Abstract Background: The avian influenza virus has different subtypes which have the potential to cause disease in animals and humans. Human cases with influenza A (H5N1), A (H5N6) and A (H7N9) viruses, have been reported to WHO and various influenza A (H5) subtypes continue to be detected in birds globally. Little is known about the types of exposure that result in human infections. In Ethiopia, risk assessment studies were not conducted and the awareness of the community and the risk of exposure for potential avian influenza is undetermined. The aim off this survey is to assess the level of the community awareness and the risk for human exposure to avian influenza viruses (HPAI) in the wet land areas of Ethiopia. Method: The survey was conducted from January 26 to February 28, 2018 in the wet land areas of Ethiopia by using a standard questionnaire and purposive random sampling method. Epi info version 7.0 and SPSS (V.20) were applied for data analysis. Result: Off the total 200 respondents 94.7% don’t know about the mode of transmission and 43.5%, 27%, 16.9% of the respondents believed that HAI it transmitted by inhalation of air droplet (breathing), contact with ill person and eating raw poultry meat and egg products. 36.2% of respondents believed that Human avian influenza is preventable by keeping hand hygiene, followed by respiratory hygiene (28%) and environmental hygiene (19.3%). However, 68.6% had close contact with animals (poultry) and high exposure to raw animal products. Conclusion: The awareness level of the community in the mode of transmission, risk factors and preventive measures is very low while the exposure for infected birds, food products remaining high. Further risk assessment studies and community awareness creation on the prevention and control of highly pathogenic avian influenza is recommended. Key words: Avian Influenza, Exposure, Ethiopia

Abstract Background Several outbreaks of highly pathogenic avian influenza (HPAI) caused by influenza A virus of subtype H5N8 have been reported in wild birds and poultry in Europe during autumn 2020. Norway is one of the few countries in Europe that had not previously detected HPAI virus, despite widespread active monitoring of both domestic and wild birds since 2005. Results We report detection of HPAI virus subtype H5N8 in a wild pink-footed goose (Anser brachyrhynchus), and several other geese, ducks and a gull, from south-western Norway in November and December 2020. Despite previous reports of low pathogenic avian influenza (LPAI), this constitutes the first detections of HPAI in Norway. Conclusions The mode of introduction is unclear, but a northward migration of infected geese or gulls from Denmark or the Netherlands during the autumn of 2020 is currently our main hypothesis for the introduction of HPAI to Norway. The presence of HPAI in wild birds constitutes a new, and ongoing, threat to the Norwegian poultry industry, and compliance with the improved biosecurity measures on poultry farms should therefore be ensured. [MK1]Finally, although HPAI of subtype H5N8 has been reported to have very low zoonotic potential, this is a reminder that HPAI with greater zoonotic potential in wild birds may pose a threat in the future. [MK1]Updated with a sentence emphasizing the risk HPAI pose to poultry farms, both in the Abstract and in the Conclusion-section in main text, as suggested by Reviewer 1 (#7).

Avian influenza A(H5) viruses (avian IAVs) pose a major threat to the economy and public health. We developed an antigen-ELISA (ag-ELISA) and a colloidal gold–based immunochromatographic strip for the rapid detection of avian A(H5) viruses. Both detection methods displayed no cross-reactivity with other viruses (e.g., other avian IAVs, infectious bursal disease virus, Newcastle disease virus, infectious bronchitis virus, avian paramyxovirus). The ag-ELISA was sensitive down to 0.5 hemagglutinin (HA) units/100 µL of avian A(H5) viruses and 7.5 ng/mL of purified H5 HA proteins. The immunochromatographic strip was sensitive down to 1 HA unit/100 µL of avian A(H5) viruses. Both detection methods exhibited good reproducibility with CVs < 10%. For 200 random poultry samples, the sensitivity and specificity of the ag-ELISA were 92.6% and 98.8%, respectively, and for test strips were 88.9% and 98.3%, respectively. Both detection methods displayed high specificity, sensitivity, and stability, making them suitable for rapid detection and field investigation of avian A(H5) viruses.
