The Mayo Clinic says there are currently about 12,000 workers at its Mayo Clinic-affiliated hospitals who are potentially at risk of contracting toxoplasma.
The Mayo Clinic, which is part of the Mayo Clinic Health System, said it received a call from a woman who had contracted toxoplasmas from an employer, but said she was too ill to work.
“We were told she was a pharmacist and she needed to be tested for toxoplasms and we need to do more testing,” the company said in a statement.
“We are calling on all employees and their families to contact their employers and request to test for the virus.”
A spokeswoman for the Mayo Children’s Hospital said it was working with its employees to make sure they had been vaccinated.
Toxoplasmas are highly contagious, and if left untreated can cause the disease to spread through the blood stream and cause death.
A spokesperson for the American Red Cross said it is working with the Mayo Hospital on a vaccine for toxoplastons.
Health authorities are urging people to get vaccinated before the flu season begins.
People can also call 1-800-CDC-INFO if they have questions.
