Tennis elbow pain, numbness, and tingling have become common symptoms of the Zika virus in recent months.
The pain and tingle are similar to those experienced by people who have been infected with the virus, but they don’t necessarily indicate a direct relationship to the virus.
They are a symptom of a wider problem: Zika has affected the immune system of many athletes.
A study published in the American Journal of Sports Medicine in December found that athletes in Brazil, the United States, and other nations have had problems with their immune systems due to the Zika infection.
It’s unclear how many of the athletes affected are still active or how many will require long-term medical care, but a recent study of athletes at the University of Utah showed that they had elevated levels of antibodies to Zika in their blood.
In some cases, the increased levels of Zika antibodies are associated with severe illness.
That’s why some athletes have tried to minimize exposure to mosquitoes, which can transmit the virus from person to person, by wearing long-sleeved shirts and avoiding wearing clothing that exposes their skin.
But even if athletes are avoiding mosquito bites, they may still be at risk for more serious problems.
For example, the International Olympic Committee has not officially designated Zika as a WADA prohibited disease.
And while athletes may be able to avoid Zika by wearing protective gear, they should also consider getting tested for the virus and treating any symptoms, especially if they experience fever, soreness, or pain.
