QMRA Introduction
During a 6-week period in 2003 in a long term care facility for elderly persons, 56 residents and 26 staff developed respiratory illness in a long-term facility; 12 residents died (Louie et al, 2005)
Hosts
Human
Transmission / Exposure Route
Aerosols of respiratory droplets and from contaminated surfaces, including direct person-to-person contact [1]
Case Fatality Ratio
During a 6-week period in 2003 in a long term care facility for elderly persons, 56 residents and 26 staff developed respiratory illness in a long-term facility; 12 residents died.[3]
Incubation Period
2-4 days [2]
Burden of Disease
Fifty-two percent (615/1192) of patients from October 2009 to December 2009 had a single respiratory virus and 207 had rhinobirus. [4]
Duration of infectiousness and disease

Asymptomatic Rates
Excretion Rates (see Exposure)
Immunity
Microbiology
Small (30 nm), nonenveloped viruses that contain a single-strand RNA genome within an icosahedral (20-sided) capsid. Rhinoviruses belong to the Picornaviridae family.[5]
Dose Response Models
Route: intranasal, Response: infection
beta-Poisson
$$P(response)=1-[1+dose\frac{2^{\frac{1}{a}}-1}{N^{50}} ]^{-a}$$
