Pakistan is hit by dengue fever epidemic
By M Ilyas Khan BBC News, Islamabad
Mosquito Dengue-carrying mosquitoes are thriving in Pakistan's
monsoon, which has provided them with cooler temperatures and lots
of water
The government in Pakistan's eastern province of Punjab is
struggling to control a growing dengue fever epidemic, officials
say.
They have warned that it threatens to affect other parts of the
country.
More than 4,000 cases of dengue fever have been reported in the
past two months, officials say, and at least eight people have
died.
While the disease is not new in Pakistan, experts say it has
spread fast and may reach crisis proportions.
They 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.
Dengue fever is a tropical disease caused by mosquitoes that breed
in stagnant water.
'Choked' sewage system
According to the World Health Organisation, the incidence of death
among infected patients is 4%.
The first case of dengue fever in Pakistan was reported in the
southern port city of Karachi in 1994.
Lahore street (August 2011) Lahore is a large city with poor
hygiene - all of which adds to the dengue problem
The province of Punjab - particularly its capital, Lahore - have
seen a growing number of cases since 2007.
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.
The eight people who have died so far include Ataullah Siddiqui,
head of the provincial department for minerals and natural
resources.
Mr Khan said more than 3,500 infected people live in Lahore city.
The head of the city's Jinnah Hospital, Dr Javed Akram, told the
BBC that there are several reasons why the virus is concentrated
in Lahore.
"It's a large city with poor public hygiene," he said.
"We have also had heavy rain for the second year running. In many
areas the sewerage system was choked, creating water ponds.
"The city also has vast open spaces and public parks where water
has accumulated. In addition, the rains have brought down
temperatures by several degrees, creating ideal conditions for the
dengue mosquitoes to breed."
Dr Akram says the spread of the disease to other parts of Punjab
province has been caused by the government's failure to announce
and enforce travel restrictions and its failure to quarantine
affected people.
"In the absence of these measures, we expect a greater epidemic
next year," he said.
Officials say the provincial government has set up a telephone
helpline and issued pamphlets to create awareness about the fever.
The government has also banned morning assemblies in schools for
two months to prevent children's exposure to mosquito bites.
It is now considering a 10-day closure of schools.
Meanwhile, a team of doctors from Sri Lanka is expected to arrive
in Lahore today to help combat the epidemic.
