Uncontrollable spread of infections

The authors published their findings in the journal Philosophical Transactions of the Royal Society B, and they were also summarized by The Daily Mail.

Previously, scientists believed that in order for parasites to adapt to a new host body, they need a long time. Scientists believed that the adaptation to change might take about a hundred years.

A new study by specialists shows that parasites are able to adapt to new conditions much faster, and global warming only contributes to that.

In their work, the researchers observed changes in habitats of some parasites both in tropical regions of the earth, and in the cold Arctic. Thus, for example, the scientists have recorded the spread of some parasitic roundworms (nematodes) from southern regions to the north, where these animals have found new hosts (muskox in northern Canada).

According to scientists, the observed changes have occurred in the last 30 years. Experts made a conclusion in their study that people may not be able to manage the high speed of the spread of parasites and other harmful organisms.

As an example, they refer to Ebola, the distribution of which is largely restricted by regional climate features of other (non-African) regions of the Earth. In case that climate changes will occur to quickly, it will become increasingly difficult to stop the spread of new diseases, the researchers note.
