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

Symptomology

Latency

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

$$P(response)=1-[1+dose\frac{2^{\frac{1}{a}}-1}{N^{50}} ]^{-a}$$

Optimized parameters:
a = 2.21E-01
N50 = 1.81E+00
ID50 = 1.81E+00
