Disease increase due to global warming?

Question

Hi! I'm doing a project on global warming and I want to know, why is there an increase in diseases like malaira andwest-nile virus. I know it has something to do with climate change...but I can't find the answer. Please include where you got your information! THANKS!

Answer 1

yes it is due to g.w. I study it and so i would know

Answer 2

It goes something like this: As global climate changes occur, there will be an increase in habitat suitable for pest species like mosquitoes and ticks.  So associated diseases such as West Nile and Malaria are expected to increase in some areas.

Answer 3

you don't need opinions & inaccurate computer projections. just compare the different health problems & disease rates between people who live in new york & people who live in florida.

you will find people who live in warmer climates with  the same economic system & income are healthier.

the difference among the lower income groups is even more pronounced.

the climate differences between the two states are more than hundreds  of  years of projected worst case global warming.

Answer 4

Have you googled these two diseases yet? If not I suggest you do that. I'm sure you'll get plenty of information about how these diseases are spread and what type of climate the host needs to thrive.

Answer 5

It's indicative to CC and not an absolute, IPCC forewarns that's it's only circumstantial. You first have to understand what is the genetic characteristics of each pathogen, virus, and what their requirements are. There's a predominate factor all have in common ie; antigenic variations. Plasmodium Falciparum(malaria) falls into this grouping. The only exclusion I know of is African swine fever which is a vector borne virus. The mechanism of virus are different, but also can undergo diversity between strains/gene displacement. This is one reason pathogens and virus have a bad reputation. It doesn't mean because you've been bitten that you will succumb to the disease. It depends on the amounts of pathogens and viral load. The body also has natural defenses, at least ten or more variants of serotyping can occur during infection. Yes climate does have an influence but it's not considered to be the only focal point. It's normally associated with poor hygiene, lack of medical care/drugs, and water quality in poorer countries. They haven't had much success with predictability, but be assured it will happen.
