Live updates: follow the latest news on Omicron
The rapid increase in cases — India reported at total of 27,553 new cases two weeks earlier — is in line with a worldwide surge attributed to the highly transmissible Omicron variant of coronavirus.
India has confirmed only 5,733 infections caused by Omicron since the first case was detected in early December, but experts say it is a massive undercount.
“The spread cannot be prevented as it is a highly infectious variant. It has happened all over the world,” Dr Sanjay K Rai, an epidemiologist practising in Delhi, told The National.
The country’s overall Total Positivity Rate — the number of tests returning positive — stood at 14.78 per cent on Friday, with some remote areas reporting much higher rates of infection.
Upper Siang district in north-eastern Arunachal Pradesh state reported a 75 per cent positivity rate — the highest in India. Lahaul and Spiti, the remotest district in the state of Himachal Pradesh, had the fourth-highest positivity rate in the country, with 41 per cent.
Remote districts in the north-eastern state of Assam also reported a sudden surge in infections, with a 10 per cent positivity rate. In bordering Tripura state, the test positivity rate rose to 9.18 per cent this week from 0.69 per cent on January 1.
In Mizoram, also in the north-east, 70 per cent of new cases are being reported in rural areas, said Dr Pachuau Lalmalsawma, state officer for the federal government’s Integrated Disease Surveillance Programme.
“There is a drastic increase in cases, particularly in rural districts, in the last week. Earlier, 50 per cent of the total cases were in the capital Aizawl but now 70 per cent of the cases are in rural areas. But there is no case of Omicron yet,” Dr Lalmalsawma told The National.
“These are all Delta cases, but we fear Omicron [may enter] any time in the country, transmitted from local tourists,” he said
The Delta variant drove India’s devastating second wave in April and May last year.
The second wave overloaded the healthcare system, with the number of patients requiring treatment or admission to hospital, leading to severe shortages of beds, oxygen and medicines.
Dr Lalmalsawma said the hospital admission rate was lower now as many of the patients had been vaccinated and were recovering at home.
India has administered 1.5 billion doses of Covid-19 vaccines so far, with 63.6 per cent of the adult population fully vaccinated with two doses and 88 per cent having received at least one dose.
Dr Rai said the severity of the new wave would be reduced by the high immunisation rate as well as the milder symptoms caused by the Omicron variant.
“We anticipate the [daily] number of cases may go up, may cross 400,000, but the impact will be low as it is much milder than Delta,” he said.
India last reported a similar daily case count on May 17, with 263,045 new infections and 4,738 deaths. On Friday, the health ministry reported about 300 deaths.
