Director General of the Indian Council of Medical Research (ICMR) Dr Rajiv Behl assured that there is 'no cause for worry' as there has been rise in covid patients in hospitals across India and other countries, he also mentioned that the severity of infections as of now is generally mild.
Speaking about new Covid variants being traced, he said genome sequencing of samples in the west and south have shown that the new variants are not severe and are Omicron sub-variants. These are LF.7, XFG, JN.1 and NB. 1.8.1.
He also said there is no need for vaccination as of now when asked about the need for a booster dose .
Kerala has reported the highest number of active COVID-19 cases in the country, with 430 people currently infected, the central government data showed on Monday.
India currently has a total of 1,010 active COVID-19 cases, the data showed.
What did ICMR DG Say About Rising Covid-19 Cases?
Rajiv Behl was speaking of the different covid variants and said that LF.7, XFG and JN.1 are more prevalent, adding "Samples from other places are being sequenced and we will know in a day or two if there are more variants."
The ICMR DG said there has been an uptick in cases --first from the south, then west and now from northern India. All these cases are being monitored through the Integrated Disease Surveillance Programme (IDSP).
Besides that, ICMR's nationwide respiratory virus sentinel surveillance network is keeping a watch on emerging infections and pathogens, he said.
"Whenever cases increase, we look at three things. It's dependent on three factors with the first being how transmissible it is, conversely how fast the cases are increasing. Previously we saw Covid cases double in two days, but this time it is not that cases are increasing rapidly."
"Secondly, are the new variants evading our previous immunity? When new variants come, they evade immunity -- be it natural or from the vaccine. But there's nothing to worry about at the moment," Behl said.
He also said that the third factor is the percentage of severe cases in all Covid instances.
"Are we getting a very severe disease without comorbidities? As of now, the severity is generally low. There's nothing to worry about. We should be vigilant and we should always be prepared," the ICMR DG asserted.
Behl also informed reporters that the Union Health secretary chaired a meeting on Sunday that was also attended by the director general of health services and himself.
"We have been closely monitoring the situation. We should be vigilant at this moment, but there is no cause to worry. The general public should be vigilant. There is no need to take any such action as of now," he said.
The officer added that the WHO database has been showing that the new variants were not causing severe disease.
"People do not need to take any immediate action. They should follow normal precautions. So, there is nothing special to do right now."
Asked about the need for a booster dose, he said there is no need for vaccination as of now.
"India has the capability to make vaccines and if need be, we can make any vaccine in no time."
As of May 2025, the World Health Organization (WHO) classifies LF.7 and NB.1.8 subvariants as Variants Under Monitoring, not as Variants of Concern or Variants of Interest. But these are the variants that are reportedly driving the rise in Covid cases in China and parts of Asia.
