The Expert Committee Report-1995, recommended various parameters for identifying worst malaria affected segments in rural areas, which are mainly based on slide positivity rate (SPR). A analysis of the epidemiological data of Uttar Pradesh was carried out in different settings to study the sensitivity of SPR in identifying high risk areas. The validity of using SPR in the entire range in all settings is examined and appropriate corrective measures suggested.

The study was carried out in Allahabad district, (Uttar Pradesh) with 260 spraymen as test subjects and 50 persons as controls from a sprayed and unsprayed village respectively. Majority of the spraymen (44%) had worked for 3-4 years (seasons) and 31% had worked in the programme for 5-10 years. The spraymen were relatively healthy with no complaints in 77% whereas the figures were 76% for the Community living in the sprayed village, and 50% for the Community in the unsprayed village. A comparison of the biochemical parameters revealed lowered Cholesterol more than 150 mg % in 38% of the spraymen and 58% had altered A:G ratio. Other biochemical estimations were not significantly different from the control population. The mean residue of Alpha, Beta and Gamma Isomers and the total Alpha, Beta and Gamma isomers were 0.0317, 0.2254, 0.0288 and 0.2859 mg/1 respectively; the corresponding mean values in the control population were 0.0211, 0.1112, 0.0197 and 0.1520 mg/1 respectively. The values in spraymen were twice those of the general population. A significant association (p < .05) was observed between their length of exposure and the levels of Cholesterol and HCH isomers in blood of spraymen. No significant morbidity was evident in spraymen due to HCH exposure.

The study was carried out on 186 professional blood donors. A detailed-socio economic profile of these donors was taken and the serum was tested for HBs. Ag. Majority (63.4 per cent) of the donors were in the age bracket of 30-40 years with an average age of 34 years. About 83.3 per cent were illiterate and belonged to the lowest rung of the socio economic scale. The average length of blood donation was observed to be 4 years with blood letting frequency of 4.4 within a stipulated period of three months. Most of them were anaemic with an average haemoglobin level of 8.2 gm per cent. The HBs Ag prevalence was observed to be 15.59 per cent. HBs Ag positivity was found to be significantly associated with the length and the frequency of blood donation (P less than .05). Remedial measures for prevention of viral hepatitis-B through professional blood donors was emphasized.
