The Tropical Diseases F.A.Q.

Monday, February 11th, 2008

There are many questions regarding tropical diseases due to the extensive International travel. Passengers, whether they are business or pleasure, want to know what tropical diseases they may encounter at their destination and how to prepare for them. Here is a listing of popular questions regarding tropical diseases and the answers to them.

What is a “neglected tropical disease”?

Neglected tropical diseases are called that because they occur in the most impoverished populations of the developing world and are thus neglected because their governments cannot afford to treat the people who contract them. They do not normally flourish in areas where there is economic or healthcare support so they are isolated to the remote, rural, urban slums or conflict zones of developing areas of the world. They go mostly unnoticed by the more economically stable countries.

What exactly is dengue fever?

Dengue fever is a viral tropical disease transmitted by the bite of the Aedes mosquito that has been infected with one of four dengue viruses. The symptoms are flu-like and the disease is prone to be contracted by infants, young children and weakened adults.

What is African sleeping sickness?

It is technically called human African trypanosomiasis and is a widespread tropical disease transmitted by the infected tsetse fly. Individuals at risk are those who live in the rural areas of East, West and Central Africa or those who travel there.

How can we rid the world of leprosy?

There needs to be awareness programs aimed at the developing countries where leprosy is still an active tropical disease. The stigma attached to leprosy needs to be removed so individuals who have it can seek medical help. There needs to be adequate healthcare and drugs available to those who need it.

Should children be vaccinated against yellow fever?

Yes, the best way to prevent yellow fever is for those individuals who live in areas where yellow fever is active to be vaccinated against it. Individuals who are traveling to those areas should also receive the vaccination. The yellow fever 17 D vaccine is safe and is very effective if administered more than a week before exposure.

Is guinea worm caused by an actual worm?

The tropical disease guinea worm is indeed an actual worm. It is a large roundworm that can be ingested by drinking contaminated water. The disease is normally manifested by a painful blister on the leg.

Which mosquito transmits malaria?

Malaria is transmitted by the female anopheles mosquito. The disease is caused by a one-celled parasite (plasmodium) that they mosquito has picked up from infected people when they bite them.

What can I do to protect myself from tropical diseases?

Only drink bottled water while traveling internationally. Eat only well cooked food and skin any fruit you might eat. Never eat food that has been left out. Use quality sleeping nets and insect repellant. Do not go outside between dusk and dawn. Call your doctor for an appointment at least 6 weeks before leaving for a foreign country to receive any protection from tropical diseases in the area, that are available like antimalaria medicine, other preventatives like vaccinations.

How To Prevent The Spread Of Tropical Diseases

Monday, February 4th, 2008

Whether traveling to the tropics for business or pleasure, you should be aware of possible dangers including tropical diseases. The following are recommendations to follow in order to avoid contracting a tropical disease.

Be sure to bring this list of recommendations to your doctor when you make your 6-week prior to leaving appointment. Your doctor can go over them and let you know which diseases are active in the area you will be traveling to.

The first step to take is to identify the tropical diseases in the area you will be traveling to. As an example – Yellow fever is a tropical disease found in tropical America south of Panama Canal and sub-Saharan Africa. Currently 11 countries in Latin America and 33 countries in Africa have active cases of yellow fever. Most of the cases of yellow fever occur in sub-Saharan Africa.

Receiving available immunizations is a preventative measure that your doctor can explain to you as well as give to you.

You will need to keep your International Certificate of Vaccination (ICV) in your passport to prove that you have been vaccinated. The vaccine should be administered no later than 10 days before entering an active country for that disease.

Malaria is one of the most common of the tropical diseases and can be contracted in both the rural areas as well as the cities.

Malaria is a highly curable disease if caught early on so detection, diagnosis and early treatment are important.

Here are some tips a traveler needs to follow to avoid malaria:

1. First, take the anti-malarial medication when you are in a risk-free zone

2. Avoid bites by using deet containing insect repellent

3. Wear long-sleeved clothing

4. Do not wear perfumes or colognes

5. Sleep inside in an air-conditioned room or if this is not possible sleep under a good quality mosquito net.

The World Health Organization (WHO) has a policy that states that immunization against Cholera is no longer required for travelers.

Tips for traveling safely in tropical diseased areas:

1. Take antimalarial pills

2. Avoid mosquito bites

3. Use sunblock when traveling to tropical climates to avoid burns as damaged skin can be entry points for disease causing agents.

4. Avoid ice, salads and reheated foods, uncooked shellfish and street vendor food should also be avoided as well as any food that has been left out unattended.

5. If you are traveling to the Caribbean, South America, Africa or the Middle East or
 even Southeast Asia then do not swim in fresh water unless you know for sure it is free of biharzia (schistosomiasis)

6. Avoid walking around in bare feet as parasites can be contracted that way. This is actually good advice for any worldwide location not just the tropics.

7. Use condoms when having sex with foreigners and avoid anal-oral sex as this can expose you to diseases including tropical ones.

8. Use either air-conditioning when sleeping or a good quality sleeping net for protection from mosquitoes. It is also wise to spray all window screens with insect repellent.

Use these recommendations and any advice from your doctor and you should be able to prevent any tropical diseases from spoiling your trip.
