Avian grippe - Essay ExampleThe swine flu epidemic of 2009 made things look worse. Efforts since then had been consistently attempting to be ever-ready for an influenza epidemic through improving global surveillance and response capacity. The H5N1 avian flu computer virus was highly pathogenic and had caused infirmity widely in wild birds and poultry (CDC, 2009). It caused 408 human cases by February 2009. Guidance for testing of suspected human cases infected with pathological avian flu with H5N1 influenza virus were provided. Enhanced surveillance by local and national health care services was to continue. Cases were to be notified to the local and national authorities immediately a presumptive diagnosis is made. Follow-up of cases was a necessity. In the US, information had to be transferred to the CDC (CDC, 2009). Guidelines for diagnosis Testing and reporting guidelines had been established by the CDC. A person diagnosed presumably with avian flu had to be hospitalized becaus e it could end fatally. Another requirement for hospitalization was that the temperature of the patient would be equal to or more than 38C. The patient could defy any other respiratory illness like pneumonia or acute or severe respiratory illness (CDC, 2009). ... The infection was spread through droplet infection when in close contact. Procedure for diagnosis Clinicians needed to notify the local and higher authorities when a person was to be diagnosed using laboratory tests. precise guidelines were also followed for the clinicians who performed the specimen collection and testing. Protective equipment for the clinicians was to be strictly used to prevent any contamination of the body parts with the suspected or corroborate person with H5N1 virus and when entering the room where aerosol generating procedures have been used where such a patient was lying in (CDC, 2009). The respiratory protector (N-95) filtering brass mask, goggles, face shield, latex gloves, gown and head cover ing were all included (CDC, 2009). In the absence of a particulate respirator, other certified respirators like the NIOSH-certified N-, R-, or P-class respirators could be used. The aerosol-generating procedures could be done only with the N-95 respirator or powered air purifying respirators (CDC, 2009). Bronchoalveolar lavage was a high-risk aerosol generating procedure which required refined protection. If the clinician had a beard, a loose-fitting respirator could be used. The virus could be detected from the bronchoalveolar lavage, oropharyngeal pats, or endotracheal aspirate as these specimens usually had the virus. The nasopharyngeal swab contained lesser virus so lower respiratory specimen should be taken (CDC, 2009). However nasopharyngeal swabs sufficed for detection of influenza viruses A and B. If most virus count needed to be isolated, multiple respiratory specimens from the same patient could be taken on other days too. The
