5 signs of infection with the Covid JN.1 variant

The Covid JN.1 variant can cause fever, runny nose, sore throat, headache, restlessness, loss of appetite and sleep disorders.

In the past few weeks, the world has recorded a sudden increase in the number of Covid-19 cases, mainly related to the JN.1 variant. This variant is highly infectious and is considered a “variant of concern” by the World Health Organization (WHO).

JN.1 is derived from BA.2.86, a sub-strain of Omicron. It possesses a distinct mutation in the spike protein (responsible for entering and infecting cells) and mutations in other regions. According to the latest data from the UK, this is the fastest growing variant, with a weekly rate of 84.2%.

The health monitoring application ZOE Health Study says the 5 most common symptoms of JN.1 are runny nose, sore throat, headache, sleep disturbance and restlessness. Other symptoms include fever with muscle pain, loss of appetite, fatigue, nausea and vomiting, and persistent cough.

Experts recommend that people with symptoms, especially when JN.1 spreads rapidly, should consult a doctor for support. At the same time, everyone should comply with public health measures such as wearing masks and keeping distance in crowded places. Vigilance, early detection and flexible response are very important in managing and minimizing the impact of mutations.

WHO has not yet made a statement on the severity of the patient after being infected with JN.1. However, research published in the journal Cell in early January showed that JN.1 can infect cells in the lower lung area, making symptoms worse. According to experts, JN.1 adheres to cells more effectively and participates in host cell membrane fusion.

To avoid JN.1 infection, experts recommend:

– Maintain personal hygiene: regularly wash hands with soap and water for about 20 seconds, disinfect with alcohol.

– Wear a mask: Make sure to use a medical mask, MN-95 mask, covering your nose and mouth, especially in public spaces where physical distancing is difficult.

– Vaccination: one of the main tools to avoid health complications related to JN.1 is vaccination. Experts recommend two standard injections and a booster dose.

In some Southeast Asian countries, governments have taken specific actions to limit the spread of mutations. Indonesia has installed thermal scanners at Jakarta’s main international airports and the Batam ferry terminal to screen travelers. Ms. Naning Nugrahini, head of the airport port health office, said people found to have symptoms will need further rapid testing.

Recently, the Ho Chi Minh City infectious disease surveillance system recorded 12/16 Covid patients hospitalized in December infected with JN.1 , one case infected with JN.1.1.
