Hepatitis A: This is a viral infection of the liver and is contracted mainly from contaminated food and water.
The vaccination is strongly recommended, and a booster after 6 or 12 months guarantees protection for over 10 years.
Typhoid fever: This dangerous gut infection is also acquired from food and water.
Yellow fever: This vaccination is necessary when entering Ecuador from Peru and Columbia (both officially infected countries), but it’s a good idea in any case because it’s a dangerous disease.
Hepatitis B: This is a less-common travelers’ disease because it’s contracted through sexual contact or exposure to infected blood.
