Chikungunya fever is a benign, self-limiting, acute viral illness. An epidemic occurred in New Delhi, India, in August and September 2016. We observed many cases with atypical cutaneous features mimicking Stevens-Johnson syndrome and toxic epidermal necrolysis during this epidemic, especially in infants and children. Twenty-one children (13 [61.9%] boys, 8 [38%] girls) presenting with vesico-bullous and necrotic lesions were reviewed. Cutaneous presentation included vesicles and bullae with purpuric macules and necrosis, seen in 16 (76%) patients. Skin lesions resolved in 5-7 days, leaving behind hyperpigmentation in seven (33.3%) patients and hypopigmentation in three (14.2%). Minor oral erosions were observed in three (14.2%) patients, and palmoplantar erythema was seen in four (19.04%). It is essential for dermatologists to understand the Stevens-Johnson syndrome and toxic epidermal necrolysis-like presentation of chikungunya and not to misinterpret it as true Stevens-Johnson syndrome and toxic epidermal necrolysis, which will lead to unnecessary intervention and management.

The Yamuna River is the backbone of domestic, irrigation, and industrial activities in Delhi, India, yet the complex dynamics of its microbes and their contribution to biogeochemical cycles in a polluted environment remain elusive. This is an introductory report describing the microbial community in the Yamuna River, using high-throughput metagenomics.

Several studies in the recent past reported new sources for industrial persistent organic pollutants (POPs) from metropolitan cities of India. To fill the data gap for atmospheric polybrominated diphenyl ethers (PBDEs), polyurethane foam disk passive air sampling (PUF-PAS) was conducted along urban-suburban-rural transects in four quadrilateral cities viz., New Delhi, Kolkata, Mumbai and Chennai from northern, eastern, western and southern India respectively. Average concentration of Σ8PBDEs in pg/m(3) for New Delhi, Kolkata, Mumbai and Chennai were 198, 135, 264 and 144 respectively. We observed a distinct urban > suburban > rural trend for atmospheric PBDEs in Mumbai. Principal component analysis (PCA) attributed three different source types. BDE-47, -99, -100, -153 and -154 loaded in the first component were relatively high in the sites where industrial and informal electronic waste (e-waste) recycling activities were prevalent. Penta congener, BDE-99 and tetra congener, BDE-47 contributed 50%-75% of total PBDEs. Ratio of BDE-47 and -99 in Indian cities reflected the usage of penta formulations like Bromkal -70DE and DE-71 in the commercial and electrical products. PC-2 was loaded with BDE-28 and -35. Percentage of BDE-28 and BDE-35 (>10%) were comparatively much higher than commercial penta products. Abundance of BDE-28 in majority sites can be primarily due to re-emission from surface soil. PC-3 was loaded with BDE-183 and elevated levels were observed mostly in the industrial corridor of Indian cities. BDE-183 was notably high in the urban industrial sites of New Delhi. We suspect this octa-BDE congener resulted from recycling process of plastic products containing octa-BDE formulation used as flame retardants.

Group C Rotavirus (RVC) is an enteric pathogen responsible for acute gastroenteritis in children and adults globally. At present there are no surveillance studies on group C Rotaviruses in India and therefore their prevalence in India remains unknown. The present study aimed to evaluate group C rotavirus infection among <5 years old children hospitalized with acute gastroenteritis in New Delhi.
