An occasional nocturnal cough may indicate a parasite infection.
Such a symptom may be related to roundworms, said virologist Alexander Lukashev in an interview with AiF. If a nightly cough has been bothering you for weeks, you should look for other causes. Another "side effect" is that in certain diseases the person's condition may improve. "Some parasites reduce symptoms of allergies and even asthma," he added.
Most often, with parasitic diseases, there are no symptoms at all, or they are mild and non-specific: weakness, allergic reactions, indigestion. A virologist spoke about the probable picture of the disease against the background of a case in the Saratov region: 19 people were infected with opisthorciasis after eating dried fish, seven were hospitalized.
