The ascendant strain driving nan summation is JN.1, accounting for 53% of sequenced samples. A subvariant of nan Omicron BA.2.86 lineage, JN.1 is known for its enhanced transmissibility and mean immune evasion.
Symptoms stay accordant pinch erstwhile Omicron infections—sore throat, fatigue, mild fever, headache, and musculus aches—and typically resoluteness wrong 4 days.

New Omicron subvariants substance nan surge
The ascendant strain driving nan summation is JN.1, accounting for 53% of sequenced samples. A subvariant of nan Omicron BA.2.86 lineage, JN.1 is known for its enhanced transmissibility and mean immune evasion.
Closely tracked by scientists, it is joined by emerging variants NB.1.8.1 and LF.7—both precocious detected successful Tamil Nadu and Gujarat, respectively.

Symptoms mild but dispersed is simply a worry
