Five tips to 'living with the virus'

Five tips to 'living with the virus'

The unlock 1.0 is put into action but, with Covid-19 vaccine still months away, Prof. K Vijay Raghavan, Principal Scientific Advisor to the Government of India, has given five tips to ‘living with the virus’.

Speaking to India Science Wire, Raghavan said that this is the beginning of a new normal and suggested that we must learn to live with the virus.

"Either we must change the virus, or we must change ourselves; changing the virus is going to take time," he said while listing five tips on how we can change ourselves to face the pandemic:

<strong>1. Wear a mask when you step out of the houses</strong>

Recent studies have found that when a person speaks, about 1000 tiny droplets of saliva comes out. If that person happens to be infected with novel coronavirus, then each of these droplets will carry thousands of germs. Large droplets will fall off the ground, usually within one-metre distance. However, the plum of tiny droplets can float in the air for a longer time, mainly if the area is not well ventilated. Many people who are infected by the virus do not show any symptoms. Therefore, they may not even be aware that they are affected. Wearing a mask protects not only us but others as well, if we are infected. We have prepared a handbook on manufacturing homemade mask, which one can use to make their own face cover.

<strong>2. Practise vigilant hand hygiene</strong>

An analysis of 75,465 Covid-19 cases in China by a WHO-led study shows that novel coronavirus is primarily transmitted between people through respiratory droplets and contact routes. Thus, the Covid-19 virus can be transmitted when one comes into direct contact with infected people. Or when we touch surfaces in the immediate environment or objects used by the infected person (e.g., door handle and washroom tap). Our normal urge is to reach our face. When we wash our hands thoroughly with soap for at least thirty seconds, the virus, if any, on our hands is destroyed. There are suggestions that the virus may also be transmitted by faecal and oral routes. Hence it is better to wash the hands and legs.

<strong>3. Maintain social distance</strong>

Most likely, the infection happens through direct contact or inhaling the droplets shed by an infected person. Droplets in usual conditions travel about a metre from the infected person. Keeping a distance of one metre from one another in markets, offices, and public transport would greatly help. Young people can get infected without showing symptoms, and they can infect the elderly. Hence, we need to take special care to maintain physical distancing, particularly with the vulnerable like elderly, those who are ill in multiple ways.

<strong>4. Test and tracking</strong>

If someone turns out to be Covid-19 positive, then one has to go back in time and identify proximal contacts of that person and identify them. We must test them. Only an infected person can transmit the virus to others or contaminate a surface and spread the virus. If most of the infected persons are identified, then controlling the transmission of the virus becomes easy.

<strong>5. Isolation</strong>

The people who have been identified as positive cases should be isolated. Once isolated, the infected person can receive proper medical attention. Further, as they remain isolated, an infected person cannot spread the virus to others. The tentacles of the infection can be cut.

"If one can do this with high speed the last one and follow all the others, then we can have a semblance of a normal life while we wait to do something for drugs and vaccine. If we don’t do any of these things and if we slip up on any one of these, then we will have a problem," said Raghavan..
