Some models predict large changes in rainfall patterns, while other predict small changes. We may expect with increases in rainfall there would be an increase in mosquito numbers and a subsequent increase in mosquito-borne diseases, however this may not be the case. The biology of mosquito-borne diseases is a very complex issue and involves the mosquito vector, reservoir hosts and even sociological factors. All we can be certain of, with global warming, is that there will be a change in the amount and distribution of disease, but to what extent, it is not known. There is some debate as to the presence of Lyme disease in Australia.
Some workers believe that it is here.
If Lyme Disease is present in Australia, then that it must be very rare. When a tick is removed, commonly a portion of the head or the mouthparts are left behind. Generally this does not cause any problems as the head of the tick will fall out as the skin sloughs off in time. However, if a local reaction does occur, then a physician should be consulted. No, this often causes the tick to inject its saliva into the host and can increase the risk of transmitting disease causing organisms, or increase the risk of death from paralysis.
