Certainly, the girl famous that she felt a milder type of shortness of breath after swimming within the sea two weeks earlier than and through different bodily actions. “I simply assumed I used to be somewhat underneath the climate,” she mentioned within the report.

Wilmshurt, who was not concerned within the report, additionally mentioned it was unlikely that the vaccination induced the fluid within the coronary heart muscle, given the brief time between the injection and the onset of signs. Though it was not possible to say whether or not it was brought on by the IPE or was a pre-existing situation, he mentioned he suspected the previous.

Dr. Doug Watts, medical director of DDRC Healthcare, a specialist in diving medication, mentioned individuals ought to pay attention to IPE and get out of the water instantly and search medical consideration in the event that they expertise uncommon shortness of breath whereas swimming. “You probably have one episode, you are prone to have one other episode, and the following one could possibly be deadly,” he mentioned.
