Human infection with avian influenza A(H7N9) virus in China – update

Since March 2013, when the avian influenza A(H7N9) virus infection was first detected in humans, a total of 1567 laboratory-confirmed human cases, including at least 615 deaths1, have been reported to WHO (Figure 1) in accordance with the International Health Regulations (2005). In the latest wave (the 6th wave since Oct 2017), only three human cases have been detected; meanwhile there have been generally fewer A(H7N9) virus detections in poultry and environment samples, according to various reports from mainland China and China, Hong Kong SAR. WHO has been monitoring the situation, and conducting risk assessments2 through its Global Influenza Surveillance and Response System (GISRS), which comprises more than 150 institutions in 114 countries. These institutions actively and routinely exchange information and materials, e.g. reference viruses (seasonal, zoonotic and pandemic viruses), serology panels and reagents for risk assessment and development of countermeasures.

CONCLUSIONS: This single practice study showed total patient contact was similar over both sample periods, but most contact in 2020 was virtual. Further longitudinal multi-practice studies to confirm these findings and describe future consultation patterns are needed to inform general practice service delivery post-COVID-19.

This study therefore investigated the impacts of RRCC on air pollution based on detailed household heating data obtained from intensive face-to-face interviews in Shandong province, China. The total contributions and specific contributions of coal, stoves, and coal-stove combinations to air pollution were simulated using the WRF-CAMx-PSAT model. The RRCC for heating had a considerable impact on air pollution, contributing 36.1, 9.1, and 16.1% of atmospheric SO2, NOx, and PM2.5 in winter, respectively. Different coal-stove combinations had different impacts on air pollution and mitigation efficiencies. The combination of bi...

Abstract Limited studies focus on the occurrence, removal rate and seasonal variation of substituted diphenylamine antioxidants (SDPAs) in surface water and wastewater in China. In this paper, the detection method of SDPAs was established by the ultra-performance liquid chromatography-tandem mass spectrometry. Daily variations suggested that significant variations were found for the concentrations of some SDPAs in the influent. It was found that the SDPAs could be detected in all the effluent samples and C8/C8-DPA was the predominant compound in two WWTPs. The levels of most SDPAs in the effluent were much lower t...

ahesh Influenza A viruses (IAVs) are a major cause of respiratory illness and are responsible for yearly epidemics associated with more than 500,000 annual deaths globally. Novel IAVs may cause pandemic outbreaks and zoonotic infections with, for example, highly pathogenic avian influenza virus (HPAIV) of the H5N1 and H7N9 subtypes, which pose a threat to public health. Treatment options are limited and emergence of strains resistant to antiviral drugs jeopardize this even further. Like all viruses, IAVs depend on host factors for every step of the virus replication cycle. Host kinases link multiple signaling pathways ...
