A new wave of Covid-19 is spreading across Asia, with Singapore, Hong Kong, and Thailand witnessing a rise in infections. India has also recorded 257 active covid cases. Kerala, Maharashtra and Tamil Nadu have reported an uptick in active cases over the past few weeks.
The surge in Covid-19 cases in Asia is primarily attributed to the JN.1 variant and its descendants, particularly LF.7 and NB.1.8, which are subvariants of the Omicron lineage.
"Currently, we are seeing an increase in cases attributed to JN.1, which is a subvariant of Omicron. While the symptoms tend to be mild, including fever, cold, cough, and loss of smell or taste, it remains highly contagious," said Dr. Sharad Joshi, Director & HOD, Pulmonology and Paediatric Pulmonology, Max Healthcare.
JN.1 variant: What we know so far
According to the US Centers for Disease Control and Prevention (CDC), the JN.1 variant was first detected in the US in September 2023. It is a descendant of the BA.2.86 variant (an Omicron subvariant). The World Health Organisation (WHO) has classified the JN.1 strain as a "variant of interest" but not yet a "variant of concern."
What are the symptoms of JN.1 strain?
Fever, sore throat, runny nose, headaches, and muscle weakness are some common symptoms of this variant. However, unlike other variants, JN.1 can also cause gastrointestinal problems. Diarrhea, loss of appetite, persistent nausea, and extreme fatigue are a few unique symptoms of JN.1.
Should you be worried?
"There's no need to panic, but exercising caution is essential. A couple of deaths have been reported, so can't take it lightly. It is important to practice caution," Dr Joshi added.
"Though there's no increase in hospitalisations in India, trends in countries like Singapore remind us not to be complacent. We must remain vigilant as this strain can affect all age groups, with extremes of age and those with comorbidities at higher risk," Dr. Sushila Kataria, Senior Director, Internal Medicine, Medanta, Gurugram.
How to stay safe?
"To protect ourselves and those around us, it's important to practice good respiratory hygiene. This includes wearing a mask, covering your nose and mouth when sneezing or coughing, and maintaining a safe distance where possible. It may be wise to avoid non-essential travel, large gatherings, and outings for the time being," advised Dr. Joshi.
"It is crucial for authorities to step up surveillance and for hospitals to resume testing for Covid-19 in respiratory tract infections. At present, there are no specific booster guidelines from Indian authorities," added Dr. Kataria.
He also urged people to stay cautious, monitor trends, and be prepared for any unexpected developments.
