Airborne & Droplet
Counsel your patients on actions they can take on their trip to stay healthy and safe.
Counsel travelers to be diligent about food and water precautions:
- Avoid cooked food served at room temperature.
- Avoid raw food, including raw vegetables unless they can be washed thoroughly.
- Drink only beverages from sealed bottles or cans.
- Water is safe if it has been boiled or chemically treated.
- Avoid ice unless made from bottled/disinfected water.
Consider prescribing an antibiotic for self-treatment of travelers’ diarrhea, factoring in resistance issues at the destination.
Counsel travelers to be diligent in insect precautions:
- Cover exposed skin.
- Use an appropriate insect repellent. (see below)
- Use permethrin-treated clothing and gear (such as boots, pants, socks, and tents). Travelers can buy pre-treated clothing and gear or treat them at home. Treated clothing remains protective after multiple washings. Permethrin should NOT be used directly on skin.
- Stay and sleep under in air-conditioned or screened rooms.
- Use a bed net if sleeping area is exposed to the outdoors.
More Information on Insect Repellents
DEET (concentration of 20% or more) is the only insect repellent shown to be effective against ticks. However, several EPA-registered active ingredients provide reasonably long-lasting protection against mosquitoes:
- DEET (chemical name: N,N-diethyl-m-toluamide or N,N-diethyl-3-methyl-benzamide): Concentrations above 50% show no additional protective benefit.
- Picaridin (KBR 3023 [Bayrepel] and icaridin outside the United States; chemical name: 2-(2-hydroxyethyl)-1-piperidinecarboxylic acid 1-methylpropyl ester): Must be reapplied more often than DEET.
- Oil of lemon eucalyptus (OLE) or PMD (chemical name: para-menthane-3,8-diol), the synthesized version of OLE. “Pure” oil of lemon eucalyptus (essential oil) is not the same product; it has not undergone similar testing for safety and efficacy, is not registered with EPA as an insect repellent, and is not covered by this recommendation.
- IR3535 (chemical name: 3-[N-butyl-N-acetyl]-aminopropionic acid, ethyl ester).
Products with <10% active ingredient may offer only limited protection (1–2 hours).
Encourage patients to use repellents and reapply only as instructed. If sunscreen is also needed, they should apply sunscreen first and repellent second. Encourage them to follow package directions for using repellent on children and avoid applying to their hands, eyes, and mouth.

Advise travelers to exercise caution during outdoor activities. Important tips include dressing appropriately for the climate (such as loose, lightweight clothing in hot climates and warm layers in cold climates), staying hydrated, avoiding overexposure to the sun, and practicing safe swimming habits. To avoid infection while swimming, travelers should not swallow water when swimming and avoid contact with water that may be contaminated from poor sanitation.
Encourage travelers to learn basic first aid and CPR before travel, especially if they will be traveling to remote areas where medical assistance may not be accessible. Help them assemble a travel health kit.
Schistosomiasis is endemic in Senegal. Travelers should avoid swimming in fresh, unchlorinated water, such as lakes, ponds, or rivers.
Health experts urge us to eat more fish because of its beneficial health effects, but toxins in contaminated fish can cause health problems. Two common causes of fish-related food poisoning are ciguatera and scombroid, and travelers may be at risk of these illnesses.
Ciguatera (sig-wah-TARE-ah) is caused by eating fish contaminated with toxins that are produced by microorganisms that live around coral reefs. Small fish eat the microorganisms, and large fish eat the small fish, which concentrates the toxins. The highest concentrations of toxins are found in the liver, intestines, eggs, and head.
Risk to travelers
Because fish can be shipped around the world, ciguatera can occur anywhere, including in the United States. However, the risk is highest in fish from the Caribbean Sea and the Pacific and Indian Oceans. As many as 3% of travelers to these areas get ciguatera. Ciguatera is most commonly caused by eating barracuda, grouper, moray eel, amberjack, sea bass, sturgeon, parrot fish, surgeonfish, and red snapper.
Ciguatera symptoms usually develop 1–3 hours after eating contaminated fish. They can include nausea, vomiting, diarrhea, and stomach pain. Some people may have neurologic symptoms, such as a tingling sensation, tooth pain or feeling as if the teeth are loose, itching, a metallic taste in the mouth, and blurred vision.
There is no treatment for ciguatera, so travelers should avoid eating the fish listed above, particularly barracuda and moray eel, and avoid eating the organs in which the concentration of toxins is highest. The toxins that cause ciguatera do not affect the appearance, taste, or smell of fish, so there is no way to tell if fish is contaminated. The toxins are not destroyed by heat, so even thoroughly cooked fish is a risk.
Scombroid (SKOM-broyd) is caused by eating fish that has not been properly refrigerated or preserved and therefore contains high levels of histamine. Scombroid is most commonly caused by fish that have naturally high levels of the amino acid histidine, which bacteria convert to histamine when the fish is not correctly stored.
Risk to travelers
Scombroid occurs worldwide. Fish typically associated with it include tuna, mackerel, mahimahi, sardines, anchovies, herring, bluefish, amberjack, and marlin.
Scombroid symptoms usually develop within a few minutes to an hour after eating contaminated fish. They usually resemble an allergic reaction, such as flushing of the face, headache, heart palpitations, itching, blurred vision, cramps, and diarrhea. Symptoms can be treated with antihistamines. Even without treatment, people usually get better within 12 hours.
Contaminated fish may taste peppery, sharp, metallic, or bitter, but it may also look and taste normal. Fish should be iced, refrigerated, or frozen immediately after it is caught. Histamine is not destroyed by heat, so even thoroughly cooked fish is a risk.
People who are ill should not travel. Urge travelers to practice hand hygiene and sneeze into a tissue or their sleeve.Hide
Counsel travelers on the risks of diseases associated with the exchange of saliva, blood, vomit, semen, urine, and feces.
- Use a latex condom correctly every time they engage in sex (vaginal, anal, and oral-genital).
- Not inject drugs.
- Limit alcohol consumption.
- Not have tattoos, piercings, or other procedures that use needles (acupuncture) unless the needles are packaged new or sterilized.
- Ensure that medical and dental equipment is sterile or disinfected if seeking care.

Travelers should plan for how to obtain health care during their trip, should the need arise.
Discuss supplemental travel health insurance and medical evacuation insurance, and consider helping the traveler obtain an extra month of prescriptions for any needed medications.
Travelers may think they can find cheaper antimalarial drugs at their destination. To ensure medication quality, urge them to have their prescriptions filled in the United States.Hide
Motor vehicle crashes are the #1 killer of healthy US citizens in foreign countries.
Most recommendations for safe transportation are basic and could be considered common sense. However, travelers often do not think about the importance of being aware and careful when walking, riding, driving, or flying.
In many places cars, buses, large trucks, rickshaws, bikes, pedestrians, and even animals share the same lanes of traffic, increasing the risk for crashes.
Counsel travelers to think about transportation options before they arrive, especially if they will be driving in Senegal.
Medical Evacuation Insurance
If your patient is seriously injured, emergency care may not be available or may not meet US standards. Trauma care centers are uncommon outside urban areas. Encourage patients to purchase medical evacuation insurance.
Some basic reminders to review with your patients:
- Choose safe vehicles and avoid motorbikes when possible.
- Wear a seatbelt or a helmet at all times.
- Do not drive after drinking alcohol or ride with someone who has been drinking.
- Avoid driving at night; street lighting in certain parts of Senegal may be poor.
- If they will be driving, remind them to get any driving permits and insurance they may need. It is recommended to get an International Driving Permit (IDP).
- Avoid using local, unscheduled aircraft, and fly on larger planes (more than 30 seats) when possible.

Travelers should be reminded on how to protect their personal safety during travel, regardless of their destination.
The US Department of State has an extensive website with safety information for international travelers, travel alerts and warnings, and country-specific information. Travelers should be directed to the Department of State resources for information and tips on safe travel.
Stay abreast of current events, particularly those that could pose a safety or health problem for travelers. You can also receive updates on new travel alerts and warnings from the US Department of State by subscribing to their RSS feeds.Hide
Advising Returning Travelers
Although some illnesses may begin during travel, others may occur weeks, months, or even years after return. A history of travel, particularly within the previous 6 months, should be part of the routine medical history for every ill patient. A newly returned, ill international traveler should be preferentially evaluated by a physician versed in travel-related illness.
Here are two professional medical organizations that provide directories of travel clinics throughout the United States:
- American Society of Tropical Medicine and Hygiene (ASTMH)
- International Society of Travel Medicine (ISTM)
Malaria is always a serious disease and may be a deadly illness. Any patient presenting with a fever after traveling in a malaria-risk area during the last year should be evaluated immediately using the appropriate diagnostic tests for malaria. Malaria, especially P. falciparum, requires urgent intervention as clinical deterioration can occur rapidly and unpredictably.
For more information on advising patients after international travel, see Yellow Book Chapter 5: Post-Travel Evaluation.
