New Delhi:Underlining the highly transmissible nature of Omicron and the preponderance of asymptomatic cases, the Centre has urged nine states and union territories to ramp up COVID-19 testing to ensure that infected people do not spread the virus to others. In a letter to Tamil Nadu, Punjab, Odisha, Uttar Pradesh, Uttarakhand, Mizoram, Meghalaya, Jammu and Kashmir and Bihar, Additional Secretary of Union Health Ministry Arti Ahuja pointed out a considerable decline in COVID-19 testing amid rising cases and positivity rate and said it is a "cause of concern".
In the absence of sufficient testing, it is rather impossible to determine the true level of infection spread in the community, Ahuja said in her letter dated January 5. "With the increased detection of the Variant of Concern (VOC), Omicron, and a majority of countries seeing multiple surges in cases despite high levels of vaccination, there is a need for continued vigil and efforts to prevent any deterioration of the COVID-19 scenario.
