What Is JN.1? Here’s Everything You Need to Know About the Latest COVID-19 Variant

A report by the Centre for Disease Control and Prevention (CDC) has flagged a new COVID-19 variant named JN.1.

JN.1 is a new, highly mutated strain which is a descendant of Omicron, specifically the BA.2.86 (Pirola) variant. It is not widespread currently, but it appears to be growing in Europe, United States and India.

The United States was the first country to report JN.1 in September. Since then, 11 other countries, including UK, Iceland, Portugal, Spain, and the Netherlands, have recorded the new COVID-19 variant. JN.1 and BA.2.86 are uncommon COVID-19 variants in the US. Presently, JN.1 makes up less than 0.1 per cent of SARS-CoV-2 viruses.

 India saw a single-day surge in the number of Covid-19 cases to 702, with the number of active cases rising to 4,097, the health ministry said in a statement on Thursday (Dec 28).

Six deaths have been reported in the country in the last 24 hours: two from Maharashtra and one each from Karnataka, Kerala, West Bengal and Delhi, news agency PTI reported citing health ministry’s data updated at 8 am local time. Due to the open border, the increase in covid cases in India directly affects the Nepal public health,

Here’s everything you need to know about the new COVID-19 variant named JN.1. 

What is JN.1 COVID-19 variant?

The CDC is still researching and learning about the new COVID-19 variant. However, they do know a little about what JN.1 looks like.

JN.1 differs from its predecessor, BA.2.86, by a mutation in the spike protein, which helps the virus infect cells. 

Dr Thomas Russo, professor and chief of infectious diseases at the University of Buffalo in New York, told Prevention.com, “BA.2.86 has more than 20 mutations on the spike protein, and there was a concern when we detected it first a while back that, wow, this might be a real problem.”

According to Dr Russo, JN.1 could be more challenging to detect. He described the new variant as “quite devious.”

However, as per the latest data by CWC, BA.2.86 did not spread quickly or dodge our immunity. It also says that the updated 2023-2024 COVID-19 vaccines appear to block it. They also expect the new COVID-19 variant, JN.1, to be similar. 

Symptoms of JN.1 COVID-19 Variant

JN.1 has similar symptoms to previous COVID-19 variants. Below are the symptoms of the JN.1 COVID-19 variant, according to the CDC. 

• Fever or chills
• Cough
• Shortness of breath or difficulty breathing
• Fatigue
• Muscle or body aches
• Headache
• Loss of taste or smell
• Sore throat
• Congestion or runny nose
• Nausea or vomiting
• Diarrhea

To protect yourself from the JN.1 COVID-19 variant, people must stay updated with the latest vaccines. Steve Russell, NHS director of vaccinations and screenings, said, “With concerns arising over new COVID variants, it’s vital to adapt the [vaccination] program and bring it forward for those most at risk.” He added, “I strongly urge everyone eligible to come forward as soon as they can for this important protection in colder months.”
