Info on dengue is easily accessible on the Internet. Info regarding the risks, transmission,
consequences of infection and methods to protect yourself (and your family) are all well
documented. But there remains a large amount of misinformation and ignorance on this
critical health issue.
If you suspect a Dengue infection the most important steps are:
1. BLOOD TEST: If you suspect you have dengue (sudden onset of fever and first symptoms
& usually a headache and joint aches & pains) GET A BLOOD TEST IMMDEIATELY.
You need to know your baseline thrombocyte and hematocrit levels at the outset and
keep an eye on them in subsequent blood tests. If your thrombocyte level – normally
150,000 to 400,000/ul - drops below 100,000/ul or your hematocrit increases by more
than 20% you are in the DHF risk zone. In cases of confirmed dengue fever you will need
blood testing twice each day and oral/intravenous fluid replacement so hospitalization
is STRONGLY RECOMMENDED once the disease is confirmed as intravenous and
oral fluids and daily blood monitoring are required.
2. There are 4 strains of the disease. If infected by any strain you will have lifetime immunity to that
particular strain… and that strain ONLY – THIS IS THE HIDDEN DANGER OF DENGUE. If
subsequently you are infected by one of the other strains your immune system will react to
the new infection as if it is the same as the previous strain and use that antibody to fight the
new infection - without making a new antibody to fight this different strain - this is where Dengue
Hemorrhagic Fever (DHF) or Dengue Shock Syndrome (DSS) become real possibilities. DHF and
DSS are life-threatening even to healthy individuals. Mortality from Dengue Fever is 1 to 2% but
mortality after the onset of DHF jumps as high as 30%!
As to the potency of DHF just last week Michael Ruslim, President Director of Astra and an otherwise
healthy 56 year-old, sadly passed away in Singapore due to complications from DHF. He fell ill on 16
December, was transferred to Singapore on 18 December, and passed away on 20 December - just 4
days after first being hospitalized.
It is also reported that in Indonesia the real death rate due to dengue is under-reported as many deaths,
especially young children in poverty ridden areas, go unreported.
3. Dengue is transmitted mainly by the Asian Tiger Mosquitoes - aedes aegyptii and aedes albopictus.
These mosquitoes are active mainly during daylight hours BUT if they enter a house they will also bite in
the evenings.(The anopheles mosquito which carries the malaria parasite on the other hand bites from
dusk until late at night)
4. Protection against mosquitoes:
Insecticides: We have seen too much indiscriminate fogging in Indonesia and this is allowing the
mosquitoes to become resistant to many of the insecticides used. Also - some space sprays marketed
here contain insecticides not permitted for indoor use in western countries. Another problem with space
sprays is they only last a short time and then the mosquitoes will enter the house again soon afterwards.
Mosquito coils and the electric vaporizing devices have very limited coverage area and are prohibited for
indoor use in many western countries.
Commercial insect repellants sold in the local market have limited effectiveness and their us is only
recommended when venturing outside – they are not recommended for 24 hour protection.
Plants such as lavender, citronella, basil and rosemary are avoided by mosquitoes but there effective
range is only a meter or two which means you would have to literally fill your house and garden with them
to get effective protection.
Traps and zappers use light in the UV frequency to attract insects as the light represents a "safe" haven
for them - unfortunately the female mosquitoes entering your house are driven by a compulsion to feed on
blood in order to obtain the protein they need to produce eggs - they are NOT seeking a "safe" place.
Research has shown that traps normally catch the mosquitoes AFTER they bite and do not significantly
reduce biting frequency. In any case they are mainly effective only after dark as the lamp has limited
visibility to insects in daylight hours - the hours when the dengue carrying mosquitoes are seeking a
host. In summary these devices, although effective in trapping & killing insects, are only useful in a dark
room where humans are not present – rather pointless in terms of protection.
Fortunately there is now a safe and effective solution which continuously protects indoors areas against
mosquitoes. The product marketed by my company has been approved by EPA and FDA in the USA
over 40 years and is approved by the Indonesian Departments of Agriculture and Health. It is now being
used in an increasing number of expat homes in Indonesia as well as restaurants, offices, schools,
hotels, hospitals etc - wherever mosquitoes are a problem.
Anyone interested in complete protection for your home or business against disease carrying
mosquitoes please contact me by e-mail or personal message through these forums and I will forward
some information on our product. If you need more immediate attention (your house or business has
been taken over by mosquitoes) just call me on 081910491376
I wonderred what this was all about, it's an advertisement, dishonestly disguised IMHO and in the wrong thread, as some friendly advice despite the topic being fairly extensively coverred in previous posts within the forum... sneaky mate! and a -1 for you!
