Covid Returns: New Variant JN.1 evades immune system more effectively…….

Chennai / New Delhi: It is noteworthy that the Covid- JN.1 variant evades the immune system more effectively than Omicron and other variants contributing to increased transmission, indicating higher infectivity said Dr. Naresh Purohit , Advisor – National Communicable Disease Control Programme.

Noted Epidemiologist Dr. Purohit told NewsOnRadar.com after addressing a National Workshop on “War Against Covid Variants” organised by the Chennai based
Dr. MGR Medical University , that even though the number of cases of Covid- JN.1 is rising in the country there is no cause of immediate concern as 92 per cent of those infected are opting for home-based treatment, indicating a mild illness.
Principal Investigator for the National Integrated Disease Surveillance Programme (NIDSP) Dr. Purohit averred that individuals with underlying health conditions (e.g., those aged 65 and older, children, diabetes, bronchitis or asthma, heart patients, cancer patients) should exercise extra caution when venturing outside.
He cautioned that if someone in these vulnerable groups experiences flu-like symptoms, prompt medical attention is advised due to their lower immunity.
Renowned Infectious Disease Expert pointed that currently, there’s no evidence suggesting the severity of the JN.1 variant is higher than other Omicron variants. It appears to be milder, with the only concerning factor being its increased infectivity.

“The heightened infectivity is seen as a normal evolutionary process for viruses, where they spread more easily but tend to cause less severe illness. This is crucial for the virus’s survival and continued transmission.” he explained.

“The overall fatality or lethality rate seems to be decreasing with virus evolution, indicating a trend where viruses become less deadly over time to ensure their own survival by infecting more people.” he said

He emphasized that the current situation does not indicate severe outcomes, but individuals in high-risk groups should remain vigilant and take necessary precautions.
Promote a robust immune system through a wholesome lifestyle, including a balanced diet, consistent exercise, and sufficient sleep, and seek guidance from healthcare professionals for immune-boosting strategies, particularly for cancer patients on treatment.

He advised to maintain optimal blood sugar levels by consistently monitoring and collaborating with healthcare professionals if one has diabetes.

“Adopt a well-balanced diet, participate in regular physical activity, and effectively manage stress for overall diabetes management.” he added

He stressed to follow thorough preventive measures, such as consistent 20-second handwashing, maintaining safe distances in crowded places, steering clear of close contact with those who are unwell, and wearing masks in public, ensuring proper coverage of both the nose and mouth.
He averred that vaccination is essential in enabling the immune system to identify and counteract harmful pathogens, averting severe illness, curbing disease transmission, and protecting both individual and community well-being.
