CONSIDERING the fact that standing water after monsoon downpours provides an ideal breeding ground for mosquitoes, including those that transmit the dengue virus, this is the right time to review measures to combat the infection. Dengue fever is a global threat; the World Health Organisation says that 2.5 billion people may be at risk from the virus. In Pakistan, dengue epidemics have been occurring regularly since 2006, while as per a report in this newspaper, a study based on data provided by the Punjab health department says that a new strain of the virus has been detected in the province, and there is danger of an outbreak next year. Lahore is, apparently, most at risk. In fact, health and administrative authorities across Pakistan must raise their guard and take precautionary steps before the high-risk dengue season starts in October.

WHO recommends that the best way to combat dengue is to target the mosquitoes that transmit the virus. The global body suggests that proper disposal of solid waste, better water-storage practices and spraying areas where mosquitoes breed should be ensured to prevent the spread of dengue. Bearing in mind our previous experiences with the virus, as well as the information that has emerged from Punjab, we must ask if the health infrastructure can meet the challenge. Hospitals should be ready to set up dengue wards while a steady supply of platelets must be ensured for those who develop haemorrhagic fever. Local authorities must also drain pools of stagnant water and spray areas where mosquitoes breed. Many local administrations have been lax in this regard. No negligence can be allowed. Public-awareness campaigns informing the people about precautionary steps as well as identifying dengue symptoms should be initiated.
