Summary: The Philippine coconut industry, characterized by high poverty rates among small-scale coconut farmers, was severely impacted by a super typhoon in 2013. The typhoon significantly reduced the income of coconut farmers, requiring 7-9 years for full production capacity to recover. Farmers coped by exploring other income sources.

Summary: This study reported the long-term surveillance of avian influenza viruses (AIVs) in live bird markets in 16 cities in Shandong province from 2013 to 2019. The predominant subtype was H9, and the newly sequenced H9N2 viruses were genetically similar. Several molecular markers associated with human adaptation, mammalian virulence, and drug resistance were identified.

Summary: During a 10-year period from 2010 to 2019, the circulation of influenza B viruses in Senegal was investigated. The study revealed a clear seasonal pattern of influenza B virus circulation in Senegal, with co-circulation of B/Victoria and B/Yamagata lineage viruses and reassortant viruses.

Summary: Beginning in late 2017, highly pathogenic avian influenza (HPAI) H5N6 viruses caused outbreaks in wild birds and poultry in several European countries. In Denmark, H5N6 viruses were detected in 43 wild birds found dead, with sequences closely related to contemporary HPAI H5N6 viruses in Europe, indicating multiple introductions. All viruses detected in the latter half of 2018 and 2019 grouped into the same cluster, suggesting viral maintenance in Denmark unnoticed during autumn 2018.

Summary: This study described the proportions, temporal and spatial distribution, and demographic and clinical characteristics of influenza A virus positive patients in Lahore, Pakistan. It identified distinct trends of ILI, SARI, and IAV positive cases, which can be used to inform public health interventions. Sampling from both ILI and SARI patients in routine surveillance is recommended.

Summary: This study investigates the presence of influenza and other respiratory viruses in older adults with influenza-like illness (ILI). It found that influenza virus was the most commonly detected virus, followed by rhinovirus, seasonal coronavirus, respiratory syncytial virus, and human metapneumovirus. Coinfections of influenza virus with other viruses were rare. The study also suggests that influenza virus infection may reduce the risk of simultaneous infection with other viruses. However, viral persistence or coinfections did not affect the clinical outcome of ILI.

Summary: This study investigated the outbreaks of H5N8 highly pathogenic avian influenza in Japan during the winter of 2020-2021 and found that the viruses may have emerged through reassortment events with Siberian avian influenza viruses. The study also revealed that H5N2 and H5N8 viruses isolated from wild birds in Siberia during the previous summer may have spread to both Asia and Europe in the following winter.

Summary: This paper presents the results of swIAV surveillance in Danish swine from 2011 to 2018, revealing multiple different circulating genotypes of the virus, including novel reassortants with human seasonal IAV gene segments. The phylogenetic analysis showed genetic drift in antigenic sites of the hemagglutinin protein and identified a swine divergent cluster among the viruses studied.

Summary: Surveillance of circulating avian influenza viruses in South Korea from 2009 to 2013 revealed predominantly low pathogenic strains among wild migratory birds, with no matches found for high pathogenicity strains. Regular surveillance studies are crucial to identify potential sources of influenza viruses that may threaten animal and human health.

Summary: This study provides a comprehensive virological and epidemiological overview of four influenza seasons in North Macedonia. Results show that sentinel surveillance system efficiently monitors influenza circulating in the region, with A(H1N1)pdm09, influenza B, and A(H3N2) being the predominant virus types.

Summary: Surveillance of swine influenza virus in Hanoi, Vietnam, from 2013 to 2019 revealed continuous enrichment and reassortment of virus lineages, with imported swine from Asia and North America playing a significant role. The introduction of human virus variants and swine influenza viruses endemic in other countries contributed to the diversity of H1 and H3 subtypes. The emergence of the North American H1-d1a strain with increased human adaptation poses a zoonotic threat, raising concerns for both human and animal health.

Summary: From 2018 to 2021, we identified 77 highly pathogenic avian influenza viruses in live poultry markets in northern provinces of Vietnam. These viruses belong to the H5N6 subtype and HA clades 2.3.4.4g and 2.3.4.4h. Interestingly, we did not detect viruses from clade 2.3.4.4b, which have been dominant in other parts of the world. The isolated viruses in Vietnam showed amino acid substitutions that may affect viral characteristics and could potentially reassort with other influenza viruses.

Summary: Antimicrobial resistance poses a threat to patient health, but data to optimize antimicrobial use are limited. By implementing lectures, publishing surveillance data, and presenting first-line treatments for community-acquired infections, the collaborative efforts have demonstrated the potential to optimize antimicrobial agent use and reduce the prevalence of antimicrobial resistance without compromising patient safety.
