This study was conducted in a tertiary care centre in Mumbai. Confirmed P. vivax cases were enrolled and studied for their clinical profile, and WHO severity parameters were tested for their frequency and association to mortality. Result. The most common presentation was fever followed by pallor. 26% of the cases satisfied one or more criteria of WHO severity parameters. 2 cases died; both had pulmonary edema and bleeding. The major predictor of mortality among these predefined severity criteria was pulmonary edema/ARDS. Patients with severe anemia, circulatory collapse, and repeated generalized convulsion had 100% survival rate. Leukopenia was present in 10% of the cases. Both cases with mortality had leukopenia.

Malaria still remains a public health problem in developing countries and changing environmental and climatic factors pose the biggest challenge in fighting against the scourge of malaria. Therefore, the study was designed to forecast malaria cases using climatic factors as predictors in Delhi, India. Methods. The total number of monthly cases of malaria slide positives occurring from January 2006 to December 2013 was taken from the register maintained at the malaria clinic at Rural Health Training Centre (RHTC), Najafgarh, Delhi. Climatic data of monthly mean rainfall, relative humidity, and mean maximum temperature were taken from Regional Meteorological Centre, Delhi. Expert modeler of SPSS ver. 21 was used for analyzing the time series data. Results. Autoregressive integrated moving average, ARIMA (0,1,1) (0,1,0)(12), was the best fit model and it could explain 72.5% variability in the time series data.
