The Corporation has held 2,430 monsoon medical camps since 15 October and has 3,703 workers going door to door for dengue, each covering 80 to 100 houses a day.
Seventy-one camps on a single Tuesday. That was the Greater Chennai Corporation’s count for 10 November, when 2,203 people were seen at its monsoon disease medical camps, according to its press release No. 665 that evening.
Since the camps began on 15 October, the total has reached 2,430 camps and 81,199 people. The pace has eased with the rain. On 4 November, the Corporation said, it held 103 camps in one day and treated 3,685 people, which put the tally then at 1,970 camps and 66,645 people.
Dengue teams are back on the streets
The bigger number in the latest release is the dengue workforce. Civic health staff number 3,703 field workers on this job, and each one is expected to survey 80 to 100 houses a day, asking about fever and looking for mosquito breeding. In its own count, 372 locations across the city have been marked as hotspots and are getting intensive treatment, including fogging. The release does not give a citywide total of fever cases or of breeding sources found, and it does not break the work down zone by zone, so there is no way yet to tell from the Corporation’s figures whether Tiruvottiyur in the north or Sholinganallur in the south is carrying more of the load.
Schools were swept first. On 6 November civic officials said it had run an anti-mosquito drive across 1,051 school campuses and removed 2,147 kg of waste from them. A day earlier it announced that HPV vaccination for girls aged 14 and 15 was under way in Chennai schools, a separate programme that is running through the same weeks.
No helpline number is listed in the latest release, so residents with a fever case or a breeding spot to report will have to go through their ward office.
Water is being tested at the tap end
Monsoon illness in Chennai often starts with water, and the Corporation has stepped up residual chlorine checks. On 10 November its staff tested 1,166 samples, 807 of them from public water points and the rest from pumping stations, Metro Water lorries, tanks and tankers. A day earlier the count was 515, drawn from 42 pumping stations, 340 public water points, 52 Metro Water lorries, 71 tanks and 10 tankers. Every sample was found chlorinated, the release says, which is the check that matters most after flooding.
For disinfection it has 53,405 kg of bleaching powder in stock and plans to buy another 150 tonnes for the rest of the season.
One more health centre in Thiru Vi Ka Nagar
Those camps run alongside a fixed network that grew by one this week. On 10 November a new urban primary health centre in Thiru Vi Ka Nagar zone, on VV Koil Street and built for ₹2.30 crore, opened together with two school buildings in the same part of north Chennai. The Corporation already runs 140 urban primary health centres, 200 urban health and wellness centres, 16 community health centres, three maternity hospitals and one infectious disease hospital, 360 institutions in all, plus 10 dialysis centres.
Camp locations are chosen from areas that saw waterlogging and rain, the Corporation said on 4 November, at about 100 camps a day then.
