In the context of multiple sclerosis (MS), acute episodes or flare-ups can be triggered by various factors. Here we analyze the potential triggers provided in your options:

1. Stress: Stress is widely recognized as a potential trigger for exacerbations in individuals with MS. Psychological stress can affect the immune system and trigger inflammatory responses that may lead to relapses.

2. Infections: Infections, particularly viral infections like the flu or respiratory infections, are one of the most common triggers for acute episodes in MS patients. Infections can provoke the immune system, leading to increased inflammation and worsening of symptoms.

3. Pregnancy: While pregnancy itself does not directly trigger MS episodes, it can influence disease activity. Many women experience a reduction in MS relapses during pregnancy, particularly in the second and third trimesters, but they may see an increase in relapse rates postpartum.

Summary

Both stress and infections are recognized triggers for acute episodes of MS. While pregnancy affects the disease's course, it is not a direct trigger in the same way as the other two factors.

Final Answer

The triggers of acute episodes of MS include stress and infections.
