KARACHI - Deadly malaria is on the rise in the metropolis and health experts have warned citizens to be conscious and keep clean their houses. Malaria, though preventable and curable, causes more than 50,000 deaths each year in the country mostly in infants, children and pregnant women, which is point of concern for the authorities concerned of the country.As per statistics of the global burden of malaria, globally more than 500 million malaria cases are reported every year; a child dies of malaria every 30 seconds, while more than one million people die of malaria every year, mostly infants, young children and pregnant women and most of them in Africa. As per statistics given by the WHO, approximately, 40 per cent of the world’s population, mostly those living in the world’s poorest countries, are at risk of malaria. The health experts, working in the city, strongly advised the citizens to adopt precautionary measures against the disease.Talking to TheNation, , the expert in mosquito species and Professor of Department of Geography, University of Karachi Prof Dr Jamil Hasan Kazmi asserted that the effective malaria roll back programme is essential to prevent the people of the province in this situation.Talking about the transmission of the malaria, caused by parasites of the species plasmodium that are spread from person to person through the bites of infected mosquitoes, he said that it could be transmitted to people of all ages. He said, “There are four kinds of human malaria – Plasmodium falciparum (PF), P Vivax (PV), P Malariae, and P Ovale while PF and PV are the most common kinds in the country. PF is by far the most deadly type of malaria infection. Malaria transmission differs in intensity and regularity depending on local factors such as rainfall patterns, proximity of mosquito breeding sites and mosquito species. Some regions have a fairly constant number of cases throughout the year – these are malaria endemic – whereas in other areas there are “malaria” seasons, usually coinciding with the rainy season.”It is pertinent to mention here that, as per rough estimate, around 500,00 malaria cases are reported annually in Pakistan, while Sindh and Balochistan are more affected provinces of the country.Talking about the fatality of the disease in children, he stressed the need for screening of blood so that the infected patients could properly be cared and cured. The central leader of Pakistan Medical Association (PMA) Dr Qaisar Sajjad stated that malaria is on the rise in the city, which needs proper attention of the authorities concerned.. Authorities concerned said that the citizens are required to remove all such places where dengue and malaria mosquitoes breed, he said, adding that this is the only solution to control the spread of disease in the City.It is also worth mentioning that, according to a health organisation, malaria causes an average loss of 1.3 percent annual economic growth in countries with intense transmission. When compounded over the years, this loss has lead to substantial differences in GDP between countries with and without malaria. 
Malaria traps families and communities in a downward spiral of poverty, disproportionately affecting marginalized populations and poor people who cannot afford treatment or who have limited access to health care.
