  1. aCalculated taking into account the assumed night time behaviour of the population
  2. Sample sizes (N) for indoor and outdoor collections combined are indicated. Percent contact indoors was calculated by dividing the HBR indoors (18:00–06:00) over the total HBR indoors (18:00–06:00) and outdoors (18:00–22:00). In addition, the entomological inoculation rates (EIR; number of infective bites per person per night) are shown. The November 2010 collection EIR was not included due to a loss of samples
