The MLB season isn't even a week old and the league is facing their first significant outbreak of COVID-19. Multiple players from the Marlins, including Sunday's starter Jose Urena, tested positive for the virus over the weekend, forcing Miami to delay their flight home and cancel their home opener. Pinpointing the origin and the starting point of the initial COVID-19 case could prove tricky due to the possibility of asymptomatic or presymptomatic transmission. Travel complicates the issue as players are forced into smaller spaces like buses and planes with a potential infected teammate. The situation with Miami, and possibly Cincinnati, is a harsh reminder that even with daily testing, players are going to catch the virus and spread it amongst their team. How the league and its players respond to an outbreak ultimately will determine how long this season is able to last.
The Red Sox pitcher remains out indefinitely as he battles a COVID-19-related issue. Rodriguez contracted the virus in early July and experienced a headache and high fever. While these symptoms have subsided, the battle with coronavirus left Rodriguez with myocarditis. As researchers learn more about COVID-19 they are finding that the virus can impact other organs and organ systems outside the lungs and respiratory system, including the heart.
The heart is surrounded by a protective sac known as the pericardium. Layers of the pericardium fuse with the outer wall of the heart. The heart wall is multilayered, including a thick layer of myocardial tissue.
