title: Malaria in seasonal migrant population in Southern Gujarat, India.
abstract: Malaria in migrant workers is always a major problem to control due to their   temporary stay in shelters, and other operational constraints. Hence, a study was undertaken   in brick kilns in Bharuch district, Gujarat state, India to study the problem of malaria in the   work force. Mass blood surveys were carried out in 15 brick kilns. Blood slides were collected   from both febrile and afebrile cases. Positive cases were treated as per the national drug   policy and were followed up. Mosquito collections were carried out by pyrethrum spray   collection in early morning hours. Human blood index and sporozoite rates were determined   as per standard procedures. All age groups were found affected with malaria at brick kilns.   Prevalence of malaria was significantly higher in ≤ 14 years of age-group as compared to   adults. Post treatment follow up examination of patients revealed high malaria infection due   to non-compliance of chloroquine. The appearance of parasitaemia among Plasmodium   falciparum treated cases indicate the possibility of chloroquine resistance. The proportion of   P. falciparum was >50% in migrant population. In stable population in villages, overall decline   in malaria cases was observed in 2008-2010. The sporozoite rate of 4.2% in Anopheles   culicifacies indicates active malaria transmission at brick kilns. The investigation demonstrated   that suitable microclimatic conditions for malaria transmission exist in these areas during   hottest period. The district health department should consider these factors in planning   malaria surveillance and control. As current magnitude and diversity of population movements   in rural as well as in urban areas are unprecedented, this issue is worthy of attention.
