Mosquito-borne viruses, including dengue virus (DENV), chikungunya virus (CHIKV), and Zika virus (ZIKV), pose major threats to public health in tropical and subtropical regions worldwide. Neonates are particularly vulnerable, and the associated disease burden has drawn increasing attention. Routes of neonatal infection include vertical mother-to-child transmission (transplacental and peripartum) and postnatal mosquito bites. Clinical manifestations are often nonspecific; a proportion of cases may progress to central nervous system infection, hemorrhagic disease, or long-term neurodevelopmental impairment, with serious consequences for survival and quality of life. Although China has issued prevention and control guidelines for adults and pregnant women, systematic clinical guidance tailored to neonates remains lacking. In response, the Perinatal Group of the Pediatric Branch of the Chinese Medical Doctor Association convened a multidisciplinary panel to develop this expert consensus, integrating the latest international evidence with China's practical prevention and control experience. The consensus addresses epidemiology; the effects of maternal infection on fetuses and neonates; clinical manifestations; diagnosis and differential diagnosis; early warning indicators of severe disease; therapeutic strategies and supportive care; and prevention and maternal-infant management. It aims to provide evidence-based, standardized, and practical guidance for frontline clinicians managing neonatal mosquito-borne viral infections.

Chikungunya is caused by an arbovirus transmitted by Aedes mosquito vector. With the increase of habitat of mosquito by global warming and frequent international travel and interchange, chikungunya reemerged and showed global distribution recently. Until now there has not been reported any case infected with chikungunya virus in Korea. A 23-year-old man has been the Republic of the Philippines for 1 week, and visited our emergency center due to fever and back pain. Chikungunya viral infection was diagnosed by specific IgM for chickungunya virus by enzyme-linked immunosorbent assayin Korea Centers for Disease Control and Prevention. His clinical course was self limited. We introduce the first imported case infected with chikungunya virus in Korea.

This report describes the chikungunya cases and local transmission detected in Brunei Darussalam for the first time, despite the country being situated in a region that has experienced a multitude of outbreaks over the years. A combined strategy of active case detection, patient isolation and vector control measures was deployed in an attempt to avert further transmission. The findings have important public health implications for international surveillance and control strategies for this re-emerging disease.
