“Our main suspect behind the rapid increase in COVID-19 case is due to Omicron as most patients developed symptoms of the new variant,” he said.

According to him, at least 95 samples were sent to the National Institute of Biomedical Genomics in West Bengal’s Kalyani in December and another 224 samples were sent to the same institute in January.
The official said that the samples sent for genome sequencing in January were highly suspected for Omicron as majority of them were collected from returnees, who tested positive for COVID-19 on their arrival at Lengpui airport in Aizawl.
He said that Delta variant is still exists alongside Omicron as symptoms of Delta variant were still found in some patients.

Dr Rosangluaia, who believed Mizoram has already witnessed the third wave of COVID-19, said most patients these days developed less severe symptoms and loss of smell is less common, which were indicative of Omicron variant.
The community transmission rate now is not controllable by the imposition of lockdown, he said.
ZR Thiamsanga believed that negligence to COVID-19 Appropriate Behaviour, re-opening of churches and home isolation facility could be other reasons behind the high infection rate besides Omicron variant.
“It is verified that many people contracted the virus after attending church service, while others got infected from their relatives during home isolation,” he said.
