Travelers Disease Information
Hepatitis A
    Hepatitis A is very common in developing countries where sanitation is poor.
    Travelers can be infected from person-to-person contact or through food and water
    that have been contaminated with animal or human feces. In adults, hepatitis A
    usually results in liver disease, characterized by jaundice -- a yellowing of the skin --
    that can last a month or more. Other symptoms may include fatigue, nausea,
    stomach pains, and general weakness; however, children may show no symptoms
    at all. The disease can be severe and possibly fatal. If traveling to an area where
    hepatitis A is common, your travel health-care professional should ensure that you
    receive the hepatitis A vaccine.


Hepatitis B
    Hepatitis B is one of several viruses that may cause hepatitis (liver disease), and
    may result in a particularly severe form of hepatitis that leads to liver cancer or
    death. It is widespread in many developing countries, especially in Africa, southeast
    Asia, the Middle East (except Israel), south and western Pacific Islands, the interior
    Amazon Basin, and certain parts of the Caribbean. Travelers who will have daily
    physical contact with the local population in areas of the world where hepatitis B is
    prevalent should receive vaccination.
Below, information is provided on selected diseases to increase your
awareness and hopefully minimize the risks to your health while away
from home.

There are risks associated with all vaccines. As with any vaccine,
vaccination may not protect 100% of individuals. Please consult your
physician for full Prescribing Information.

Cholera
    Cholera is a disease characterized by severe diarrhea leading to rapid dehydration which, if untreated, may lead to death
    within 24 hours. Cholera is transmitted through contaminated food or water. Cholera may be present in Asia, the Middle East,
    Africa, parts of Europe, and South and Central America, including Mexico. Cholera vaccine is no longer required nor
    recommended for the vast majority of travelers by the Centers for Disease Control and Prevention (CDC). The vaccination
    consists of 2 injections at least 1 week apart.
Malaria
    Malaria is a parasitic disease transmitted by infected female mosquitoes. Malaria may occur as soon as one (1) week after
    you enter the tropics, and may progress rapidly to cause seizures, coma, breathing and kidney problems, and death. The
    initial symptoms of malaria look much like the common flu -- fever, chills, headache, and generalized aches and pains. You'll
    need a blood test to determine if you have malaria.
Meningoccal Disease
    Meningococcal disease is a significant cause of illness and death worldwide. The
    meningococcal bacteria can cause meningitis (infection of the brain and spinal
    cord) and a variety of other diseases. The bacteria are usually spread from person
    to person via coughing, sneezing, or direct contact. Meningococcal disease can
    strike with frightening quickness. The early symptoms -- fever, headache, and
    general malaise -- are indistinguishable from many less serious illnesses.
    However, the disease can kill an otherwise healthy person within 48 hours, if left
    untreated. Vaccination with meningococcal vaccine is recommended for travelers to
    countries in the meningitis belt of Africa or to the Hajj (an annual Islamic tradition).


Polio
    As shown on the map to the right, polio is a disease that occurs in the developing
    world outside North and South America, and may result in partial or total paralysis.
    Polio is transmitted primarily through food or water contaminated with feces.
    Americans traveling to areas of the world where polio is still prevalent should have
    received their primary immunization series of polio vaccine and a booster within the
    last 10 years. If you have not received the primary series, then you should receive at
    least 2 doses of polio vaccine, 4 to 8 weeks apart, prior to departure, if time allows.
    A third dose should be administered 6 to 12 months after the second.


Typhoid Fever
    Typhoid fever is a life-threatening illness. It's usually spread under unsanitary
    conditions, either person to person, or though contaminated food, drink, or water.
    Typhoid fever is characterized by a high fever (which gradually increases, often to
    over 104 degrees Farenheit, headache, tiredness, loss of appetite, and dizziness.
    Other symptoms include abdominal pain, nausea, chills, and constipation or
    diarrhea. This disease is common in many developing countries of the Indian
    subcontinent, Africa, Asia, the Caribbean, and Central and South America.
    Vaccination is recommended for all travelers to risk areas.


Yellow Fever
    Yellow fever is a viral illness. The disease is carried by some species of
    mosquitoes in Central and South America, and sub-Saharan Africa. A mild attack
    may have symptoms similar to those of influenza. However, more severe symptoms
    may include nausea, vomiting, bleeding, abdominal pains, and yellowing of the skin
    as a result of liver damage. Travelers to endemic areas, or those transiting through
    a disease area and entering another country, may require a certificate of vaccination
    against yellow fever for legal entry. Your vaccination will consist of a single injection,
    and can be administered only at a clinic licensed to administer yellow fever vaccine.
    Your certificate is valid for 10 years, beginning 10 days after you receive your
    vaccination..
