MILWAUKEE — As the Centers for Disease Control and Prevention, doctors and scientists worldwide continue to study the impact and effects of COVID-19, most admit there's still a lot to learn about the virus and complications tied to it.

"Other post-viral syndromes do exist and we don't necessarily know a lot about those either," Dr. Matt Anderson, UW Health's senior medical director of primary care, told Spectrum News 1. "A lot of it is supportive treatment management. Why it occurs? How specifically [can] we best address it in a way that offers more immediate relief? It's something we're still needing to get more information about going forward."

The CDC continues to change its recommended approach for healthcare providers to help "long haulers," defined by the agency as those patients with COVID-19 who've dealth with "post-COVID conditions" for four weeks or longer past their original infection. They recently offered "new diagnostic, treatment and management considerations" for doctors and hospitals nationwide, according to a press release from UW Health.

"Those symptoms can include a wide variety of things: fatigue; cough; shortness of breath; some people are dealing with mental health issues [including] depression, anxiety or brain fog types of symptoms," Dr. Anderson added. "There's a lot more frequency than we see with other viral infections."

Dr. Anderson went on to recommend getting vaccinated against COVID-19 as the best way to prevent contraction of the virus and potentially having to deal with any "post-COVID conditions."
