Can the flu cause neurological problems?

Influenza can be associated with various neurologic problems: encephalopathy (a state of confusion), seizures, neuropathy, as well as others. These complications most frequently occur in children, although cases of neurologic illness associated with adult influenza certainly occur.

What happens when a virus attacks the heart?

Myocarditis can affect your heart muscle and your heart’s electrical system, reducing your heart’s ability to pump and causing rapid or abnormal heart rhythms (arrhythmias). A viral infection usually causes myocarditis, but it can result from a reaction to a drug or be part of a more general inflammatory condition.

Can viral myocarditis go away?

In many people with uncomplicated viral myocarditis, the heart muscle changes improve without specific therapy and myocarditis-related EKG and echocardiogram abnormalities eventually disappear. However, more severe forms of myocarditis can cause permanent damage to the heart muscle.

Can the flu cause long term side effects?

What damage does the flu do to your body?

It is well-known that muscle aches and weakness are prominent symptoms of influenza infection. Our study in an animal model found that influenza infection leads to an increase in the expression of muscle-degrading genes and a decrease in expression of muscle-building genes in skeletal muscles in the legs.
