In an earlier statement Punjab Director General Health, Dr Aslam Chaudhary had revealed that since July six cases of dengue are reported in Lahore. Medical experts believe the on going monsoon season may convert dengue into an epidemic since rain water ponds can serve as hatcheries for dengue carrying mosquitoes. Mayo Hospital Microbiology Head of department Dr Tayyaba said dengue may return with high potency since carrier mosquitoes breed and grow in clean stagnant water and rain water ponds can cause the spread of dengue mosquitoes. However, she said, malaria could also rise.
