During a notable 55% increase in chikungunya cases this year, the health department intends to perform genomic sequencing on samples to identify potential mutations. Uncommon symptoms like hyperpigmentation and neurological complications have arisen. Amid a nearly 55% surge in cases of chikungunya viral fever compared to the previous year, the health department has opted to carry out genomic sequencing on select positive samples to investigate any genetic mutations in the virus. Furthermore, state health officials clarified that unusual symptoms such as hyperpigmentation and neurological issues were not new but rather exceedingly rare. Joint director Dr. Mahendra Jagtap mentioned that these symptoms could manifest in chikungunya patients with co-infections of dengue or Japanese encephalitis. The state has established a rapid action team to analyze the reasons behind the escalation in chikungunya cases from 1,702 in 2023 to 2,643 in 2024. Guidelines have been issued to local officials on sample submission for further evaluation at the National Institute of Virology and B J Medical College. The guidelines specify collecting and sending two blood samples from patients displaying neurological symptoms like paralysis and hyperpigmentation for assessment at the Pune institutes. Genomic sequencing will aid in identifying any mutations in the virus. Dr. Rajesh Karyakarte from B J Medical College highlighted the importance of genomic sequencing for mutation detection."We will begin sequencing as soon as we receive sufficient samples, particularly from patients in the intensive care unit or those experiencing severe symptoms," a spokesperson stated. Private sector doctors in the city reported a significant rise in chikungunya cases this year, with some patients requiring hospitalization to manage prolonged high fevers and neurological complications. Children have also been increasingly affected this year, with an eight-month-old boy being admitted to SRCC Children's Hospital in Haji Ali in early August. Dr. Bhupendra Avasthi, a pediatrician at Surya Children's Hospital in Santa Cruz, noted that children born to chikungunya-positive mothers may exhibit hyperpigmentation as a symptom, which is well-documented in chikungunya cases."
