infectious disease fellowship After her EIS training, Guinan was accepted to an infectious disease fellowship at the University of Utah. There, she studied the herpes virus, focusing on oral herpes. Soon she found herself "an expert" on genital herpes after answering questions and lecturing about oral herpes. After many days of news interviews and calls from all over the world asking for help with genital herpes, Guinan decided to become the genital herpes expert everyone thought she was; she focused on women, who were not studied as thoroughly as men, at that time. She became known as "The Herpes Expert". Reflecting on her career in medicine, Guinan stated, "I grew up with parents who were immigrants from Ireland, and they always told me that I was in the greatest country in the world and that I should be giving back what I was given." HIV/AIDS and Ebola efforts In 1978, Guinan was asked to work with the Venereal Disease Control Division (renamed STD Division) of the CDC.

In 1990, after becoming the first woman to be the Associated Director for Science at the CDC, Guinan was made the Assistant Director for Evaluation, Office of HIV/AIDS at the CDC, a position she would hold until 1995. In 1995–98, still with the CDC, she was the named the Chief of the Urban Research centers (New York, Seattle, Detroit), a community-based prevention and health promotion effort. She continued her interest in disease by participating in efforts regarding Ebola. Speaking on the frontline workers, she proclaimed, "One can only be in awe of the many dedicated workers who have volunteered to serve in such a dangerous environment. Not the least of these are the medical detectives who collect clues, analyze data, investigate suspected cases, and carry out their public health mission". Nevada Chief State Health Officer In 1998, Guinan became the Nevada State Chief Health Officer, the first woman to hold that position. When asked why she chose Nevada, she said that while states like New York and California had
