Cambodia’s director of dengue control at the Ministry of Health, Ngan Chantha, said on Monday that from January to September of this year, 12,392 cases of dengue fever had been reported and 54 children have died of the disease, Xinhua reports. In all of 2010, 5,497 cases of dengue and 37 child deaths from the disease were recorded, according to the news agency.
“More than 12,000 have been infected and 125 people have died over the past two months in Pakistan after coming down with dengue fever, a health department spokesman said Friday,” CNN reports (Habib, 10/1). Citing the same numbers, WHO spokesperson Tarek Jasarevic said the agency is providing support for “case management, community mobilization, vector control and public awareness campaigns,” according to the U.N. News Centre. “Last year, 11,024 confirmed cases of dengue fever and 40 deaths were reported in Pakistan, but this year the number of cases has climbed to 12,466,” the news service writes (9/30).
“An outbreak of dengue fever in Mandera, northeastern Kenya, is spreading fast, with at least 5,000 people infected within weeks, due to limited health facilities, a shortage of medical personnel and poor sanitation, officials told IRIN.” The news service writes, “A statement by the Ministry of Public Health and Sanitation on 26 September said four deaths from the disease had been confirmed but, according to Mandera residents, at least 10 people have died since early September when the outbreak started.”
In this GlobalPost opinion piece, Zulfiqar Bhutta, Husein Laljee Dewraj professor and head of the Division of Maternal and Child Health at the Aga Khan University Medical Center in Karachi, Pakistan, and Ciro de Quadros, executive vice president of the Sabin Vaccine Institute and former director of the Division of Vaccines and Immunization at PAHO, examine the need for a dengue fever vaccine as Pakistan struggles to curb an outbreak of the disease that to date has killed 60 people and has infected more than 8,000. “The need for a dengue vaccine is clear,” and “[w]ithout a vaccine to prevent dengue, we must redouble our efforts to effectively treat this infectious threat, starting with improving diagnostics,” they write.
Pakistan Officials Ask For International Assistance As Dengue Fever Outbreak Overwhelms Local Resources
BBC News reports on a continuing outbreak of dengue fever in Pakistan’s Punjab province, where “more than 8,000 cases of dengue fever have been reported … so far — 7,000 in Lahore alone — and the count continues to rise,” according to the Punjab health department. According to the news service, “Doctors say more than 30 people have died of the fever so far” in the province, and “[h]ealth officials estimate that more than 7,000 people are being tested daily for the virus — 300 to 400 test positive each day” (Haq, 9/23).
“On top of a raging insurgency and devastating seasonal floods, Pakistan is reeling from a particularly acute outbreak of dengue fever that has left local authorities scrambling to contain the epidemic” and has put a strain on the health care system, the Washington Post reports, adding that the disease “has already infected thousands across the country and killed as many as two dozen people.” Local government officials have “reacted frantically to the daily increase of cases with a series of measures including school closures, free treatment for dengue patients and large fumigation drives. But some say the response is inadequate and authorities should have focused more efforts on prevention,” the newspaper writes.
While the number of malaria deaths has fallen by one-fifth over the past decade globally, according to a report released by Roll Back Malaria on Monday, “India is still recording high numbers of deaths, which some experts say are underestimated,” Agence France-Presse reports. The WHO “says about 5,000 children and 10,000 adults die each year from malaria in India,” AFP reports, adding, “However a study published last year by the Lancet said there are more than 200,000 malaria deaths each year and that WHO’s reporting is flawed.”
“The government in Pakistan’s eastern province of Punjab is struggling to control a growing dengue fever epidemic, officials say,” and they “have warned that it threatens to affect other parts of the country,” BBC News reports. “Punjab Health Secretary Jehanzeb Khan said that this year more than 4,000 cases of dengue fever had been reported, a significant increase over previous years,” and at least eight people have died of the disease, according to the news service. Officials “say that the illness is thriving because of poor hygiene, an absence of control measures and the fact that recent heavy monsoon rainfall has lowered temperatures and provided lots of water — ideal conditions for dengue-carrying mosquitoes,” the news service writes (Khan, 9/13).
“In dengue-endemic areas such as South-East Asia, in contrast to conventional thinking, rural areas rather than cities may bear the highest burden of dengue fever,” according to a study led by Wolf-Peter Schmidt from the Nagasaki Institute of Tropical Medicine in Japan and published in this week’s PLoS Medicine, a PLoS press release states. The authors “analyzed a population in Kanh-Hoa Province in south-central Vietnam (~350,000 people) that was affected by two dengue epidemics between January 2005 and June 2008” and “found that at low human population densities, mostly in rural areas, dengue risk is up to three times higher than in cities, presumably because the number of mosquitoes per individual is higher in low-density areas,” according to the release (8/30).
Injecting mosquitoes with the Wolbachia bacterium “can block them from transmitting the dengue virus and help control the spread of a disease that kills 20,000 annually in more than 100 countries,” a team led by Scott O’Neill, a geneticist at the University of Queensland in Brisbane, reports in two papers published in Nature on Thursday, Reuters reports. The “researchers in Australia showed how female mosquitoes infected with the Wolbachia bacteria passed the bug easily to their offspring, making them all dengue-free,” according to the news agency (Lyn, 8/24).
