  • 简介:AbstractBackground:Understanding the global spatiotemporal pattern of seasonal influenza is essential for influenza control and prevention. Available data on the updated global spatiotemporal pattern of seasonal influenza are scarce. This study aimed to assess the spatiotemporal pattern of seasonal influenza after the 2009 influenza pandemic.Methods:Weekly influenza surveillance data in 86 countries from 2010 to 2017 were obtained from FluNet. First, the proportion of influenza A in total influenza viruses (PA) was calculated. Second, weekly numbers of influenza positive virus (A and B) were divided by the total number of samples processed to get weekly positive rates of influenza A (RWA) and influenza B (RWB). Third, the average positive rates of influenza A (RA) and influenza B (RB) for each country were calculated by averaging RWA, and RWB of 52 weeks. A Kruskal-Wallis test was conducted to examine if the year-to-year change in PA in all countries were significant, and a universal kriging method with linear semivariogram model was used to extrapolate RA and RB in all countries.Results:PA ranged from 0.43 in Zambia to 0.98 in Belarus, and PA in countries with higher income was greater than those countries with lower income. The spatial patterns of high RB were the highest in sub-Saharan Africa, Asia-Pacific region and South America. RWA peaked in early weeks in temperate countries, and the peak of RWB occurred a bit later. There were some temperate countries with non-distinct influenza seasonality (e.g., Mauritius and Maldives) and some tropical/subtropical countries with distinct influenza seasonality (e.g., Chile and South Africa).Conclusions:Influenza seasonality is not predictable in some temperate countries, and it is distinct in Chile, Argentina and South Africa, implying that the optimal timing for influenza vaccination needs to be chosen with caution in these unpredictable countries.

  • 简介:AbstractAnti-influenza drugs are one of the most critical pathways for control of influenza virus infection. Drugs that have been developed or are developing may function via different mechanisms, and so far, inhibitors of influenza virus polymerase are among the most promising types of drugs. Favipiravir and Baloxavir, also named T-705 and Xofluza respectively, have been approved for influenza treatment in Japan and the United States. Favipiravir effectively and selectively inhibits the RNA-dependent RNA polymerase (RdRp) of RNA viruses while Baloxavir specifically targets the cap-dependent endonuclease PA of influenza viruses. These two drugs have been suggested as the first candidate drugs for influenza infection treatment, especially for strains resistant to other anti-influenza drugs. This review will focus on the pharmaceutical mechanisms and anti-influenza activity of these two drugs.
