technology, Government of India has proved to an ideal tool for Contact Tracing.

Earlier, some people who people who had come from abroad were trying to hide their history of international travel. These people were also reluctant to declare the identities of others who had come in their contact. The Ministry of Health and Family Welfare had to gather information of individuals who had taken international travel from various ministries including the Ministry of Home Affairs, Ministry of External Affairs and Immigration Centres of all citizens. Then, the Ministry of Health contacted these people through different means.

Even at the community level, when one individual was found Coronavirus positive, the authorities immediately started looking for all persons who could have come in contact of the patient. Considering this fact, the National Centre for Disease Control established a surveillance and response system.

What is Contact Tracing?

Contact Tracing is the monitoring process of people coming into contact with an infected person. The Coronavirus can easily spread from one person to another through direct or indirect contact. However, people who come into close contact with an infected person are at greater risk of getting infected. Therefore, all those who come in contact with a Covid-19 patient are kept under quarantine for 14 days. It is important to keep these individuals under observation, so that they can be taken care of and can be given immediate treatment if required.

There are three stages of contact tracing:

  1. Contact Identification

When a person is confirmed to be COVID positive, authorities identify and trace individuals who would have come in his/her contact since the onset of the disease by inquiring about his/her activities.

  1. Contact List

All persons who come in contact with the Corona virus infected person are listed. They are asked to isolate themselves and contact the medical team if symptoms are visible. These people who came in contact with the infected person are also given information about disease prevention.

  1. Follow-up with Persons who came in Contact with the patient

Health officials remain in regular contact with all persons had come in contact with the infected individual. They monitor their health condition and check for symptoms of the virus. Contact tracing is essential to prevent the spread of corona virus.

So, what individuals can do, is to adopt one simple habit that- while, we follow lockdown and stay home safe, on occasions whenever we meet or interact any persons in a day, one can simply note down on paper/ diary, their names or reference which will help in event of need for contact tracing.
