Health officials in the middle American state of Nebraska say they are not planning to give regular updates about a US aide worker who could have been exposed to the often-deadly Ebola virus.

The unidentified American health care professional was providing medical assistance in the Democratic Republic of the Congo, and transferred to Nebraska Health which treated three health care workers exposed to Ebola during the 2014 West African epidemic.  Unless the new patient starts to exhibit symptoms of infection, the next news update will come after the two week monitoring period.

Dr. Ted Cieslak, an infectious diseases specialist with Nebraska Medicine and associate professor of epidemiology in the University of Nebraska Medical Center College of Public Health said, "Should any symptoms develop, the Nebraska Medicine/UNMC team is among the most qualified in the world to deal with them."

The Ebola outbreak in the DR Congo is the second most-deadly since the virus was discovered in the country during the 1970s.  It's also the second outbreak in the country since the beginning of the year.  DR Congo's health ministry says there have been at least 593 confirmed or suspected infections and at least 360 fatalities.

This is happening in an active war zone.  The United Nations World Health Organization says efforts to treat patients or immunize people with experimental vaccines are greatly hampered by fighting between the government and armed militias.  Protests over the government's decision to delay voting in the presidential election are also stifling the Ebola fight.
