This Cautionary Notice directed to Cruisers in Indonesia; Malaysia; Thailand; Philippines; Burma and Northern Territory-Australia. ( The Cruising Rally leaving Darwin in the next few days for Langkawi - Malaysia via Indonesia and Singapore included)


The Health Authorities of South East Asian Countries are reporting serious outbreaks

of Dengue Fever in epidemic proportions.

SINGAPORE: A strain of dengue new to Singapore is impeding efforts to stem the spread of the mosquito-borne disease that has infected hundreds in the affluent city-state this year, a top health official said Thursday.

Health Minister Khaw Boon Wan said the current rise in infections, including a record 210 cases last week and one fatality, evoked memories of a 2005 epidemic that killed 25 in the tropical island-nation of 4.5 million.

"I'm quite worried about the dengue trend," Khaw told reporters on the sidelines of an infectious diseases exhibition.

Authorities said earlier this week that Singapore recorded a nearly 50 percent increase in dengue infections in the first 4-1/2 months of this year compared to the same period in 2006.

Dengue cases reported from the start of January to May 12 rose to 1,488 — up from 993 in the corresponding period last year, the Health Ministry said.

The disease, which causes joint pain, high fever, nausea and a rash, is endemic to the region. In severe cases, it leads to internal bleeding and sometimes death.

Khaw said the emergence in Singapore of a different dominant type of dengue was compounding the problem.

"What is a little against us is because of the strain, the strain type. It is ... largely new to the population here," Khaw said. "It's troublesome because many people have no current, existing immunity."

The dengue virus now predominant in Singapore is believed to be the same as in neighboring Indonesia, and is different from the main active strain in Singapore over the past few years, according to local media reports.

Those previously infected with other types of dengue are not immune, and may even face a higher risk of complications when infected with a different strain, The Straits Times newspaper said.

Health officials have been combing public housing estates in search of mosquito breeding sites. Dengue-carrying insects can breed in tiny pools of water found in flower pots, discarded bottles or cans, or old tires.

The Health Ministry said the recent spike in infections is likely due to warmer weather during this period of the year, which is conducive for breeding mosquitoes and the spread of dengue.



Dengue fever outbreak kills 14 across Thailand

Thailand's Ministry of Public Health announced on Thursday that the number of dengue fever patients nationwide has risen to over 10,000 and 14 people have been killed by the dangerous disease this year.

Until June 7, a total of 11,574 dengue fever patients, most of them between 10-24, have been found across the country, especially in the central, northeastern and southern Thailand, a public health official said.

The high-danger season of dengue fever is July but earlier-than- usual rains has meant that dengue is a greater concern this year than before, the official was quoted by local radio FM 100 as saying, adding that the insurgency in the far South means that anti-mosquito measures are more difficult to apply.

More breeding grounds for dengue-carrying mosquitoes emerge during the rainy season, he explained, especially in the three southernmost provinces where heavier rainfall contributes to a higher population of mosquitoes than in the country's other regions.

The Ministry of Public Health has ordered health officials to work with local authorities to prevent the further spread on any outbreak.



Dengue fever has killed 44 people nationwide in Malaysia in the first four months of this year, an increase of more than 100 percent compared with the same period of last year, a health official said on Sunday.

The country saw 900 suspected dengue cases last week, a record high this year, Malaysian Health Ministry's Parliamentary Secretary Lee Kah Choon said.

The state of Selangor alone reported over 200 cases last week, followed by Kuala Lumpur and Pinang, he told local reporters in Pinang after launching a health campaign in the capital city of Malaysia's northern state of Pinang.

That could be attributed to the erratic weather conditions that encouraged breeding of aedes mosquitoes, he said.

Lee said the ministry was launching several health programs to increase public awareness on the danger posed by dengue, including fogging in high-risk areas.


Cruisers Info :-

The Mosquitoes carrying the virus are Aedes aegypti and A.albopictus - they both are most active late afternoon until the sun goes down. Long Sleeves, Long Trousers - 20% Deet - Stay clear of heavy vegetation. Don't get bitten !

A new Outbreak of a related disease is reported by the Jakarta Post - The area is close to the Sunda Straits - therefore should not affect the Cruising Rally on its way through Indonesia.

Chikungunya originally from East Africa has recently caused an epidemic outbreak on the island of

Reunion. This very painful disease is carried by the same mosquitoes that transmit Dengue Fever.

"Chikungunya spreads through village in Bandarlampung"

National News - May 30, 2007

Oyos Saroso H.N., The Jakarta Post, Bandarlampung

About 100 people in Bandarlampung have been affected by an outbreak of chikungunya, a usually non-fatal viral fever spread by mosquitoes.

The outbreak has been centered in the village of Langkapura in Kemiling district.

Most of those infected have not sought medical treatment because they cannot afford to go to a community health center or see a doctor.

Chikungunya, which is similar to dengue fever, is characterized by high fever and severe joint pain, or arthralgia, that can last for up to a week.

The virus that causes the disease is spread though the bite of either the Aedes africanus or the Aedes albopictus mosquito, which also can carry the dengue fever virus.

Febri, 30, a resident of Langkapura village, said she had suffered high fever and joint pain for the last 10 days.

"The doctors said I have chikungunya. The sad thing is that my husband and child are also infected ... my child even fell unconscious."

Nurdin, head of a neighborhood unit in the village, said the chikungunya outbreak started last month.

"Initially only dozens of residents were infected, now that number has jumped to about 100."

Nurdin asked the Bandarlampung authorities for help in dealing with the outbreak.

"Many of the sufferers are already better, but the number of new infection is still on the rise," Nurdin said.

He said authorities had only fumigated in the village once to kill the mosquitoes. "We want more fumigation."

Nuryahman, who staffs a mobile community health unit, said he had taken blood samples from 12 people and sent the samples to the laboratory of the Health Research and Study Agency in Jakarta.

"However, we have not yet received the results (of the lab tests)."

Bandarlampung Health Office head Reihana said Langkapura was particularly vulnerable to chikungunya outbreaks because of the poor sanitation in the village.

He also said much of the village was filled with bushes and water-filled potholes. "Such conditions are ideal for the mosquitoes to breed."

Chikungunya was first recognized in epidemic form in east Africa in 1952 and has continued to cause major epidemics in Africa, India and Southeast Asia.

Its name comes from the Swahili word "chikungunya", which means "that which bends up", referring to the contorted posture of patients afflicted with the disease as a result of the severe joint pain. "

Dengue epidemic,and it will get worse

By : Annie Freeda Cruez

KUALA LUMPUR: The country is facing a dengue epidemic. And it is expected to get worse due to global warming.

Last week, the number of Dengue cases breached the 1,000 mark for the second time in a month, signalling an epidemic.

A total of 1,044 cases were reported last week. The previous week, it stood at 1,116.

Between January and June, a total of 25,858 Dengue cases were reported nationwide compared with 16,808 cases during the same period last year.

The disease has claimed 56 lives so far this year compared with 46 during the same period last year.

Hospitals and health clinics have been put on alert and the government has ordered the National Dengue Operations Centre and all state and district operation centres to be open from 8am to 4.30pm.

Deputy director-general of Health Datuk Dr Ramlee Rahmat said: "It is partly due to global warming.

"We are going to see a rise in vector-borne and water-borne diseases."

He called on Malaysians to check the spread of the disease by destroying Aedes mosquito-breeding grounds and following the do’s and don’ts outlined by the department.

"It is not just the mosquitoes which are going to pose a threat to public health. We can also expect more water-borne diseases due to global warming."

At the recent global warming conference held here, scientists expressed concern that rising temperatures could have a huge impact on people’s health in the Asia-Pacific region, causing more of everything, from food poisoning to dengue and malaria.

The alarming rise in Dengue is also seen in Singapore, Indonesia, Thailand and some other countries in the region.

Selangor, with 9,137 Dengue cases, tops the list with the highest number of cases in the country followed by Federal Territory of Kuala Lumpur (4,548), Johor (1,685), Perak (1,555) and Kelantan (1,530).

Dr Ramlee said enforcement checks nationwide showed owners of houses were the main "breeders" of the Aedes mosquito, followed by construction sites, schools and factories.

Between January and June 30, the department issued 7,526 notices and 8,277 compound notices and collected RM1,185,040 in fines.

The public can contact the National Dengue Operation Centre by calling 03-88810200 or 03-88810300.
