Common virus could speed up cystic fibrosis

0 0

A new study has found that cytomegalovirus, which is normally dormant in people who have it, can become active again in people with cystic fibrosis who develop lung infections.

Cystic fibrosis is an inherited condition. It causes damage to the lungs and digestive system, and it is life-threatening.

Common symptoms of cystic fibrosis include persistent coughing, inflamed nasal passages, wheezing, breathlessness, severe constipation, and lung infections.

Cystic fibrosis occurs due to a gene mutation that affects the protein that regulates the movement of salt in and out of cells.

The mucus, which is normally thin and slippery, becomes sticky and thick and clogs the tubes that carry air in and out of the lungs.

This makes it hard to cough the mucus out of the lungs. Breathing can become difficult and cause complications including chronic lung infections, nasal polyps, coughing up blood, respiratory failure, diabetes, and reproductive system complications.
