Influenza Virus Prevention

680 Words2 Pages

Influenza is caused by an RNA virus from the Orthomyxoviridae family (that consists of the genera influenza A, B, and C). Human influenza A and B viruses cause seasonal epidemics almost each winter within the United States. Influenza type B infects humans only, therefore it is unable of undergoing a mutation. Pandemics are caused solely by influenza A strains. The emergence of a new and completely different influenza virus to infect people will cause an influenza pandemic. Influenza kind C infections cause a mild respiratory illness and aren't thought to cause epidemics (Duncan, 2013).
The influenza virus is transmitted from human to human mainly by droplet, although there are cases of animal to human transmission. The incubation amount is approximately 3 days, although nasal shedding can peak about 24-48 hours once onset of symptoms. Viral shedding starts at intervals 24 hours before the onset of symptoms and continues for up to five days in healthy adults and a number of weeks in immunocompromised patients (Duncan, 2013). It has been shown that both influenza A and influenza B viruses can survive for 24-48 hours on nonporous surfaces like chrome steel. They can survive for 8-12 hours on products like tissues. Prevention should focus on: hand-washing, avoidance of touching eyes and different mucous membranes, cleaning commonly used surfaces, and by covering the mouth and nose when coughing or sneezing (Duncan, 2013).
The most known groups at risk are: elderly individuals (over 65), pregnant women, patient with chronic cardiac, pulmonary, renal, hepatic and neurological disease and diabetics. The common symptoms of influenza are: fever or feeling feverish/chills, a temperature of 38°C (100.4 °F) or above, cough, sore th...

...d receive antiviral treatment immediately while waiting for test results (Unknown, 2013).
Influenza can be introduced and spread into an extended-care facility by newly admitted residents, health care staff and by visitors. Residents of long-term care facilities may experience severe and fatal illness during influenza outbreaks. Preventing transmission of influenza viruses and different infectious agents inside health care settings, needs a comprehensive approach that includes: vaccination, testing, infection management, and antiviral treatment (Unknown, 2013).
Management of patients in the high risk groups requires early diagnosis and treatment with antivirals. The best course of treatment is prevention of the disease through vaccination and education. Annual influenza vaccination is the first step for preventing influenza and its complications (unknown, 2013).
