RIG was often or always accessible for 100% (n = 5) of respondents in the Middle East and North Africa; 94% (n = 17) in Australia and South and West Pacific Islands; 20% (n = 1) in Tropical South America; and 56% (n = 5) in Eastern Europe and Northern Asia. Ninety-one percent (n = 158) of all respondents reported that RV was often or always see more accessible. For all regions, 35% (n = 58) and 26% (n = 43) of respondents felt that the cost was too high for RIG and RV, respectively. The availability of RV and RIG varied by geographic region. All travelers should be informed that RIG and RV might not be

readily available at their destination and that travel health and medical evacuation insurance should be considered prior to departure. Travelers should be educated to avoid animal exposures; to clean all animal bites, licks, and scratches thoroughly with soap and water; and to seek medical care immediately, even if overseas. Rabies is an acute, progressive, Natural Product Library nearly universally fatal encephalomyelitis caused by neurotropic viruses (family Rhabdoviridae, genus Lyssavirus); transmission usually occurs through the bite from a rabid mammal. While rabies has one of the highest case-fatality ratios of any infectious disease, it is highly preventable

with appropriate postexposure prophylaxis (PEP), which includes thorough wound washing and timely infiltration with rabies immune globulin (RIG) and administration of a series of rabies vaccine (RV) doses. An accurate rate of possible rabies exposures in travelers has not been calculated, although a recent study estimated from PEP records that 0.4% (range 0.01%–2.3%) of travelers receive an at-risk bite per month residence in a rabies-endemic country.[1] Canine rabies-endemic countries (ie, Africa, Asia, and parts of the Americas)

Cediranib (AZD2171) remain the highest risk to most travelers.[2] Health care providers advising travelers pre-travel to rabies-endemic areas might recommend rabies preexposure vaccination for certain travelers engaging in activities that may increase contact with wildlife (particularly bats) or staying in country for extended periods of time. However, even in industrialized countries, periodic supply limitations of RV can influence prioritization for preexposure vaccination. During periods of limited RV supply in the United States (eg, during 2008–2009), travelers who want or need preexposure vaccination may be assigned lower priority to ensure adequate vaccine for PEP and persons with high-risk occupational exposures (ie, rabies diagnostic laboratory workers).[3] Currently, only human RIG (HRIG) products are licensed in the United States. While HRIG is the preferred product for PEP, it is expensive and typically in chronic limited supply, especially in nonindustrialized countries with the highest rabies burden. Equine RIG (ERIG) is used worldwide and is available in both purified and unpurified forms.
