The persistent non-pathogenic Nora virus common in Drosophila melanogaster provides a horizontally transmitted virus that students can research and design an experiment testing prophylaxis techniques for viral infection and pathogenic diseases. Students use inquiry-based methods to perform an experiment, analyze data, and draw conclusions on viral inactivation from disinfectant use on Nora virus in D. melanogaster.  \nKey words: viral infection, prophylaxis, transmission, Drosophila, disinfection, Nora virus  \nINTRODUCTION  \nInquiry based investigations are necessary to stimulate learning, understanding, and excitement of the scientific process in laboratory based courses. To engage students, selecting topics that are current and relevant is essential. One topic that is seemingly timeless and relevant to the student of any age is missing work or school due to preventable illness. Absenteeism from school and work associated with respiratory and gastrointestinal illness is costly and imposes a burden on education and family financial resources. Respiratory and gastrointestinal illness results from direct or indirect contact transmission of pathogenic viruses, bacteria, and fungi. Examples of these infectious respiratory viruses are respiratory syncytial virus (RSV), rhinovirus, and influenza, including the much-publicized H1N1 strain, avian, and swine influenzas (Goldmann, 2000; Centers for Disease Control and Prevention [CDC], 2012a) . Viruses causing gastroenteritis include norovirus, rotavirus, and adenovirus, with norovirus and rotavirus comprising the majority of United States infections responsible for up to 70,000 hospitalizations each year (CDC, 2012b; CDC, 2012c) .  \nHand hygiene in the form of hand washing with soap and water or hand rubbing with hand sanitizer is a well-documented prophylaxis for limiting indirect contact transmission of bacterial and viral infections, including both respiratory and gastrointestinal infections (Curtis & Cairncross, 2003; Rabie & Curtis, 2006; Sandora et al., 2008) . One study found that 37. 8% of rhinovirus remained viable after 1 hour on contaminated finger pads, and almost 16% after 3 hours (Ansari et al., 1991) . Rabie & Curtis (2006) found that hand washing reduces respiratory infection  \nby 16%, and Ryan et al. (2001) reported a 45% reduction in respiratory illness in outpatient visits asa result of proper hand washing implementation. Furthermore, the risk of diarrheal disease is reduced by almost 50% by washing hands with soap and water (Curtis & Cairncross, 2003) .  \nA less publicized way to control infection is fomite disinfection, as environmental surfaces become contaminated with pathogens by contact with nasopharyngeal secretions and contaminated hands. Fomites are inanimate objects, such as toilet seats or toys that can become contaminated. Rotavirus dried from fecal suspension remains viable for several days on fomites, and is readily transferrable from inanimate surfaces to hands and hands to surfaces (Ansari et al., 1988; Sattar et al., 1994) . Rhinovirus and RSV are transmissible from contaminated environmental surfaces between multiple people (Gwaltney & Hendley, 1982; Sattar et al., 1993) . In light of this, measures taken in preventing and controlling the spread of respiratory and gastrointestinal ill","cbCaibxdlo1EeKqv","https://ap.wps.com/l/cbCaibxdlo1EeKqv","pdf",161981,"English","# Abstract\n# Introduction\n## Preventable illness and absenteeism\n## Hand hygiene as prophylaxis\n## Fomite disinfection and environmental surfaces\n## Inquiry-based classroom laboratory investigation\n# Literature review and research question","[{\"question\":\"What teaching approach does the document describe for studying viral infection and prevention?\",\"answer\":\"It uses inquiry-based investigations where students research pathogens, design experiments, analyze data, and draw conclusions on viral inactivation after disinfectant use.\"},{\"question\":\"Why is Nora virus in Drosophila melanogaster suitable for student experiments?\",\"answer\":\"The virus is described as persistent and non-pathogenic to humans, and Drosophila melanogaster is a well-established laboratory model.\"},{\"question\":\"What control methods are emphasized for reducing viral spread?\",\"answer\":\"The document emphasizes hand hygiene (hand washing or sanitizer) and disinfection of environmental surfaces to address indirect contact transmission.\"}]","Nora Virus Transmission in Drosophila melanogaster - An Investigation to Teach Viral Infection and Prophylaxis to Biology Students | PDF",13]
