Abstract Background COVID-19 has posed an enormous threat to public health around the world. Some severe and critical cases have bad prognoses high case fatality rates, unraveling risk factors for are of significance predicting preventing illness progression, reducing rates. Our study focused on analyzing characteristics exploring developing COVID-19. Methods The data this was disease surveillance symptomatic reported from 30 provinces in China between January 19 March 9, 2020, which...

Background: Lichen sclerosus (LS) is a chronic inflammatory dermatosis that occurs mainly in the anogenital area and causes itching, soreness, atrophy scarring, which may result burying of clitoris females phimosis males. Photodynamic therapy (PDT) has been suggested during past years as an alternative non-invasive treatment for LS, but there still no meta-analysis to evaluate its efficacy safety. Aims: To assess safety 5-aminolevulinic acid photodynamic (ALA-PDT) LS. Methods: We undertook...

Abstract We estimated the symptomatic, PCR-confirmed secondary attack rate (SAR) for 2,382 close contacts of 476 symptomatic persons with coronavirus disease in Yichang, Hubei Province, China, identified during January 23–February 25, 2020. The SAR among all was 6.5%; who lived an index case-patient, 10.8%; close-contact spouses case-patients, 15.9%. varied by contact age, from 3.0% those <18 years age to 12.5% >60 age. Multilevel logistic regression showed that factors significantly...
