Scientists are watching a new highly contagious COVID variant that appears to be causing a new symptom in children.

XBB.1.16, an Omicron variant that’s been given the name“Arcturus,” is behind a surge in infections in India. Forbes reported. The country is seeing a rise in pediatric cases particularly with a new symptom, . according to Dr. Vipin Vashishtha, a pediatrician in India and former head of the Indian Academy of Pediatrics Committee on Immunization.

Vashishtha told Forbes pediatric COVID cases are on the increase for the first time in six months and “an infantile phenotype seems emerging.”

Symptoms reported in children are:

• High fever
• Cough
• “Itchy” conjunctivitis or pinkeye without pus, but with “sticky eyes”

The latter symptom hasn’t been widely reported in previous COVID waves.

Symptoms of conjunctivitis include:

• Tearing or watery eyes
• Redness
• Swelling
• Pain or irritation
• Itching
• Discharge

The variant isn’t currently spreading widely in the U.S. CDC data shows that XBB.1.16 accounts for less than 1% of cases nationally but is being monitored by the health agency. The World Health Agency is also monitoring, designating XBB.1.16 as a “variant under monitoring.”

While it spreads easily, scientists said they don’t expect XBB.1.16 to be more lethal than other types of variants and will likely cause a much milder illness that resembled the flu.
