Malaria The Neem tree has long been the overstood prevention of malaria. It acts a disinfectant for the liver, where malaria develops. In the presence of the Neem, malaria is not given the opportunity to develop and is ultimately broken down. The Neem is the most common tree in Ghana and a branch with some leaves is readily available to boil as tea. It is suggested that it is taken once a week, as excess can weaken the liver.
Doctors will say that there is no
vaccination for the disease, but actually there does exist a homeopathic
vaccination. Newton Labs has
tincture that should be taken at least one month before your trip.
If you should get the disease, there is
a Chinese herb called artesunate, also readily available at most pharmacists in
Ghana. Clinical Approach:
Preventing Malaria in Travelers
A
guide for travelers to malarious areas Many
people acquire malaria, a potentially life-threatening disease, during travel to
tropical and subtropical countries. Malaria occurs in most of sub-Saharan
Africa, southern and southeast Asia, Mexico, Haiti, the Dominican Republic,
Central and South America, Papua New Guinea, Vanuatu, and the Solomon Islands.
Major cities in Asia and South America are nearly malaria free; cities in
Africa, India, and Pakistan are not. There is generally less risk of malaria at
altitudes above 1500 meters (4500 feet). Malaria and
its symptoms
Malaria is a serious disease that occurs
when an infected Anopheles mosquito bites a person and injects malaria parasites
into the blood. Although four species of malaria parasites can infect humans and
cause illness (Plasmodium falciparum, P.
malariae, P. vivax, and P. ovale), only falciparum malaria is potentially
life threatening.
Symptoms of malaria are flu-like and may
include fever, chills, muscle aches, headache, and, sometimes, vomiting,
diarrhea, and coughing. Patients with severe falciparum malaria may develop
liver and kidney failure, convulsions, and coma. Although infections with P. vivax and P. ovale may
cause less serious illness, parasites may remain dormant in the liver for many
months, causing a reappearance of symptoms months or even years later.
At first, symptoms may be mild. Malaria
should be suspected if the traveler has fever or any of the above symptoms
between 1 week after the first possible exposure to infected mosquitoes and
several months after the last exposure. The period between mosquito bite and
onset of illness is usually 7 to 21 days, but this interval may be longer when
the traveler has taken incomplete or inadequate malaria prevention measures.
If malaria is suspected, medical help
must be sought immediately. A blood sample should be taken to check for malaria
parasites.
About 2% of patients infected with
falciparum malaria die, usually because of delayed treatment. Immediate
treatment of falciparum malaria is critical. Protection
against malaria
No vaccine against malaria is available,
but travelers can protect themselves by using anti-mosquito measures and by
taking drugs to prevent malaria.
Avoiding mosquito bites
Avoiding the bites of Anopheles
mosquitoes (which usually bite only between dusk and dawn) is the best way to
prevent infection.
To avoid mosquito bites
·
Apply insect repellent to exposed skin.
The recommended repellent contains 20%-35% DEET (N,N-diethyl-m-toluamide).
·
Wear long-sleeved clothing and long
pants if you are outdoors at night.
·
Use a mosquito net over the bed if your
bedroom is not air-conditioned or screened. For additional protection, treat the
mosquito net with the insecticide permethrin.
·
Spray an insecticide or repellent on
clothing, as mosquitoes may bite through thin clothing.
·
Spray pyrethrin or a similar insecticide
in your bedroom before going to bed.
Note: Vitamin B and ultrasound devices
do not prevent mosquito bites. Using
antimalarial drugs
Travelers to areas where malaria occurs
should discuss their travel plans with a physician well before departure. Drugs
to prevent malaria are usually prescribed for travelers to malarious areas.
Travelers from different countries may receive different recommendations,
reflecting differences in approach and availability of medicines in different
countries. Travelers visiting only cities or rural areas where there is no risk
of malaria may not require preventive drugs; an exact itinerary is necessary to
decide the degree of protection required.
Drugs recommended for prevention of
malaria in travelers
Mefloquine,
doxycycline, chloroquine
Strict adherence to the recommended
doses and schedules of the antimalarial drug selected is necessary for effective
protection.
·
Take tablets on the same day each week
or, in the case of tablets to be taken daily, at the same time each day.
·
Take tablets after meals.
·
Take the recommended doses 1 to 2 weeks
before travel, throughout the trip, and for 4 weeks after leaving the malarious
area.
·
Don't stop taking the tablets after
arriving home; it is essential to complete the full dosage.
Drug resistance
Choosing antimalarial drugs has become
complicated by the appearance of drug-resistant strains of malaria. In Mexico,
Central America, Haiti, the Dominican Republic, and the Middle East, the
preventive drug of choice is weekly chloroquine. In all other areas of the
malarious world the drug of choice is weekly mefloquine (Lariam*). If mefloquine
cannot be taken, an effective alternative is daily doxycycline. If neither
mefloquine nor doxycycline can be taken, chloroquine (with or without proguanil,
a drug not available in the United States) is a third alternative, but this drug
is much less effective in most areas. If chloroquine is used in drug-resistant
areas, a suitable stand-by treatment (see Self-treatment ) should be carried in
case malarial symptoms occur and medical help cannot be obtained within 24
hours.
Side effects of antimalarial drugs
All medicines have some side effects;
however, if a serious side effect occurs, the traveler should seek medical help
and discontinue taking the antimalarial drug. Mild nausea, occasional vomiting,
or loose stools are not adequate reasons for stopping the antimalarial drug. The
seriousness of malaria warrants tolerating temporary side effects.
Self-treatment
The antimalarial drug
sulphadoxine-pyrimethamine (Fansidar*) can be carried for self-administration
when fever and flu-like symptoms occur during travel and prompt medical
attention is not available. This is a temporary measure only, and medical advice
should be sought as quickly as possible. Travelers who become ill after their
return home should never treat their illness themselves. Instead, they should
seek prompt medical attention and inform their doctor of recent travel. Prevent
malaria
During travel to areas in which malaria
is present,
·
Use anti-mosquito measures
·
Take a drug to prevent malaria
·
Consult a physician if you get sick
·
