NIH issues advisory on new coronavirus variant

ISLAMABAD: The National Institute of Health (NIH) Wednesday issued an advisory for the prevention and control of JN.1 sub variant of the coronavirus. Initially classified as a "variant of concern," JN.1 has emerged as a worrisome sub variant of the BA.2.86 omicron lineage. This rapidly rising threat is now being reported in numerous countries around the world.

The NIH’s Center for Disease Control issued the advisory to facilitate health authorities for improving preparedness in the prevention and control of the disease. According to the advisory, it is unlikely that JN.1 can produce a situation like the earlier phase of the pandemic, hence its morbidity and mortality are low as of current statistics despite it rapidly replacing other sub variants, and its transmissibility is expected to be high.

The symptoms of JN.1 infection are similar to other sub variants including cough, sore throat, congestion, runny nose, sneezing, fatigue, headache muscle aches, and altered sense of smell. However, symptom presentation depends on an individual's immunity from vaccination and previous infection, the document stated, stressing that ascertaining existing vaccines tests, and treatments still work well against the sub variant.

If someone is sick or has been in close contact with persons having a flu like illness, following preventive measures are recommended for limiting COVID 19 transmission: The NIH declared vaccination the ‘most effective way’ to prevent infection and its severe outcomes, particularly in high risk groups.

The more antibodies with a complete vaccine dose or booster shots, the greater the chances of reducing COVID 19 infection, especially among high risk groups including the elderly population, people with comorbidities, and people working in high risk settings, it added. The NIH recommended enhanced surveillance for influenza like illness (ILI) and severe acute respiratory infections (SARI) which may provide the best chance to detect earlier with prompt response in preventing outbreaks afterwards.

The health authorities have been directed to send all positive samples for genomic sequencing..
