Abstract Background The prediction of coronavirus disease in 2019 (COVID-19) in broader regions has been widely researched. but for specific areas such as urban areas the predictive models were rarely studied. It may be inaccurate to apply predictive models from a broad region directly to a small area. This paper builds a prediction approach for small size COVID-19 time series in a city. https://herbsdailyes.shop/product-category/policosanol/
