Eczema is a common allergic disease in children, which seriously affects the quality of life of children and their families.

The results showed that the incidence of very-early-onset eczema was 12.4%. Primiparity was associated with a higher risk of eczema [risk ratio (95% confidence interval): 1.23 (1.06–1.42)].

Very-early-onset eczema is common. Given its adverse impact on children’s health and life quality, this previously neglected public health issue needs to be prioritized. In addition, maternal parity could serve as an indicator in risk assessment and prediction for infant eczema.

An increasing number of studies have projected temperature-related mortality, but few consider the change of population’s adaptability to future temperature and mortality burden from cold and heat effects.

This study offers a comprehensive characterization of human adaptability and excess mortality burden of temperature across various regions of China.

The temperature-related excess mortality was projected to increase in the 2050s and decrease in the 2080s. Heat adaptability was projected to increase in the future, but along with the rising temperatures, the heat-related excess mortality continuously rose, except for the low-speed rising scenario. Although the excess mortality of cold was projected to decrease in the nearer future, it might not keep declining in the long run, due to the decreasing cold-adaptability, which deserves more attention.

The norovirus has often caused outbreaks in schools and kindergartens, but minimal research has been performed on environmental contamination during norovirus outbreaks in schools and kindergartens.

This report conveys the norovirus detection rates and viral loads in different environmental sites in 45 norovirus outbreaks in Beijing Municipality from October to December 2020.

The evidence presented here can instruct professionals and the public to sample and disinfect key locations of the environment purposefully when responding to norovirus outbreaks.
