Abstract
Kawasaki disease (KD, typical/atypical/partial) admissions (n = 644) were surveyed from 2017 to 2020 and compared to urinary tract infection (UTI) admissions and COVID-19 in 2020. KD admissions decreased by 27% and median KD age decreased in 2020, whereas UTI admissions remained steady. KD admissions showed a seasonality with a peak in April and nadir in February-March. All KD/KD-related pediatric intensive care unit cases tested negative for COVID-19, and no multisystem inflammatory syndrome in children was found.

Abstract
Infections caused by respiratory syncytial virus (RSV) are a major cause of morbidity and mortality in young children worldwide. Understanding seasonal patterns of region-specific RSV activity is important to guide resource allocation for existing and future treatment and prevention strategies. The decades of excellent RSV surveillance data that are available from the developed countries of the world are incredibly instructive in advancing public health initiatives in those regions. With few exceptions, these developed nations are positioned geographically across temperate regions of the world. RSV surveillance across tropical regions of the world has improved in recent years, but remains spotty, and where available, still lacks the necessary longitudinal data to determine the amount of seasonal variation expected over time. However, existing and emerging data collected across tropical regions of the world do indicate that patterns of infection are often quite different from those so well described in temperate areas. Here, we provide a brief summary regarding what is known about general patterns of RSV disease activity across tropical Asia, Africa and South America, then offer additional country-specific details using examples where multiple reports and/or more robust surveillance data have become available.
