Measuring contact rates, mixing patterns and influenza transmission in schools
The importance of different routes on influenza transmission remain poorly understood. At least three modes are possible, including droplet transmission (coughing, sneezing), airborne transmission (fine aerosolized viral particles), and contact transmission (touch). Schools are thought to plat a major role in the spread of influenza, but little is known on how influenza spreads through such communities, severely hampering our ability to control influenza outbreaks.
Our aim with this study is to get a very detailed picture - for the first time - on exactly how influenza spreads in a high school using the following methods:
- Wireless sensor motes: to monitor close proximity interactions (CPI) of individuals in a high school community
- Short on-line contact surveys: to measure the error in subjective (survey) versus objective (mote) methods in collecting contact data
- Disease surveillance: by collecting nose-throat samples from individuals experiencing influenza-like illness (ILI) we will diagnosis influenza using RT-PCR. Positive samples will then be full genome sequenced.
