  • ticks
  • What is alarming is that infections like WNV, spread by insects and ticks, are predicted to increase their distribution in the future, due to a number of factors that scientists are trying to understand i.e urbanisation, globalisation (one example being the spread of mosquito larvae with the tyre trade) and possibly climate change .
