Travel immunizations.
Advising travelers on vaccine-preventable illnesses is increasingly becoming the responsibility of primary care physicians. The approach to vaccine recommendations should be based on a thorough assessment of the risks for travel-related diseases, the time available before trip departure, and current knowledge of the epidemiology of vaccine-preventable diseases. Routine childhood vaccinations should be reviewed in all travelers and updated as necessary. Yellow fever vaccination may be required for entry by countries that lie within a yellow fever zone or for travelers coming from an endemic area to prevent introduction of the disease. Immunization against hepatitis B virus should be considered in travelers who expect to have close contact with local populations that have high rates of hepatitis B transmission. Japanese encephalitis vaccine should be offered to travelers who plan prolonged trips to rural areas in southeast Asia or the Indian subcontinent during the transmission season. Typhoid fever immunization is recommended for travelers who may be exposed to potentially contaminated food and drink. Preexposure rabies vaccination should be considered in travelers who plan a prolonged duration of stay in a remote area or who engage in activities that might involve working near animals or that could attract animals. Physicians should be aware of the adverse events and contraindications associated with each travel vaccine.

Fever in the returned traveler.
With the rising popularity of international travel to exotic locations, family physicians are encountering more febrile patients who recently have visited tropical countries. In the majority of cases, the fever is caused by a common illness such as tracheobronchitis, pneumonia, or urinary tract infection. However, fever in returned travelers always should raise suspicion for a severe or potentially life-threatening tropical infection. In addition to the usual medical history, physicians should obtain a careful travel history, a description of accommodations, information about pretravel immunizations or chemoprophylaxis during travel, a sexual history, and a list of exposures and risk factors. The extent and type of lymphadenopathy are important diagnostic clues. Altered mental status with fever is an alarm symptom and requires urgent evaluation and treatment. Malaria must be considered in patients who traveled even briefly within an endemic area. Enteric fever is treated with fluoroquinolones, dengue fever with supportive measures only, leptospirosis with penicillin or doxycycline, and rickettsial infections with doxycycline.

Prevention of malaria in travelers.
Malaria is a major international public health problem, responsible for considerable morbidity and mortality around the world each year. As travel to tropical locations increases, U.S. physicians are being asked more frequently to provide recommendations for malaria prevention. An organized approach to reducing the risk of acquiring this disease is necessary. Physicians must review the itineraries of their patients in detail, paying particularly close attention to travel within malaria-endemic areas and drug-resistant zones. Appropriate chemoprophylaxis must be chosen to reduce the risk of acquiring malaria. It also is important to provide advice on the use of protective measures that reduce the risk of mosquito bites. Finally, travelers should be instructed to seek medical attention immediately if symptoms of the disease develop during or after the trip.

Eosinophilic meningitis.
Eosinophilic meningitis is a rare clinical entity that can be useful in narrowing the differential diagnosis of central nervous system disease. It is defined by the presence of 10 or more eosinophils/microL in the cerebrospinal fluid (CSF) or a CSF eosinophilia of at least 10%. The most common cause is invasion of the central nervous system by helminthic parasites, particularly Angiostrongylus cantonensis, but other infections as well as noninfectious conditions may also be associated. This review describes the etiologies of eosinophilic meningitis, focusing primarily on the helminths that cause CSF eosinophilia.
