The 100-odd pattern she collects is a small fraction in Tamil Nadu’s excessive testing numbers. On November 5, Tamil Nadu examined a complete of 10 million folks (10,052,393) within the state with extra dependable RT PCR (Reverse transcription polymerase chain response) take a look at, the one state in India to have performed so until date. On November 1, it crossed the 10-million mark of the variety of individuals examined in all.

In July, the common every day instances peaked, however since October there’s a downward pattern in new optimistic instances. “We’re trying to find the virus and chasing it,” well being minister C Vijayabhaskar has stated typically.
Tamil Nadu was capable of obtain the fete due to higher RT-PCR services and affected person monitoring system due to its previous efforts in AIDS and H1N1 management. For Covid-19, the state well being division simply added surveillance and testing to the present system.
One such measure was roping in laboratory technicians, like Sugitha who’s skilled to gather oral swabs to check for tuberculosis (TB). Sugitha joined the company in December 2019 below the Nationwide TB Elimination Venture. She was introduced into the Covid-19 workforce in April.
The community is introduced collectively like a well-oiled machine by door-to-door enumeration, fever camps and residential quarantine and isolation monitoring system (HQIMS). “The state supplied 100-crore for strengthening our house surveys and HQIMS,” stated Larger Chennai Municipal Company commissioner G Prakash.
Covid detection begins with the fever surveyors like J Sivalingadurai (the company’s paid volunteer since April 16) going door-to-door. Every surveyor is assigned 150 properties. Sivalingadurai’s assigned households are in a fancy multi-storey house on Previous Mahabalipuram Highway in south Chennai, the place techies from throughout India and overseas dwell. He visits every house every day and asks the identical set of questions: “How are you feeling in the present day? Do you have got a fever? Are you able to scent?”
His intrusion is essential in figuring out a number of the virus. “Bro!” one girl techie exclaimed in reduction as quickly as she noticed him at her door on June 26 morning. “Verify our temperatures,” she had advised him. The lady in her mid-20s and her two roommates had developed fever the earlier evening. Since they’d popped paracetomols, the thermal scanner confirmed no fever. “In the event that they hadn’t advised me about their fever, I wouldn’t have identified,” stated Sivalingadurai, including going every single day helps in constructing belief.
The lady techie was despatched to a fever camp. She examined optimistic and moved to a quarantine facility. Her roommates turned unfavorable however have been placed on house quarantine. Fever camps turned an important hyperlink in virus management measures. Up to now, three,378,398 folks have attended the camps in Chennai with 15% optimistic fee.
The fever camps have been elevated to 550 in Chennai from 300 in Could. “We replicated Chennai’s mannequin, significantly the fever camps in Madurai and it labored in decreasing the virus unfold,” stated well being secretary J Radhakrishnan.

The state now has 203 authorities and personal testing services.
Because the instances have elevated, testing at labs has risen by nearly 20 instances. At a Chennai non-public lab, the lead microbiologist, who didn’t want to be named, began by testing 50 samples a day in mid-April which elevated to 800 in July and now she checks round a 1,000 samples.
“Within the early days, I used to say a prayer for each affected person’s pattern tube I held,” she stated. “Now we’ve got reached a saturation level, we really feel impartial.” Contained in the bio-safety cupboard, she opens the pattern vial for extraction and masses it into the RT-PCR machine. It takes 45 minutes to course of a batch of 12 samples. Microbiologists work in three shifts to maintain testing 24×7 at this lab. The ultimate step within the testing course of is the (PCR) machine detecting if the particular SARS-CoV-2 genome is current within the pattern (if the detected affected person is optimistic). It takes between 24 to 48 hours earlier than a affected person receives their end result.
If the report is optimistic, a sanitary inspector (SI) inspects the affected person’s house to certify if they’ve a separate room and bathroom for house quarantine.
