Overview of COVID Variant JN.1 and Symptoms to Look Out For
As COVID cases rise, a new variant called JN.1, a descendant of the omicron family substrain BA.2.86, is rapidly spreading in the U.S. and other countries. Detected in September, JN.1 is now responsible for over 20% of all COVID cases, showing a significant increase from previous reports. The CDC notes that its rapid spread suggests it may be more transmissible or better at evading existing immunities.
While there is no evidence that JN.1 causes more severe illness than other variants, it is essential to recognize its symptoms. Common symptoms of a JN.1 COVID-19 infection include cough, sore throat, headache, muscle aches, fever, change in or loss of taste or smell, congestion, runny nose, fatigue, “brain fog,” and gastrointestinal symptoms like upset stomach and mild diarrhea. These symptoms may overlap with those of the flu, cold, or respiratory infections.
It is crucial to be aware that the severity and type of symptoms depend on individual immunity and health history rather than the specific variant. Shortness of breath and difficulty breathing are signs of a more serious infection that requires immediate medical attention.
Despite its mutated form, the latest COVID-19 vaccines and treatments are expected to work against JN.1. As COVID continues to evolve, staying informed about new variants and following preventive measures remains essential in managing the ongoing pandemic.
