“…Two highly pathogenic avian influenza virus (HPAIV) H5N1 strains, namely, A/HK/156/97 (clade 0) and A/DK/CAM/67F8/2008 (clade 1), were used for experiments performed in France and in Cambodia, respectively. Methods for the propagation of the A/PR/8/34 and A/HK/156/97 influenza viruses on MDCK cells were used in France to prepare inoculums, as previously described (21,43). In Cambodia, A/DK/CAM/67F8/2008 influenza virus stock was obtained after propagation in specific-pathogen-free (SPF) 9-to 11-day-old embryonated hen eggs, as previously described (12).…”

“…Infectivity of influenza H1N1 and H5N1 viruses was determined for experiments conducted in France by using a microtiter endpoint titration, as previously described (21). Infectivity was calculated by the Spearman and Karber method (14) and expressed as the 50% tissue culture infectious dose (TCID 50 ) per milliliter, as described in the European standard NF EN 14476 (1).…”

Contamination of lakes and ponds plays an essential role as a reservoir of avian influenza A virus (AIV) in the environment. A method to concentrate waterborne AIV is a prerequisite for the detection of virus present at low levels in water. The aim of this study was to develop and validate a method for the concentration and detection of infectious AIV from large volumes of surface water samples. Two filtration systems, glass wool and electropositive NanoCeram filter, were studied. The individual effects of filtration-elution and polyethylene glycol (PEG) concentration parameters on the recovery efficiency of the H1N1 strain from 10-liter surface water samples were assessed. An ultimate 1% recovery rate of infectious viruses was achieved with the optimal protocol, corresponding to filtration through glass wool, followed by a viral elution step and then a PEG concentration. This method was validated for the detection of highly pathogenic H5N1 strains from artificially contaminated larger water volumes, from 10 to up to 50 liters, from different sources. The viral recovery efficiencies ranged from 0.01% to 7.89% and from 3.63% to 13.79% with lake water and rainwater, respectively. A theoretical detection threshold of 2.25 ؋ 10 2 TCID 50 (50% tissue culture infectious dose) in the filtered volume was obtained for seeded lake waters by M gene reverse transcriptase PCR (RT-PCR). Moreover, the method was used successfully in field studies for the detection of naturally occurring influenza A viruses in lake water in France.

Introduction: SARS-CoV-2 RNA transmission in wastewater has a risk of fecal transmission ofSARS-CoV-2 to humans and the environment. Despite the increasing number of cases in almostall areas in Indonesia, the study to review and evaluate waste management resulted from medicalfacilities is still limited and less explored. This literature review aims to analyze the applicabilityof WHO guidelines on wastewater management to be implemented in Indonesia. Scientific paperswere collected from several electronic databases such as PubMed, PLoS, Researchgate, WHO,Elsevier, Science, SARS-CoV-2, Covid19, and wastewater. The articles were selected based on theinclusion criteria that use SARS-CoV-2, Covid19, and wastewater as the main variables observed.The articles published before 2013 were excluded from this review. Discussion: Wastewatermonitoring of SARS-CoV-2 within medical and health facilities is implemented to identify thevirus’s presence as the causative agent of Covid19 disease, which contaminated the environmentand society. The results of the analysis in wastewater can be used to determine the infectioncontrol in health facilities while also beneficial in formulating the monitoring of environmentalimpacts caused by the waste. These efforts would support policies or interventions based on publichealth by applying social distances, locking, quarantine areas that aim to break the Covid19transmission. Conclusion: Briefly, by considering the urgency of Covid19 pandemic containmentand control measures of transmission in health facilities, population and environment. It is a wastemanagement guideline that is highly required to be implemented based on public health aspects.

“…The most effective methods were ultraviolet irradiation at 25 mJ/ cm 2 , ozone at 0.5 mg/L e 1 mg/L/10mi,n and chlorine dioxide (0.3 to 3 mg/L (ppm)/5-120min), reducing >5log10 titers. Monochloroamine was the least efficient method (Lénès et al, 2010).…”

Avian influenza (AI) is considered an exotic disease in the Brazilian poultry industry, according to the National Avian Health Program (PNSA), with permanent monitoring of domestic, exotic and native avian species. Brazil presents privileged environmental conditions of reduced risk. In addition, all commercial poultry and conservation holdings are registered in state or national inventories and geographically located (GPS) for health control. Poultry health standards are adopted for the conformity to the international market, mostly for the intensified poultry destined for exportation, but also for companion exotic and native conservation facilities. Guidelines for monitoring and the diagnosis of AI are published by the PNSA and follow the standards proposed by the international health code (World Organization for Animal Health, Organization International des Epizooties - OIE) and insure the free of status for avian influenza virus (AIV) of LPAIV-low pathogenicity AIV and HPAIV-high pathogenicity AIV. In addition, the infections by mesogenic and velogenic Newcastle disease virus, Mycoplasma gallisepticum, M. synoviae and M. meleagridis, Salmonella enteric subspecies enterica serovar Gallinarum biovars Gallinarum and Pullorum are eradicated from reproduction. Controlled infections by S.enterica subspecies enterica serovars Enteritidis and Typhimurium are monitored for breeders. The vaccination of chickens in ovo or at hatch against Marek's disease is mandatory. Broiler production is an indoor activity, confinement which insures biosecurity, with safe distances from the potential AIV reservoir avian species. Worldwide HPAIV H5N1 notifications to the OIE, in March 2011, included 51 countries
