Cuba: US Embassy issues health alert due to GI pathogens like norovirus, Shigella

The US Embassy in Havana issued a health alert last week after seeing a significant increase in diarrheal illness across Cuba, associated with the continuing degradation of the water and energy infrastructure.

This degradation affects water supply, and food storage and temperature control. Recent cases have included E. coli, norovirus, Shigella, and other gastrointestinal pathogens.

This comes after a health alert dated August 28 which noted that Cuba’s water delivery infrastructure is increasingly unstable.

The Embassy is aware of reports of residential neighborhoods that have gone for long periods without receiving water from municipal or public sources.

Prolonged and worsening water issues and power outages caused by the regime’s mismanagement of public infrastructure impact the entire island. Water often only flows to residences when city power is on for a sufficient amount of time. Media reports indicate wells are running dry across the country due to drought, aggravating the ability to supplement water delivery.

The lack of water, coupled with power shortages that have disrupted cold chain networks, can present significant health and safety challenges. We remind U.S. citizens to be aware of the risks when traveling to Cuba and take precautions.

Embassy officials offer the following precautions to prevent illnesses:

Avoiding Foodborne Illness:

• Be cautious of meat, poultry, seafood, eggs, dairy, and other perishable foods that may have been inadequately stored.

• Avoid foods that appear to have been sitting at room temperature for extended periods.

• Avoid raw or improperly washed vegetables.

• Be cautious of food cooked and then cooled, stored, or reheated, as improper temperature control can allow pathogens or toxins to develop.

• Wash hands thoroughly with soap and water before eating and after using the restroom. Hand sanitizer may be less effective against certain gastrointestinal pathogens, including norovirus.

Water Safety:

• Use only water known to be safe for drinking, brushing teeth, making ice, and cooking.

• Use bottled or appropriately treated water; check that bottle seals are intact before opening.

• Avoid ice unless the water source is known to be safe.

• Do not use untreated tap water to prepare beverages or food.

• Be aware that contamination can occur when food, utensils, and surfaces are washed with contaminated water.

If You Become Ill:

• Stay hydrated, especially with frequent diarrhea or vomiting. Most illnesses are self-limited and improve within several days.

• Seek medical attention for persistent or severe diarrhea, bloody stools, high fever, significant abdominal pain, repeated vomiting, signs of dehydration, or symptoms not improving.

• Common medications (e.g., acetaminophen, ibuprofen, antibiotics) are frequently unavailable in Cuba; consider bringing your own supply.
