Although the government maintains that the disease remains endemic and doesn’t currently pose an immediate threat, the question remains: what are these new variants, and how do they differ from previous ones? While the JN.1 variant shares many similarities with previous Omicron sub-variants, two key characteristics distinguish it: Let’s understand this new virus and what to do if you experience these new symptoms, according to Jaipur-based physician Dr Anil Sharma.
What is the JN.1 COVID-19 Variant?
JN.1 is actually a sub-variant of Omicron. It is derived from the BA.2.86 variant, also known as Pirola. It was first detected in Luxembourg in 2023 and has since spread gradually to other parts of the world, now reaching India. JN.1 is said to spread faster than previous variants. This is because of specific mutations in its spike protein, making it easier to bind to human cells. In simpler terms, it can infect us more easily than before.
Common Symptoms of JN.1
– Fever or chills– Dry cough
– Sore throat
– Fatigue
– Headache
– Runny or stuffy nose
– Muscle aches
– Difficulty breathing (in severe cases)
Two New Unique Symptoms of COVID emerge
1. Persistent Low-Grade Fever
While previous COVID variants often presented with high fever, sweating, and shivering, JN.1 infections frequently exhibit a persistent low-grade fever. This typically ranges between 37.6 ∘C and 38.1 ∘C (99.6−100.5 ∘F). This fever won’t be accompanied by rapid breathing or feeling intensely hot to the touch. You might feel mildly warm for several days, but the fever won’t fluctuate dramatically as seen in previous COVID waves. This symptom can be easily overlooked, mistaken for mild fatigue or another minor ailment. However, this persistent low-grade fever indicates the body is fighting the virus, just less intensely. Recognising this is crucial for prompt testing and preventing further spread.
2. Gastrointestinal Issues
Another distinguishing symptom of JN.1 is a higher incidence of gastrointestinal problems. This includes nausea, loss of appetite, abdominal discomfort, and diarrhoea. While gastrointestinal symptoms were present in previous COVID-19 variants, they were less common and often milder. In JN.1, these symptoms are more prominent and appear in a larger percentage of patients. Jaipur-based physician Dr Anil Sharma believes this could be due to changes in how the virus interacts with the body or its response to the gut’s immune system. Gastrointestinal symptoms can sometimes appear alongside or even precede respiratory symptoms like cough and sore throat, unlike previous strains. The positive aspect is that this strain hasn’t yet shown significant respiratory complications.
