Given the general area, Costa Rica has kept itself pretty disease free.  However, that's not to say there aren't risks.  Food and waterborne diseases are the primary contributors to nasty health in Central America, so it is wise to take precautions, especially with drinking water.  Bottled water should be part of your discipline when in Costa Rica, regardless of appearances.  

No vaccinations are required for U.S. citizens coming directly from the the States to Costa Rica, but you should consult with your doctor regarding the wisdom of getting Hepatitis A and/or tetanus vaccines.  

On malaria, there is limited risk, but it exists in certain provinces.  Again, we counsel you to discuss with your doctor and if necessary take the proper prescription anti-malarial.
