The incidence of dengue fever was high in Rawalpindi [30.2%] and Chakwaal [30.1%]. The most common clinical manifestations were high grade continuous fever [>10[degree]F] seen in 88.4% [n=92], followed by retro-orbital headache 65.3% [n=68], epigastric pain 65.3% [n=68], arthralgias 63.4% [n=66] and myalgias 50% [n=52]
