The tropical diseases that occur most often are Amebiasis, chagas disease, cholera, dengue fever,
filariasis, giardiasis, leishmaniasis, malaria, schistosomiasis, and also yellow fever.
Amebiasis can be prevented by following proper hand washing procedures, by boiling or drinking filtered water or
bottled water, by cooking your food properly, and also by avoiding fly-contaminated foods. The treatment for
amebiasis is usually metronidazole (flagyl) 750 mg taken 3 times each day for a total of 10 days and then
iodoquinol 650 mg 3 times a day for the next 20 days.
Chagas disease can be prevented by avoiding the assassin bugs also known as kissing or ruduviid bugs. They hide
in adobe hut structures or thatched roof or med dwellings. It is also wise to avoid having to receive blood
transfusions in Latin America. There is no treatment for chronic chagas disease but acute illness can be shortened
with nifurtimox which has some severe side effects to it. Two other medications that can be taken for chagas
disease in the acute stage is benznidazol or ragonil.
The best way to avoid getting cholera is to avoid eating raw or undercooked food and also avoid eating reheated
foods or seafood, especially ceviche. Vaccines are not recommended by the World Health Organization (WHO). It is
also wise to disinfect food and water. Treatment for cholera caused by Vibrio cholerae is to re-hydrate the
patient, and use antibiotics Cipro 1 gm as a single dose and Floxin 800 mg as a single dose, doxycycline,
tetracycline or furazolidone.
The only prevention for dengue fever is to avoid mosquito bites as much as possible by wearing clothing that
covers your body (long sleeves and long pants), sleeping in air conditioned rooms, or use a bed netting that is of
good quality. You can also use insect repellent. Treatment for dengue fever is to treat the symptoms as there is no
cure for dengue fever. Usually the symptoms will disappear after one week. It is important to rest, drink fluids to
re-hydrate, and to take pain medication.
| Are You Aware of the Neglected Tropical Diseases? Are these names familiar to you...leprosy, lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminths, or trachoma? If you answered, no, do not feel bad, because many individuals rarely hear mention of these tropical diseases anymore. The reason is that industrialized countries do not usually have to deal with these diseases anymore. They are the diseases that still ravage poor countries. Tropical Veterinary Medicine

biting midges, and by taking prophylaxis with diethylcarbamazine (DEC) weekly or monthly. Parsites must be cleared
first before using the preventative diethylcarbamazine. The treatment for filariasis is a high-dose of ivermectin
(200 micrograms/kg) for lymphatic filariasis; ivermectin (150 micrograms/kg every 6 months for 1 year, and then
annually for at least 5 years) for onchoceriasis; diethylcarbamazine (75 mg/kg total, but you must start out with
1/4 tablet per day and then you must slowly work up to 3 tablets 3 times a day for over a period of 3 weeks to
avoid anaphylactic shock from destruction of the worms. Another treatment is ivermectin (400 microgram/kg) as a
single dose for loiasis.

for a week - this medication is not available in the United States as well as tinidazole is not available in the
United States either another medication that is not available in the United States is furazolidone.
The only way to prevent leishmaniasis is to avoid sand fly bites. There are two types of leishmaniasis (visceral
and mild cutaneous) The usual treatment for visceral leishmaniasis is intravenous (IV) sodium stibogluconate
(Pentostam) 20 mg/kg taken each day for 30 to 40 days. The treatment for mild cutaneous leishmaniasis is to take
dapsone 100 mg two times a day for 6 weeks or you can take ketoconazole 600 mg each day for 28 days.

treatment for malaria is mefloquine, chloroquine, proguanil, quinine, quinidine, and artemisinin (qinghaosu).
You can avoid contaminated water by using chlorinated water or sea water as a preventative for schistosomiasis.
It is also wise to heat bath water to 122 degrees F for more than five minutes, or let water sit for three days in
a container. Treatment for schistosomiasis is a single dose of 40 mg/kg of praziquantil (Biltricide) a
The only preventative for yellow fever is to take a vaccine every 10 years and to avoid being bitten by
mosquitoes. There is no cure for yellow fever only supportive therapy for those who have contracted yellow
