New Delhi, May 3: The Indian Council of Medical Research (ICMR) has crossed over one million RT-PCR tests for COVID-19 on Saturday evening marking a big landmark, ICMR officials said.

"We have tested about 10,40000 tests till Saturday evening. In a few days, we have increased our testing capacity. ICMR has been doing more than 70,000 tests in the last two consecutive days," he said.

On Saturday, ICMR released that a total of 976363 samples have been tested till date. From May 1 till evening on Saturday, 1,37,346 tests were done.

The top three states which are doing vigorous testing includes--Maharashtra, Tamil Nadu and Rajasthan. As on date, these three states have conducted more than one lakh test respectively.

However, Andhra Pradesh, Uttar Pradesh, Karnataka and Delhi still need to ramp up their testing capacity.

ICMR has always emphasised that the confirmatory test for diagnosis of COVID-19 infection is RT-PCR test of the throat and/or nasal swab, which detects virus at an early stage. Recently, Dr GS Toteja, Additional Director General of ICMR had said that to contain coronavirus infection, RT-PCR tests must be continued vigorously as the principal diagnostic tests.

RT-PCR tests are now available in 310 government laboratories and 111 private set up across the country.

On Friday, the Centre informed that ICMR has ordered 21.35 lakh diagnostic kits. As on date, India has reported about 37,776 confirmed coronavirus cases and 1223 deaths.

Bengaluru, June 22: Even as the covid-19 positive cases are steadily increasing in Karnataka, an expert has claimed that community transmission has begun in Bengaluru and cases could keep rising over the next two months.

“If you look at the natural course of this virus across countries around the world, it is about six months. Now we’re in the fourth month. This will go on for another two months. It also sounds like this is the beginning of the peak. There is also a possibility of the number of cases going up from now on. Even across India, cases are increasing,” says Dr CN Manjunath, director of Sri Jayadeva Institute of Cardiovascular Sciences and Research and State Task Force member.

Besides the increase in number of cases, the virus is advancing silently, stealthily. A lot of people who are testing positive are asymptomatic. In areas like Padarayanapura, Nanjangud and many places in north Karnataka, there have been positive cases who have not had any contact with infected individuals. Some cases recorded in Bengaluru over the last two to three days have not had any contact with Covid-positive people.

Dr Manjunath adds: “We are in community transmission. This will happen because nature is ahead of everything. We have to take all possible precautionary measures at our command. This has to happen. Only then some kind of herd immunity will be developed.”

“We are expanding the guidelines of testing to include a large number of people to be tested. Now, according to the Indian Council for Medical Research (ICMR) guidelines, only symptomatic Influenza like Illness (ILI) or Severe Acute Respiratory Infection (SARI), or a person coming in contact with an infected person are being tested.

But since we have crossed 100 days in Karnataka from the first reported case and we’re getting cases with no travel history or contact with a Covid-positive person, we have to start random testing across the sub-group population. Only then will we understand the burden of the disease and what precautions need to be taken,” he says.
