Ahmedabad: At a time when the Ahmedabad municipal corporation (AMC) has intensified efforts to eliminate mosquito-breeding sites under its 'Malaria-free Gujarat by 2022' campaign, more than 1,000 cases of malaria were reported from June 1 to July 8 at AMC-run hospitals in Ahmedabad alone. Sources said that in all the cases, the culprit bacteris was plasmodium vivax .
So many malaria cases prior to monsoon is itself unusual but what has civic authorities worried is that most patients were cases of relapse of malaria infection. This indicates that treatment of these malaria cases in the city had been discontinued midway.
Dr V K Kohli, assistant entomologist, AMC, said that in summer, relapse of plasmodium vivax-induced infections often occur due to the evolutionary adaptation of the parasite. "The fever often occurs in people with low immunity but the main reason is incomplete treatment," Dr Kohli said.
He further said that once the fever symptoms subside, radical treatment through a drug known as primaquine is needed, which needs to be administered for 14 days. "This helps prevent a relapse. Howvever, the drug has a haemolytic side-effects and, therefore, cannot be given to infants and pregnant women," Dr Kohli said.
