Naval Special Warfare Center at Naval Amphibious Base Coronado, has suspended training for three of the 11 current SEAL and SWCC classes. The decision was made on March 16 and will last for eight consecutive weeks.

The classes that were temporarily suspended were those that were in the earlier phases of training.

The First Phase of Basic Underwater Demolition/SEAL (BUD/S) and the Basic Crewman Training (BCT) segment of the SWCC pipeline expose students to very harsh conditions. Spending extended periods of time in cold water, along with physical fatigue and sleep deprivation, can create symptoms similar to COVID-19 and result in students being immunocompromised.

During Hell Week and other training evolutions, because of the amount of time spent immersed in water combined with physical exertion, it is not unusual for students to develop swimming-induced pulmonary edema (SIPE). SIPE occurs when blood vessels in the lungs leak fluid and blood into the alveoli (airspaces). This condition causes wheezing, crackling, shortness of breath, and the spitting up of blood.
