Alarming 80% rise in dengue cases in 2013

New Delhi: Dengue cases have risen alarmingly across the country this year, with data showing an 80% rise in the disease till July 31 as compared to the same period last year.
India has recorded 15,983 dengue cases so far in 2013 as compared to 8,899 cases in the corresponding months last year, latest health ministry data shows. But the good news is, while the cases have risen sharply, fatalities have actually declined — 56 as compared to 76 last year.
Kerala reported most dengue cases at 5,801, followed by Karnataka (3,775), Tamil Nadu (3079) and Maharashtra (961) till end-July. Delhi witnessed a sharp rise in cases over the last few weeks, with the total this year touching 54. No one has died due to dengue in the capital so far.
‘Several factors for spread of dengue’
“There is no single reason for the increase in dengue cases. It is governed by various man-made and environmental factors including unprecedented growth in population, unplanned and rapid urbanization and inadequate waste management,” union health minister Ghulam Nabi Azad stated in a written reply in the Lok Sabha on Tuesday.
Increasing mobility of the population and poor infrastructure to monitor mosquito breeding were some other reasons cited by the health minister. Azad said guidelines for clinical management of dengue cases have been sent to the states for circulation in hospitals and rapid response teams have been formed.
Dengue, termed by many experts as the world’s most rapidly spreading mosquito-borne viral disease, is caused by four serotypes. While type I and III are milder in nature causing classic dengue fever and fever without shock, respectively, dengue type II and IV are considered deadly. These cause fever, bleeding and a drop in platelet count. Researchers say severe dengue cases, dengue hemorrhagic fever and dengue shock syndrome, started showing up in India since 1988.
“A reason behind the increased frequency could be the presence of many strains of the virus. It exposes people already infected to become susceptible to infection as they are not immune to all the subtypes,” said Dr Ekta Gupta, clinical virologist at the Institute of Liver and Biliary Sciences (ILBS).
Experts say construction sites are a major area of mosquito-breeding followed by government buildings and water tanks. “In Mumbai, the municipal body, charges heavy fines if mosquitoes are found to be breeding at a site. The building’s completion certificate is stalled till the fine is paid. Similar steps should be taken in cities like Delhi,” said Dr Jagdish Prasad, director general of health services.
