Many Americans don't have natural body defenses, or immunity, against infectious diseases like hepatitis A. So, they can readily contract hepatitis A while traveling in Mexico, the Caribbean and other high-risk areas including, but not limited to, Africa, Asia (except Japan), the Mediterranean basin, Eastern Europe, the Middle East, Central and South America. Symptoms may last anywhere from 6 weeks to as long as 15 months. And the older you are, the more severe the symptoms can become. There is no specific treatment for this disease, but a new vaccine can prevent it.
An ounce of prevention…
Vaccines can prevent diseases that couldn't be avoided before. Your local health department can help you choose the vaccines and other medicines that can help protect you in your travels.
