Government declares end of dengue fever outbreak, lifts alert status

The government declared the dengue fever outbreak over and lifted
the red alert status in 12 provinces, as the prevalence rate had
decreased to a baseline level.
Minister of Health Achmad Suyudi said the number of dengue
cases had been decreasing since mid-April.
"In May, there were only 506 cases with four casualties, far
below the 3,616 cases recorded a month earlier with 25 people
succumbing to the disease. We can see that the number has
declined significantly," Suyudi said on Wednesday.
He added the outbreak had slowed faster than the government
had expected. In May last year, 6,425 cases were recorded, of
which 78 died.
In February, the government placed Nanggroe Aceh Darussalam,
Jakarta, West Java, Central Java, Yogyakarta, East Java, Banten,
Bali, West Nusa Tenggara, East Nusa Tenggara, South Kalimantan
and South Sulawesi under extraordinary status due to the high
number of people affected by dengue fever.
The ministry recorded 59,321 cases and 669 deaths during this
year's outbreak.
Four distinct, but closely related, serotypes cause dengue,
with the Aedes aegypti mosquito the vector. All four serotypes,
DEN-1, DEN-2, DEN-3 and DEN-4, were found in dengue patients
here, said the ministry's expert staff on environment, health and
epidemiology, I Nyoman Kandun. Of these, DEN-3 is the most
virulent form.
Blood samples from 10 Jakarta hospitals revealed that two-
thirds of total patients were affected by the virulent DEN-3.
Dengue symptoms can range from mild, flu-like symptoms to its
most severe form, called dengue hemorrhagic fever, or DHF. DHF
causes damage to the blood vessels, leading to spontaneous
bleeding and shock, and can be fatal.
Recovery from an infection caused by a particular serotype
results in a lifelong immunity against that serotype, but
provided only a partial, transient protection against subsequent
infections by any of the other serotypes, he said.
During the outbreak, the government assigned 63 hospitals to
give free treatment to people with dengue fever. It also
allocated Rp 500 million to each "extraordinary" province to help
eradicate the virus.
"As of today, we have reimbursed Rp 1.045 billion (US$112,365)
in medical fees claimed by hospitals," said Suyudi.
Despite the normal status, the minister called on people to
maintain precautionary measures, as the country was not yet
dengue-free.
The government has long urged public participation in its
dengue eradication program through a change in household habits,
such as in draining open tanks, covering vats of bathing and
standing water and burying used cans -- locally called the 3M
measures -- to eliminate the breeding grounds of the Aedes
aegypti.
Dengue fever was first recorded in 1968 in Surabaya and
Jakarta, when it killed 24 people.
