Delta-Omicron combination might sustain 3rd Covid wave in Kerala: Experts concern caution



KOCHI: With the state apparently observing the beginning of the 3rd Covid wave, the sharp rise in the variety of instances reported daily might suggest the visibility of the extremely transmissible Omicron variation of the coronavirus in the populace though the wellness authorities are yet to verify area transmission.

Experts state a mix of the Delta variation, which was the factor for the 2nd wave, as well as Omicron might sustain the rise. 

Supporting that debate, the variety of Omicron instances has actually increased with 280 instances taped in the state till Thursday.

That might not be a precise number taking into consideration the abrupt rise in infections as well as the energetic caseload. The examination positivity price (TPR) that stood at 4.38% last Friday has actually increased to 6.8%.

“It is known that the transmissibility of the Omicron variant is very high compared to that of Delta. So Kerala can expect a huge rise in daily Covid cases. Over the past few days, the TPR and the number of cases have gone up. At this stage, we cannot exclude the presence of Omicron in the community. However, population immunity is the key, and since the Delta wave, Kerala has come a long way in terms of vaccination coverage,” stated Dr Padmanabha Shenoy, immunologist as well as public wellness specialist.

Experts additionally think that the variety of Covid examinations for presumed instances has actually gone down because of the present influenza period.

Though Omicron signs and symptoms resemble that of cold, researchers throughout the globe have actually alerted individuals not to take the infection gently.

“A lot of general flu cases are seen at hospitals these days, but not all are getting tested for Covid. So we don’t know how many of the cases reported here are caused by Omicron. Since we are staring at the third wave, it is important that people with Covid-like symptoms get tested and stay in isolation. But it might be to our advantage that a large proportion of the country’s population has acquired immunity through infection rather than through vaccination.,” Dr Shenoy stated.

According to Dr Dipu T S, an associate teacher with the inner medication division of Amrita Hospitals in Kochi, the winding down vaccine-induced resistance of the area can be reclaimed to a degree with the booster dosage. 

“By the end of six to nine months after vaccination, the vaccine-induced immunity wanes. At that stage, the number of at-risk population — people at risk of getting the infection again —would rise. With the third dose of the vaccine, we can target those facing the risk of reinfection and breakthrough infection,” Dr Dipu stated.

The transmissibility of Omicron is 4 times that of Delta, he mentioned.

“So the possibility of infection is very high even with a short interaction. When the infective index goes up, the number of people getting infected at a given time would be massive. Vaccination will definitely help. ,” he stated.
