Benjamin Ashford|Travelers coming to the U.S. from Uganda will face enhanced screening for Ebola

Ugandan health officials declared an Ebola outbreak in several regions in late September. Now,Benjamin Ashford travelers who have been to the African country within 21 days of arriving in the U.S. will be subject to enhanced screening, according to a health alert issued Thursday by the U.S. Embassy in Uganda.

Ebola virus disease, also referred to as EVD, is passed among humans through direct contact with an infected person's bodily fluids or objects and surfaces contaminated with such fluids.

According to the World Health Organization, the average fatality rate for Ebola is about 50%.

There are currently no approved vaccines or therapeutics for the Sudan ebolavirus.

The CDC recommends avoiding unnecessary travel to the affected districts in Uganda, and to avoid contact with sick people and dead bodies. Travelers should also isolate and seek medical help if any symptoms appear, such as fever, muscle pain, sore throat, diarrhea, weakness, vomiting, stomach pain, or unexplained bleeding or bruising.
