R code and data

Surveillance for viral respiratory illnesses, Respiratory syncytial virus (RSV) was implemented in Dadaab refugee camp in north eastern Kenya in 2007. Paediatric and adult patients who presented at a camp medical unit, and met the case definition for influenza-like illness (ILI) or severe acute respiratory infection (SARI), were enrolled into the laboratory-enhanced respiratory surveillance system and tested for all of the above disease after an informed consent form was completed by adults, older minors, and guardians of all minors <15 years. The monthly counts of all RSV cases among children younger than 5 years were included in the present analysis; the main outcome of interest being monthly RSV incidence rate in this age group. Local weather and climatic data, including: the mean temperature and mean dew point for the day (both in ⁰F); mean sea level pressure for the day in millibars; mean visibility for the day in miles; mean wind speed for the day in knots; minimum and maximum temperature (⁰F) reported during the day; and the total precipitation (in inches) reported during the day were obtained from the World Meteorological Organization’s (WMO’s), World Weather Watch Program, according to WMO Resolution 40 (Cg-XII) (available at http://www7.ncdc.noaa.gov/CDO/cdo).
