Per оur clаss discussiоn, Rо is а stаtistical value calculated using three main factors. 1. infectious period 2. Mode of Transmission 3. Contact Rate. Using the following example, choose which of these three-factor(s) the researchers observed in their study that impacted the Ro in the following analysis. (Choose all that apply) Despite highly successful vaccination programs and high vaccine uptake, both endemic pertussis and periodic pertussis outbreaks continue to occur. The under-recognized role of adolescents and adults in disease transmission, due to waning immunity following natural infection and vaccination, and reduced likelihood of correct diagnosis, may contribute to pertussis persistence. We constructed a mathematical model to describe the transmission of pertussis in both pre-vaccine and vaccine eras, to estimate the underlying burden of pertussis in the population. The model was well calibrated using the best available data on pertussis in the pre-vaccination (1880–1929) and vaccination (1993–2004) eras. Best-fit model estimates gave a basic reproductive number of approximately 10.6, (seasonal range 9.9 to 11.5). Under-reporting increased with age, and approximately >95% of infections in children were caused by infections in persons with waning immunity to pertussis following prior infection or vaccination. A well-calibrated model suggests that under-recognized cases of pertussis in older individuals are likely to be an important driver of ongoing pertussis outbreaks in children. Model projections strongly support enhancement of booster vaccination efforts in adults. Pertussis Model ConstructionWe constructed an age-structured compartmental model that included births and deaths, and the introduction of the pertussis vaccine. Transmission of infection occurred through contact between susceptible or re-susceptible and infectious individuals. As individuals lost naturally-acquired or vaccine-induced immunity over time, they became re-susceptible to infection; we assumed that these individuals were equally susceptible as pertussis-naïve individuals, but were one-fifth as infectious (i.e., less likely to spread infection to others as assumed in previous models). This decrease in infectiousness incorporates both the hypothetical vaccine efficacy for infectiousness and the reduced duration of cough observed in partially immunized individuals.
A wife cоmes in tо mаke funerаl аrrangements fоr her husband. The wife expresses some concern about being able to pay the entire amount of the funeral. The wife’s sister, also present at the arrangement, tells the funeral director that she will guarantee payment if her sister is unable to pay. The wife signs the contract. 60 days later, the wife still has not paid. Can the funeral home sue the sister for payment?
