Former Kansas State basketball coach Frank Martin shared a scary revelation with the world on Tuesday.


He tested positive for coronavirus early last month.


In a personal message posted on South Carolina's athletic website, Martin shared some enlightening details about his diagnosis of COVID-19 and his full recovery from the illness. He said he took a coronavirus test on May 8 in preparation for a knee replacement surgery and was shocked to discover that the results came back positive.


"I didn't have any symptoms, other than feeling a bit fatigued, and I immediately entered quarantine at my home," Martin said in his message. "I'm thankful to say that I did not have to be hospitalized."


Martin said his biggest concern was his family, who he has been with every singly day since the college basketball season ended in March. He wondered if he infected them and if they would develop symptoms or need to visit a hospital. Fortunately, after several weeks in quarantine, both he and every member of his family have tested negative for the coronavirus.


"The anxiety, guilt and general angst I experienced after testing positive was overwhelming," Martin wrote. "Thanks to God's will, a week later my family all tested negative and I'm thankful to tell you that on May 23 my follow-up test results came back negative."


Martin began his head-coaching career at Kansas State in 2007 and won 117 games during five seasons with the Wildcats. His best season came in 2009-10, when he guided K-State to 29 victories and a trip to the Elite Eight. Martin was a crowd favorite in Manhattan until he left for South Carolina in 2012 because of a rift with former K-State athletic director John Currie.


With the Gamecocks, Martin has won 147 games over eight seasons. His best season at South Carolina was in 2016-17, when he led his team to 26 victories and a spot in the Final Four.


Martin thanked his family for helping him through his recent experience with COVID-19 and also pointed out that he is "in awe of the medical professionals and first responders who continue to courageously battle the coronavirus every day."


"I'm so thankful and appreciative for the well being of my family and my personal health at this time," Martin said, "and I've thought and reflected on the many families who have not been as fortunate."


He ended his message with a note to anyone who has dealt with the coronavirus.


"We have a responsibility to protect, help and care for each other," Martin wrote. "Let's continue to educate ourselves about this virus, and follow the advice of medical professionals and do what we can to prevent the spread. Please reach out to your families and your friends who may be self-isolating, particularly the elderly, so they have someone to talk to and someone to listen. Let's take care of each other and let's keep those who are suffering from this disease and those nurses, doctors and first responders who are fighting for us in our prayers."
