CDC WARNING LEVEL 3
Avoid Nonessential Travel to the Northern Mariana Islands, Central Sulawesi, Indonesia and Venezuela
On October 25, 2018, Super Typhoon Yutu crossed the Commonwealth of the Northern Mariana Islands causing significant damage. There are problems with water supply, sanitation, food supply, electricity, transportation, shelter, communications, security, medical care and mosquito control. In addition to safety hazards caused by debris and unstable buildings, there are serious health and safety risks, medical care may not be available and visitors could further strain local resources. CDC recommends that U.S. residents avoid all nonessential travel to the Northern Mariana Islands. If travel to the area is necessary, follow CDC recommendations for health and
Two recent natural disasters have caused severe damage, injuries and deaths in the province of Central Sulawesi, Indonesia. On September 28, 2018, earthquakes struck the Donggala region and triggered a tsunami wave that hit the Donggala and Mamuju regions and the city of Palu. In addition to safety hazards caused by debris and unstable buildings, there may be problems with sanitation, food supply, electricity, transportation, shelter, communications, security and medical care. There are serious health and safety risks, medical care may not be available and visitors could further strain limited local resources. CDC recommends that travelers avoid all nonessential travel. If travelers must go to the area or are doing humanitarian aid
work, follow CDC health advice before, during and after the trip. For more information, visit the Department of State Travel Advisory for Indonesia.
There has been a breakdown of the medical infrastructure in Venezuela. There are shortages of food, water, electricity, medicine and medical supplies that have contributed to an increasing humanitarian crisis affecting much of the country. Adequate health care is not available through the public health system. For this reason, in addition to crime and civil unrest, the U.S. government has limited ability to provide emergency services to U.S. citizens. Infectious diseases are on the rise, and several large outbreaks are occurring including measles, diphtheria and malaria. CDC recommends that
travelers avoid all nonessential travel to Venezuela. Travelers that must go to Venezuela should protect themselves by following CDC recommendations. For more information, visit the Department of State Travel Advisory for Venezuela.
Updates, Outbreaks & Security Concerns

Travelers should protect themselves by frequently washing hands with soap and water and by avoiding contact with animals and humans that are sick.
- There is an outbreak of Ebola in North Kivu (Kivu Nord) and Ituri provinces of the Democratic Republic of the Congo including the cities of Beni and Butembo. Travelers should take precautions to avoid contact with the blood and bodily fluids of infected individuals. The risk to most travelers is low. Those at highest risk of acquiring Ebola are healthcare workers and family and friends caring for the sick. This part of the country is 780 miles from the most recent outbreak and is identified as a "do not travel" zone by the U.S. State Department because of armed group activity and major outbreaks of violence targeting civilians.
- There are currently outbreaks of polio in Niger, Somalia, Nigeria and the Democratic Republic of the Congo. The CDC recommends that all travelers to these countries be vaccinated against
polio. Additionally, adults who have been fully vaccinated should receive a single lifetime booster dose of polio vaccine before travel. Travelers that will be in any of these countries greater than 4 weeks may be required to show proof of polio vaccination. Because of the risk of cross-border transmission, CDC recommends a one-time booster dose of polio vaccine for fully vaccinated adults traveling to Niger, Cameroon or Chad to work in healthcare facilities, refugee camps or other humanitarian settings.
- There is an outbreak of Rift Valley Fever (RVF) in Kenya. The outbreak has been confirmed in the countries of Wajir, Marsabit and Siaya. Travelers should avoid exposure to animals, animal blood and mosquito bites.

Those never vaccinated against yellow fever should avoid travel to Nigeria during the outbreak. Nigerian authorities require proof of yellow fever vaccination from all people one year of age or older traveling to Nigeria from a country with risk of yellow fever virus transmission. Because of current limitations in the availability of yellow fever vaccine
in the United States, travelers should contact a yellow fever vaccine provider well in advance of travel.
