Identification of hotspots, rate of doubling to determine lockdown

Identification of hotspots will be a crucial step in determining lifting of the lockdown at the national and regional level according to Raman R Gangakhedkar Head Epidemiology and Communicable Diseases at Indian Council of Medical Research ICMRThe first marker of control of virus spread is the rate of doubling time of number of patients turning COVID19 positive This formula may not be applicable at this point of time due to Markaz event It may be applicable in last week of lockdown he saidGangakhedkar while addressing a webinar said that India is not yet in community transmission stage India remains in imported kind of disease at this stage and people coming in their contact are getting infectedWhile the Markaz event has posed challenge and districts affected due to this are 200 but this would not be considered as community transmissionGangakhedkar who is also on the PM task force said that identifying hotspots areas with higher intensity of COVID19 positive patients is ongoing activity is one of the important steps in determining lifting of completepartial lockdown at nationalregional level Citing concern he said that the reason for worry is on availability of ventilators given the size of countryHe added that it is difficult to gauge the behaviour of people in lockdown given one of the rare steps taken to curtail the outbreak Over next three week the number of patient becoming COVID19 positive would help to understand if the lockdown becomes national level or becomes regional level 77 per cent of traffic has gone down in urban areasHe emphasized that breaking the chain of transmission is of utmost importance This can be done by following social distancing ensuring people stay at home physical distancing to be followed at workplaceThe Antibody test kit would be available by end of April following which testing would no longer be a big issue Once the antibody kits are available the test pace would also improve providing further clarity on the spread of the disease This would be beneficial from manufacturing industry perspective as wellHe added that there are kits under development wherein the test can be done in 1520 minutes time This test can be done easily outside One of the research organizations has developed this kit and validation is in progress If it works well then this can be offered to any Indian company for supplying kitsWhile the vaccines are under development prevention is the priority till then With the kind of strategy and steps followed in India there is less probability of requirement of cure for treatment in this cycle as steps for prevention are followed more religiously Gangakhedkar addedOn the transmission he added that breaking the chain of transmission is of utmost importance This can be done by following social distancing ensuring people stay at home physical distancing to be followed at workplace among other measuresIn India about 70000 tests have been conducted so far Gangakhedkar added that one needs to wait and watch if seasonality arrests spread of coronavirus Also current evidence doesnt indicate herd immunity is helping to arrest the outbreakThe contact tracing is extremely strong to ensure detection and at times the experience has been very hostile for people collecting samplesconducting test Responding to a question he said that the study on BCG vaccine is also farfetched approachOn vaccines he said that about 3 vaccines have moved to animal toxicity studies The government has ordered for 5 million antibody test kits They are equipped with 34 million PCR based antigen test as such However one needs to understand there is huge shortage of kits and other accessories to carry the test There are at least 23 Indian manufacturers whose kits are approved for PCR testThere are kits under development wherein the test can be done in 1520 minutes time These tests can be done easily outside One research organization has developed this kit Validation is in progress If it works well then this can be offered to any Indian company to supply the kitsOn the medication regime he said that HCQS is less toxic than chloroquine phosphate Evidence from laboratory studies indicates this works well against coronavirus but outcome of human clinical trials on large scale needs to be seenThe loss of smell can occur even in influenza cases also people have different sensitivity to different smell Thus the preference would be towards antibody test which are far more objective he addedThe current SOP is routine ICU management and ventilator to be provided In addition HCQS and Azithromycin would continue to be provided as two drugs in first line of treatment Booster Lopinavir is alternate regimen If any effective drug comes up in recent studies then ICMR would be quick to adopt it Gangakhedkar addedCatch up on all the latest Crime National International and Hatke news here Also download the new midday Android and iOS apps to get latest updatesThis
