5 symptoms of JN.1 variant

Fever This is a classic symptom of most COVID-19 variants, including JN.1. The fever may be mild or high, and may come and go.

Upper respiratory symptoms These can include runny nose, sore throat, congestion, and cough. While these symptoms are similar to those of a common cold, persistent or worsening respiratory symptoms could be a sign of JN.1.

Extreme fatigue and muscle weakness This is a hallmark symptom of JN.1, with sufferers reporting debilitating fatigue and weakness that makes even basic tasks feel monumental. This type of fatigue differs from the usual tiredness associated with other COVID-19 variants.

Loss of appetite and nausea While digestive issues are less common with JN.1 compared to other COVID-19 variants, loss of appetite and nausea can sometimes occur.

Occasional mild breathlessness Some individuals with JN.1 may experience occasional or infrequent mild breathlessness. If you experience severe or persistent breathlessness, seek immediate medical attention.
