Key Points
- Over 1,200 active Covid-19 cases reported across India.
- New JN.1 variant detected in Kerala, Maharashtra, Delhi, and Uttar Pradesh.
- BHU scientist predicts cases could peak in the next 3-4 weeks.
- Sewer sample testing in Varanasi to track community spread.
- Ongoing genome sequencing to monitor new variants JN.1 and NB.1.8.
Varanasi: India is witnessing a concerning rise in Covid-19 cases, with active cases surpassing 1,200 across multiple states. The latest surge is being driven by the emergence of new variants, particularly the JN.1 sub-variant, which has already been reported in Kerala, Maharashtra, Delhi, and Uttar Pradesh.
JN.1 Variant Spreading Rapidly
Professor Gyaneshwar Choubey, a leading scientist at Banaras Hindu University (BHU), has sounded the alarm over the rapid spread of the JN.1 variant. According to Prof. Choubey, this sub-variant, which was first detected in Singapore, Hong Kong, and the United States, is now making its way through India. He cautions that, based on the current rate of increase, India could see a peak in cases within the next 3 to 4 weeks.
Comparing Covid Waves: Faster Spread Expected
Prof. Choubey explained that each wave of Covid-19 has had a different infection period:
- First Wave: Lasted about 60 days, slowed by strict lockdowns.
- Second Wave: Peaked within 21 days, with a rapid rise in cases.
- Third Wave: Remained active for 28 to 32 days.
He warns that the JN.1 sub-variant, a form of Omicron, could spread even faster, potentially reaching its peak in just 21 to 28 days before cases begin to decline.
Tracking the Threat: Sewer Sample Testing in Varanasi
To better understand the spread and potential danger of the new variants, Prof. Choubey’s team at BHU is ramping up research efforts. Genome sequencing remains crucial for monitoring mutations and identifying emerging threats. During previous waves, genome sequencing helped detect new variants such as Alpha, which contributed to widespread community transmission and a spike in fatalities.
In the coming days, BHU scientists will collect and analyze sewer samples in Varanasi. This method can reveal the presence and quantity of the virus in the community, offering early warnings about potential outbreaks and the extent of community spread.
Ongoing Research and Public Vigilance
Research is ongoing to determine how dangerous the new JN.1 and NB.1.8 variants might be. The findings from genome sequencing and sewer testing will help authorities assess the risk and prepare an effective response.
