Health
All travelers should visit either their personal physician or a travel health clinic 4-8 weeks before traveling to Sri Lanka. Make sure your health insurance covers you for medical expenses abroad.
General Advice
Bring adequate supplies of all medications in their original containers, clearly labeled. Carry a signed, dated letter from the primary physician describing all medical conditions and listing all medications, including generic names. If carrying syringes or needles, be sure to carry a physician’s letter documenting their medical necessity. If you wear glasses or contacts, bring an extra pair. If you have significant allergies or chronic medical problems, wear a medical alert bracelet.
Avoid contact with stray dogs and other animals. If an animal bites or scratches you, clean the wound with large amounts of soap and water and contact local health authorities immediately. Wear sun block regularly when needed. Use condoms for all sexual encounters. Ride only in motor vehicles with seat belts. Do not ride on motorcycles.
Food and Water Precautions
Do not drink tap water unless it has been boiled, filtered, or chemically disinfected. Do not drink unbottled beverages or drinks with ice. Do not eat fruits or vegetables unless they have been peeled or cooked. Avoid cooked foods that are no longer piping hot. Cooked foods that have been left at room temperature are particularly hazardous. Avoid unpasteurized milk and any products that might have been made from unpasteurized milk, such as ice cream. Avoid food and beverages obtained from street vendors. Do not eat raw or undercooked meat or fish. Some types of fish may contain poisonous biotoxins even when cooked. Barracuda in particular should never be eaten. Other fish that may contain toxins include red snapper, grouper, amberjack, and sea bass.
All travelers should bring along an antibiotic and an antidiarrheal drug to be started promptly if significant diarrhea occurs, defined as three or more loose stools in an 8-hour period or five or more loose stools in a 24-hour period, especially if accompanied by nausea, vomiting, cramps, fever or blood in the stool. Antibiotics which have been shown to be effective include ciprofloxacin (Cipro), levofloxacin (Levaquin), rifaximin (Xifaxan), or azithromycin (Zithromax). Either loperamide (Imodium) or diphenoxylate (Lomotil) should be taken in addition to the antibiotic to reduce diarrhea and prevent dehydration.
If diarrhea is severe or bloody, or if fever occurs with shaking chills, or if abdominal pain becomes marked, or if diarrhea persists for more than 72 hours, medical attention should be sought.
Malaria
Prophylaxis is recommended year-round for all areas, except for the districts of Colombo, Galle, Kalutara, and Nuwara Eliya. Either mefloquine (Lariam), atovaquone/proguanil (Malarone)(PDF), or doxycycline may be given. Mefloquine is taken once weekly in a dosage of 250 mg, starting one-to-two weeks before arrival and continuing through the trip and for four weeks after departure. Mefloquine may cause mild neuropsychiatric symptoms, including nausea, vomiting, dizziness, insomnia, and nightmares. Rarely, severe reactions occur, including depression, anxiety, psychosis, hallucinations, and seizures. Mefloquine should not be given to anyone with a history of seizures, psychiatric illness, cardiac conduction disorders, or allergy to quinine or quinidine. Those taking mefloquine (Lariam) should read the Lariam Medication Guide (PDF). Atovaquone/proguanil (Malarone) is a recently approved combination pill taken once daily with food starting two days before arrival and continuing through the trip and for seven days after departure. Side-effects, which are typically mild, may include abdominal pain, nausea, vomiting, headache, diarrhea, or dizziness. Serious adverse reactions are rare. Doxycycline is effective, but may cause an exaggerated sunburn reaction, which limits its usefulness in the tropics.
Long-term travelers who may not have access to medical care should bring along medications for emergency self-treatment should they develop symptoms suggestive of malaria, such as fever, chills, headaches, and muscle aches, and cannot obtain medical care within 24 hours. See malaria for details. Symptoms of malaria sometimes do not occur for months or even years after exposure.
Insect and Tick Protection
Wear long sleeves, long pants, hats and shoes (rather than sandals). For rural and forested areas, boots are preferable, with pants tucked in, to prevent tick bites. Apply insect repellents containing 25-50% DEET (N,N-diethyl-3-methylbenzamide) or 20% picaridin (Bayrepel) to exposed skin (but not to the eyes, mouth, or open wounds). DEET may also be applied to clothing. Products with a lower concentration of either repellent need to be repplied more frequently. Products with a higher concentration of DEET carry an increased risk of neurologic toxicity, especially in children, without any additional benefit. Do not use either DEET or picaridin on children less than two years of age. For additional protection, apply permethrin-containing compounds to clothing, shoes, and bed nets. Permethrin-treated clothing appears to have little toxicity. Don’t sleep with the window open unless there is a screen. If sleeping outdoors or in an accomodation that allows entry of mosquitoes, use a bed net, preferably impregnated with insect repellent, with edges tucked in under the mattress. The mesh size should be less than 1.5 mm. If the sleeping area is not otherwise protected, use a mosquito coil, which fills the room with insecticide through the night. In rural or forested areas, perform a thorough tick check at the end of each day with the assistance of a friend or a full-length mirror. Ticks should be removed with tweezers, grasping the tick by the head. Many tick-borne illnesses can be prevented by prompt tick removal.
The following are the recommended vaccinations for Sri Lanka:
| Vaccine | Recommendations |
| Hepatitis A | Recommended for all travelers |
| Typhoid | Recommended for all travelers |
| Polio | One-time booster recommended for any adult traveler who completed the childhood series but never had polio vaccine as an adult. |
| Yellow fever | Required for all travelers greater than one year of age arriving from a yellow-fever-infected area in Africa or the Americas. Not recommended otherwise. |
| Japanese encephalitis | For long-term (>1 month) travelers to rural areas or travelers who may engage in extensive unprotected outdoor activities in rural areas, especially after dusk. |
| Hepatitis B | For travelers who may have intimate contact with local residents, especially if visiting for more than 6 months. |
| Rabies | For travelers who may have direct contact with animals and may not have access to medical care. |
| Measles, mumps, rubella (MMR) | Two doses recommended for all travelers born after 1956, if not previously given. |
| Tetanus-diphtheria | Revaccination recommended every 10 years. |
| Cholera | Recommended for tsunami relief workers. |
Hepatitis A vaccine is recommended for all travelers over one year of age. It should be given at least two weeks (preferably four weeks or more) before departure. A booster should be given 6-12 months later to confer long-term immunity. Two vaccines are currently available in the United States: VAQTA (Merck and Co., Inc.) (PDF) and Havrix (GlaxoSmithKline) (PDF). Both are well-tolerated. Side-effects, which are generally mild, may include soreness at the injection site, headache, and malaise.
Older adults, immunocompromised persons, and those with chronic liver disease or other chronic medical conditions who have less than two weeks before departure should receive a single intramuscular dose of immune globulin (0.02 mL/kg) at a separate anatomic injection site in addition to the initial dose of vaccine. Travelers who are less than one year of age or allergic to a vaccine component should receive a single intramuscular dose of immune globulin (see hepatitis A for dosage) in the place of vaccine.
Typhoid vaccine is recommended for all travelers. It is generally given in an oral form (Vivotif Berna) consisting of four capsules taken on alternate days until completed. The capsules should be kept refrigerated and taken with cool liquid. Side-effects are uncommon and may include abdominal discomfort, nausea, rash or hives. The alternative is an injectable polysaccharide vaccine (Typhim Vi; Aventis Pasteur Inc.) (PDF), given as a single dose. Adverse reactions, which are uncommon, may include discomfort at the injection site, fever and headache. The oral vaccine is approved for travelers at least six years old, whereas the injectable vaccine is approved for those over age two. There are no data concerning the safety of typhoid vaccine during pregnancy. The injectable vaccine (Typhim Vi) is probably preferable to the oral vaccine in pregnant and immunocompromised travelers.
Polio vaccine is not generally recommended for adult travelers who completed the recommended childhood immunizations, since polio has not been reported from Sri Lanka for several years. A one-time booster of inactivated polio vaccine may be considered for extended travel to rural areas.
Yellow fever vaccine is required for all travelers over one year of age arriving from a yellow-fever-infected country in Africa or the Americas, but is not recommended or required otherwise. Yellow fever vaccine (YF-VAX; Aventis Pasteur Inc.) (PDF) must be administered at an approved yellow fever vaccination center, which will give each vaccinee a fully validated International Certificate of Vaccination. Yellow fever vaccine should not in general be given to those younger than nine months of age, pregnant, immunocompromised, or allergic to eggs.
Japanese encephalitis vaccine is recommended for long-term (1 month) travelers to rural areas or travelers who may engage in extensive unprotected outdoor activities in rural areas, especially in the evening, during shorter trips. The disease occurs throughout the country, except for mountainous areas. Outbreaks have been reported recently from central (Anuradhapura) and northwestern provinces. Transmission occurs from October to January and May to June. For a map of Japanese encephalitis cases in Sri Lanka, go to the World Health Organization — South-East Asia Region.
The vaccine (JE-VAX; Aventis Pasteur Inc.) is given as a series of three injections on days 0, 7 and 30. If time is short, the third dose may be given on day 14. Mild side effects including fever, headache, muscle aches, malaise and soreness at the injection site occur in about 20% of those vaccinated. Serious allergic reactions including urticaria, angioedema, respiratory distress and anaphylaxis occur in approximately 0.6% of vaccinees and may occur as long as one week after vaccination. Any person who receives the vaccine should be observed in the doctor’s office for at least 30 minutes following the injection and should complete the full series at least 10 days before departure. There are no data concerning the safety of Japanese encephalitis vaccine during pregnancy.
Hepatitis B vaccine is recommended for travelers who will have intimate contact with local residents or potentially need blood transfusions or injections while abroad, especially if visiting for more than six months. It is also recommended for all health care personnel. Two vaccines are currently licensed in the United States: Recombivax HB (Merck and Co., Inc.) (PDF) and Engerix-B (GlaxoSmithKline) (PDF). A full series consists of three intramuscular doses given at 0, 1 and 6 months. Engerix-B is also approved for administration at 0, 1, 2, and 12 months, which may be appropriate for travelers departing in less than 6 months. Side-effects are generally mild and may include discomfort at the injection site and low-grade fever. Severe allergic reactions (anaphylaxis) occur rarely.
Rabies vaccine is recommended only for those at high risk for animal bites, such as veterinarians and animal handlers, and for long-term travelers who may have contact with animals and may not have access to medical care. In Sri Lanka, most cases of rabies are caused by dog bites. (For further information, go to Emerging Infectious Diseases.) A complete preexposure series consists of three doses of vaccine injected into the deltoid muscle on days 0, 7, and 21 or 28. Side-effects may include pain at the injection site, headache, nausea, abdominal pain, muscle aches, dizziness, or allergic reactions.
Any animal bite or scratch should be thoroughly cleaned with large amounts of soap and water and local health authorities should be contacted immediately for possible post-exposure treatment, whether or not the person has been immunized against rabies.
Measles-mumps-rubella vaccine: two doses are recommended (if not previously given) for all travelers born after 1956, unless blood tests show immunity. Many adults born after 1956 and before 1970 received only one vaccination against measles, mumps, and rubella as children and should be given a second dose before travel. MMR vaccine should not be given to pregnant or severely immunocompromised individuals.
Tetanus-diphtheria vaccine is recommended for all travelers who have not received a tetanus-diphtheria immunization within the last 10 years.
Cholera vaccine is not generally recommended, except for relief workers in tsunami-affected areas, because most travelers are at low risk for infection. Two oral vaccines have recently been developed: Orochol (Mutacol), licensed in Canada and Australia, and Dukoral, licensed in Canada, Australia, and the European Union. These vaccines, where available, are recommended only for high-risk individuals, such as relief workers, health professionals, and those traveling to remote areas where cholera epidemics are occurring and there is limited access to medical care. The only cholera vaccine approved for use in the United States is no longer manufactured or sold, due to low efficacy and frequent side-effects.
