An enlargement of the heart often is due to a heavier than normal workload. For example, as one ages (normal aging, slight enlargement) blood vessels are less flexible and become narrower due to some buildup of plaque. One's system compensates by enlarging the heart that works harder to compensate and reduce the intraventricular pressures.
With good heart muscle, it indicates heart contractions will/should meet system's demand for oxygen-rich blood. The echo indicates valves are good. If either conditons were insufficient cardiac output would be compromised causing the heart to work harder and enlarge. So those conditions can be ruled out.
So the problem should be due to the afterload that requires an abnormal strain on the heart to meet demand. I don't believe it is a stretch there is an abnormal and increased demand for blood/oxygen to overcome a fever and medication for the conditions you state which causes a harder working heart.
The heart muscle is not unlike the skeletal muscle. If you stressfully exercise a skeletal muscle it will pump up and immediately enlarge and in a short time reduce back to normal. But if the stressful exercise is over a longer time the muscle will enlarge and not reduce in size in a short time. With the heart, it would/could require medications for relief.
