23 Tiredness Headache Fever & Chills Influenza Symptoms Body Aches Chest Discomfort

24 Flu Prevention Get vaccinated!  Your best protection! Practice good hygiene  Wash hands often  Cover your mouth/nose when you cough/sneeze  Put used tissues in waste basket  Clean your hands after you cough/sneeze  Avoid touching your face, eyes, nose or mouth If you are diagnosed with the flu  Stay home  Avoid close contact with others, or wear a mask  Get rest and drink plenty of fluids

26   Transmission   Respiratory route   Direct contact   Communicability – 1 to 2 days pre-onset to, 4 to 5 days post-onset   Reservoir   Humans, swine (H1N1), and birds (H5N1)   Geographic distribution   Global   Incubation   1 to 5 days; usually 2 days Influenza Virus

27 Nosocomial Influenza  Transmission that occurs in a healthcare setting  Can result from under-vaccinated healthcare personnel

28 In a tertiary care facility from 1987 to 2000:  Staff influenza vaccination coverage  4% >>> 67%  Staff influenza disease  42% >>> 9%  Nosocomial Disease  32% >>> 0 cases Salgado CD, Infection Control Hospital Epidemiology, 2004 Nosocomial Influenza

29 Influenza in the Elderly Kimura, et al. American Journal of Public Health, 2007 The elderly have suboptimal immunologic response to the flu vaccine.   80% effective in preventing death   27% to 70% effective in preventing hospitalizations and pneumonia   30% to 58% effective in preventing flu The flu shot is about… Despite high vaccination rates among residents, influenza outbreaks still occur in LTCFs, triggered by unvaccinated HCP.

30 Influenza in LTCF  Influenza Attack Rates 25-60%  Case-fatality 10-20% Randomized control study  Staff vaccination led to a 43% decrease in ILI  44% decrease in mortality Potter J, et. Al. J Infectious Disease 1997

31   Children between 6 months and 18 years of age  Healthcare personnel (HCP)   Persons > 50 years   Nursing home & chronic care residents with chronic medical conditions   Persons with chronic pulmonary or cardiovascular disorders, including asthmatic children   Pregnant women   Persons with immunosuppression including HIV Who’s at Risk?

32 Facts vs. Myths  I get sick from the vaccine Myth The influenza vaccine is made from a DEAD virus  You cannot get sick from it  Side effects may include a low-grade fever and muscle aches  The flu shot can take up to two weeks to become effective so you can still get the flu or a flu-like illness during this time

33 Why I didn’t get a flu shot…  My doctor didn’t recommend it  I am afraid of needles The flu shot is given with a relatively small needle. Check with your doctor to see if you are eligible to receive FluMist® - a vaccine that is sprayed into your nose and does not require needles.  The Flu isn’t that bad Influenza causes an average of 36,000 deaths and over 200,000 hospitalizations per year.

34 Shot vs. Nasal Spray Flu Shot (TIV)  Injectable – Trivalent inactivated influenza vaccine  70-90% effective in healthy persons ≤65 yrs  50-60% effective in preventing hospitalization  80% effective in preventing death  Few side effects (sore arm, general malaise) Nasal Spray (LAIV) - FluMist®  Live attenuated influenza vaccine  No needles – spray mist into the nose  Approved for healthy persons ages 2-49 years of age  Slightly more expensive

35 Novel H1N1 Vaccine Who should receive the vaccine? EMS and HCP Pregnant women Caregivers of <6 months 6 mon – 24 yrs, 25 – 64 yrs w/ underling chronic conditions Now open to everyone Where can I get it? Your physicians office Local PHC, Mass Vax Clinics How many doses will I need? Only one dose for 10 yrs and older How much will it cost? Free – Feds paid for all doses Nominal administration fee How safe is the vaccine? Extremely safe! It is made using the same processes & facilities as the seasonal flu vaccine. It is very much like the seasonal flu vaccine. Should I get the vaccine if I think I’ve already been infected? Yes, the flu symptoms you had may not have been caused by the H1N1 virus.

36 also know as “Whooping Cough” is a highly contagious bacterial infection of the lining and airways of the respiratory tract. It is caused by the bacterium Bordetella pertussis. PertussisPertussis

40 Clinical Signs of Pertussis  Cough 97%  3 weeks, 52%  9 weeks  Paroxysms 73%  3 weeks  Whoop in 69%  Post-tussive emesis in 65% De Serres et al. J Infect Dis. 2000;182:174–9.   Teens missed average 5 days of school   Adults missed average 7 days of work   Average 14 days of disrupted sleep

41 3 Stages of Pertussis C atarrhal RRunny nose, sneezing, low-grade fever, and a mild, nonproductive, occasional cough MMost infectious during the this period and the first 2 weeks after cough onset (approximately 21 days) P aroxysmal SSevere spasms of quick, short, coughs MMay gag, gasp and/or expel thick mucus ““whoop” FFollowing attack VVVVomiting and exhaustion

42 Convalescent  Gradual recovery  Cough frequency decreases  Cough severity decreases  Recovery may be only partial Source: 3 Stages of Pertussis

43 How is it diagnosed?  Multiple tests may be required to accurately diagnose disease  Frequent incorrect diagnoses:  Asthma  Gastroesophageal reflux  Post-viral bronchospasm  Chronic sinusitis  Tuberculosis

44 Culture and PCR   Nasopharyngeal (Dacron) swab or aspirate is the preferred sample   It’s the nasopharynx we’re after

45 Pertussis in Adults Adults Adults:  Are the main reservoirs of disease in areas with high immunization coverage rates  Transmit primarily to non-immune children (≤ 1 year of age) or to adults whose immunity has waned (median 93 days)  Experience the longest recovery time (median 93 days)

48 n=264 cases Infant Pertussis: Who Was the Source?. Bisgard, K. PIDJ. 2004;23:985-9.

49 Costs of an Outbreak  September 2003 – outbreak of pertussis in an acute care facility  17 employees were infected  Following a one-day exposure to an infant with pertussis  Infection control measures were immediately implemented in hospital  Study examined outbreak-related costs and estimated possible benefits to vaccination

50 Study Results  Cost incurred by the hospital:  Cost incurred by the employees:  TOTAL COST incurred:  Cost of 1 dose of Tdap: $74,870 $6,512 $81,382 $37.00 $37.00

51 Estimated Benefits of Vaccination  Study model predicts:  Vaccinating employees in hospital against pertussis would prevent ≥ 46% of exposures  Cost of vaccination to benefit ratio is 2.38 : 1

52 CDC Recommends  All HCP in hospitals, LTCF/SNF, ambulatory care and emergency medical services (EMS) settings also receive Tdap in place of Td booster  Priority groups:  HCP in contact with infants less than 12 months  Emergency Departments  Maternal/Child Health  ICU/NICU  Respiratory Therapy

53  All adults receive Tdap in place of their tetanus booster  Postpartum mothers and/or primary caregivers receive Tdap CDC Recommends

54 Tdap Vaccine  Tetanus diphtheria acellular pertussis  Licensed in 2005  Only one dose is required and it c an be given in an interval as short as 2 years from the last Td booster

55 Tdap Adverse Reactions  Localized pain, redness, swelling  Low-grade fever  Adverse reactions occur at approximately the same rate as Td alone Source: CDC Pertussis Information

56 A True Story…

57 Conclusions  Vaccinating ADULTS with Tdap:  85% protection with vaccine!  Protect your family from pertussis  Prevent an outbreak in workplace thereby reducing costs and minimizing sick leave  Keeping adults up to date with their vaccines can minimize the effects of vaccine-preventable diseases
