World Health Organisation appreciated India’s efforts in containing the pandemic. It also lauded the Indian government’s political leadership that focused on developing diagnostics and scale it up, NDTV reported. However, the world nodal health agency also asked the country to focus on data management of the pandemic.

According to WHO, the main challenge for India is its demographics, heterogeneity and the fact that India has multiple epidemics going on every state.

In an exclusive interview with ANI, Dr Soumya Swaminathan, Chief Scientist at WHO, said: “The Government of India took extremely serious steps from the beginning and put in place certain measures in January itself based on the WHO recommendations. Today, India is doing more than 200 thousand tests a day. Now, India is developing testing kits. It is a big achievement for India that in the last couple of months as India has become self-sufficient in testing kits and being able to scale up.”

“However, I would like to say that there should be a focus on data. By that, I mean that we need to have a systematic approach to looking at the data,” added Dr Swaminathan. She said that the moment people start focusing on the total number of cases and the total number of deaths — it gives only part of the story.

“There needs to be some kind of national guidelines on how you report data. Otherwise, you cannot compare. Everybody is reporting things in different ways,” she said.

She informed that the most important point is to know the epidemiology of the disease, i.e., where and what is the number of cases per million population and it all depends upon the tests. “If we do not test, we are not going to find the case. Reporting of the case alone is not sufficient. We need to know how many tests have been done. Most importantly, we need to know the test positivity rate. This should be under 5 per cent. We also need to know the percentage of positivity of disease surveillance. SARI and ILI surveillance should be under 5 per cent. Then, we need to keep track of the doubling time,” Dr Swaminathan noted.

“So, instead of focusing only on numbers, all we need to know things like — how the epidemiology is going. Is it going up or down or it is on a plateau. That is what we need to know,” said the Chief Scientist of the WHO.

Importance of contract tracing

Dr Swaminathan underlined that it is very important to know how many contacts are traced for every case and how many potential carriers are quarantined and within what period of time.

She elaborated on contract tracing and said: “If you can do it within 48 to 72 hours, then only it is helpful. There is no point tracing contact after 10 days. It is too late. As soon as cases are detected, we have to trace the contact and the higher the number of contacts you trace, the higher number you can put in quarantine is better. This shows how well our public health system is doing.”

According to the doctor, there is another set of criteria in the clinical care and that is to know what is the bed capacity for mild/severe cases, what is the ICU occupancy and the mortality rate.

“The death has to be calculated properly because deaths follow after two or three weeks of the occupancy. You take as a numerator the number of deaths and denominators should be the number of cases you have two weeks ago, not today. That actually reflects your mortality rate/case fatality rate,” she said.

Epidemiological parameters to detect the prevalence of antibodies in the community are essential to know the trend. “Like the ICMR did serosurvey– something you need to do periodically to see how much of the population has been exposed,” Dr Swaminathan said.

She added, “We need to have a dashboard of criteria which every state should have and it helps every state to monitor how they are doing. This also helps to compare data across the states and the government can give more resources to those states which need more strengthening, like in terms of bed shortage, ICU.”

“So, there is a need to develop this kind of mechanism because Covid-19 is going to stay for a long term as it is not going to over in few months,” she mentioned.

Swaminathan also highlighted the importance of addressing other diseases as well and the healthcare system should also cater to those diseases.

“We cannot just focus on Covid-19 alone because we have other health problems in the country. Otherwise, those health problems such as TB, vaccine-preventable diseases like measles, institutional deliveries, elective surgeries, and rehabilitation may get worse than Covid-19. So those things have to be brought back to normal and capacity of the healthcare system has to be increased,” she said.
