The health department is planning to conduct genomic sequencing on samples to detect possible mutations in chikungunya cases, which have seen a 55% increase this year. Rare symptoms such as hyperpigmentation and neurological issues have been reported, though they are considered extremely uncommon. Co-infection with other viruses like dengue or Japanese encephalitis may be a contributing factor to these unusual symptoms. A rapid action team has been established to investigate the rise in chikungunya cases and issue guidelines for sample analysis at national virology institutes. Samples from patients showing neurological symptoms will be sent for further analysis to determine if there are any mutations present."We will start sequencing as soon as we receive enough samples, particularly from patients in the ICU or with severe symptoms," stated a doctor. Private sector hospitals in the city reported a significant increase in chikungunya cases this year, with some patients requiring hospitalization for up to 10 to 15 days to manage their prolonged fever and associated neurological complications. Children have also been increasingly affected, as evidenced by the admission of an infant to SRCC Children's Hospital in Haji Ali in early August. At Surya Children's Hospital in Santa Cruz, pediatrician Dr. Bhupendra Avasthi noted that children born to mothers who tested positive for chikungunya exhibit hyperpigmentation as a symptom, which is a well-documented characteristic of the disease."
