increase in temperature to the increase in the number of malaria cases. Similarly, low temperature also
showed an increased number of malaria cases, though there was very minimal change in the minimum
temperatures (Fig. 1). There was a drastic decrease in the annual rainfall but the number of malaria
cases increased. Similarly, the number of diarrhoea cases was on the increase while the change in
temperature was minimal. Even for humidity, the observation was the same, i.e. the number of cases
increased, while there was minimal change in the humidity level. The rainfall was decreasing but the
cases were increasing (Fig. 2).
