Taking action to break any link in the chain of infection—that is taking preventive measures—can stop the spread of influenza (see resources ).5,12 Resources: Influenza prevention Based on Chain Of Infection Link in Chain of Infection Influenza implications Notes for pharmacy staff Infectious agent Present. Toothbrushes, razors) remind all household members to use disposable tissues, cover their mouths when sneezing or blowing their noses, and wash their hands immediately afterward. Ensure infected family members have trash cans nearby to dispose of tissues and wipes; educate each household member to avoid placing soiled tissues on the ground or nearby surfaces remind people to keep their hands away from the face and mouth. Transmission Organism can remain active on environmental surfaces remind patients to disinfect objects and surfaces such as telephones, computer keyboards, light switches, door knobs, remotes, and children's toys The Environmental Protection Agency only allows manufacturers to use words like "sanitize" or "disinfect" on products that. The most commonly used products are pine sol, Clorox, and Lysol Lemon juice, lavender, and tea tree oil or natural products that have disinfectant properties A mixture of 1/4 cup chlorine bleach to 1 gallon hot water will also disinfect Consider using washing machine. If soap is unavailable, alcohol-based hand rubs with at least 60 alcohol are recommended evidence that facemasks prevent influenza transmission is lacking but cdc recommends facemasks when healthcare personnel enter a room belonging to a patient with suspected or confirmed influenza patients with suspected influenza.

Cdc recommends annual vaccination against seasonal influenza for everyone starting at 6 months of age.10 Despite early speculation that the current flu vaccine had low effectiveness, cdc released updated data on February 16, 2018. It indicates that between november 2, 2017 and February 3, 2018, the overall adjusted vaccine effectiveness against influenza a and influenza b virus infection was. Influenza a(H3N2) viruses caused 69 of influenza infections, and the vaccine's effectiveness was approximately. Its effectiveness was 67 and 42 against influenza a (H1N1)pdm09 and influenza b viruses, respectively.11. This stands repeating: The best way to protect oneself from the flu is to receive an annual flu shot.10,11. Transmission, viral disease results from specific interactions between the virus, susceptible host, and environment, a process called the chain of infection.8 Influenza viruses spread by droplet infection (exhalation, coughing, sneezing, etc).5,8. If virus-containing droplets reach others' mucous membranes, recipients may develop the flu. Virus- containing droplets may also land on an intermediate surface where they can survive store for 24 hours.5,12 If individuals aiou inhale the virus or touch a contaminated surface and self-inoculate themselves by touching their noses, eyes, or mouths, they may develop symptoms 1 to 4 days. Sick adults are contagious beginning 1 day before symptoms appear, peaking on the first day of clinical illness, and for 5 to 7 days after symptoms develop. Children and immunocompromised individuals can be contagious for longer. Patients are most contagious within 3 days of illness onset.12.
Precipitates a need for a new vaccine entirely. Often associated with epidemic or pandemic. Source: Reference 5,8, seasonal Vaccine, due to the mercerial nature of the virus a need is created to predict which strains will circulate in the next flu season. This need is filled by the world health Organization (who which monitors viral changes globally. Each year, the who global Influenza surveillance and Response system chooses 3 strains for inclusion in the next year's flu vaccination. They biography select the H1N1, H3N2, and Type-b strains thought most likely to cause significant human suffering in the coming season. Starting with the northern Hemisphere influenza season, who has also recommended a second B-strain for use in quadrivalent vaccines.9.
An example of antigenic shift might be when an avian virus and a human virus simultaneously infect a cell in another species, for example a pig. This creates the potential for their genetic business materials to be mixed creating a new and hybrid-type virus with gps increased virulence in humans.8. Antigenic Shift and Antigenic Drift. Antigenic drift, antigenic shift, a predictable slow accumulation of multiple small mutations in hemagglutinin (H) and neuraminidase (N) genes. Occurs in all types of influenza. May lead to a loss of immunity or vaccine mismatch. Precipitates the need for annual vaccination with predicted circulating strains. Rarely associated with pandemic, an unexpected event in which at least two different viral strains or viruses from different species combine to form a new subtype. Occurs only in influenza a viruses.
Various influenza a viruses have different hemagglutinin and neuraminidase subtypes, with hemagglutinin occurring as types H1 through H18 and neuraminidase occurring as types N1 through N11. The circulating virus's nomenclature incorporates these designators, and currently influenza a (H1N1) and influenza a (H3N2) viruses are problematic.5,7. Type b viruses, which are unique to humans, tend to cause milder influenza than type a, and primarily infect children. They are more stable than influenza a, and are differentiated not by subtypes, but by lineages and strains. Currently, the circulating influenza b viruses belong to one of two lineages: B/Yamagata or B/Victoria.5. Although, type c viruses infect humans and pigs, they are relatively uncommon and most cases are mild and asymptomatic. Type d influenza viruses affect cattle primarily, not humans.5. Antigen Drift and Shift, influenza viruses change constantly using 2 mechanisms: antigenic drift and antigenic shift (see. Antigenic drift is expected; health policy makers anticipate antigenic drift and plan for.5,8 Antigenic shift is a much more serious development, and leads to new and potentially more virulent viruses.

All indicators suggest flu activity will be as high as or higher than the season, which public health officials determined to be a high severity A(H3N2)-predominant season.6. Influenza viruses, pharmacists field many questions from patients and hear many comments. This year, many patients wonder why the flu shot doesn't appear to be is as effective as it could be, and why they need annual influenza immunizations. Pharmacists and pharmacy technicians need a basic understanding of influenza viruses to address these concerns appropriately. Influenza viruses are rna viruses belonging the.
Influenza viruses come in four types a, b, c, and d with human influenza viruses a and B responsible for seasonal influenza epidemics that occur almost every winter master's (although flu infection is possible year-round). In general, influenza a virus are usually responsible for influenza pandemics.5. Type a viruses are the most virulent, producing the most severe symptoms. They infect humans and many different animals (e.g. Cats, chickens, ducks, horses, pigs, georgia seals, whales). Influenza a's 2 surface glycoprotein antigens, hemagglutinin (H) and neuraminidase (n explain its virulence. The h antigen allows the virus to enter cells, and the n antigen facilitates cell-to-cell transmission.
Modest estimates indicate that 50 million people or more died from the. Spanish flu, so- called because Spain, a neutral country during World War i, did not censor the news and reported openly about widespread influenza.2 Allied and central power nations did not, believing that public discussion of an influenza pandemic would quash morale. People in nations that had media block outs obtained most of their information from Spanish news media outlets, and dubbed this flu "Spanish flu." (The Spaniards, however, called it "French Flu. Researchers did not isolate actual viral particles until the 1930s, with influenza a virus isolated from ferrets in 1933, and influenza b virus in 1936. This led to the discovery that culturing the virus in fertilized hens' eggs diminished its virulence, and eventually the development of inactivated vaccines in the 1950s.5. Vaccination became and continues to be the most effective way to limit spread of influenza, but has not eliminated periodic pandemics.5 Since the influenza vaccination's introduction, several global epidemics have occurred.
These include a 1957 Asian flu pandemic that killed approximately.5 million people, a 1968 pandemic of Hong Kong flu that killed 1 million, and a 2009 pandemic of swine flu resulting in approximately 575,000 deaths. In the 2009 epidemic, a new influenza a (H1N1) virus emerged that was very different from previous circulating human influenza a (H1N1) viruses. The new virus has now replaced earlier H1N1 subtype that infected humans. (cdc, 2017a) (cdc, 2016b who, 2017).5. In the current epidemic, activity began to increase in early november 2017 and remains elevated at this time (February 2018). Patients most often have influenza a(H3N2) viruses, but A(H1N1)pdm09 and b viruses are also circulating.
