The migration of species due to STA can have a very prominent impact on human health when the species in question is able to carry and transmit disease. Anyamba et al. performed a study in which they studied the effects of SSTA and ENSO on the spread of two infectious diseases, Rift Valley Fever and chikungunya, which are carried by mosquitoes. The study found that climate variability related to STA and ENSO effects created “ideal ecological conditions for disease vectors to emerge”, and that under these conditions mosquitoes were able to infect people and livestock to a potentially epidemic level (Anyamba et al. 1). If incidences such as this one become more common as SSTA and ENSO weather patterns increase in frequency, “the potential for globalization of vectors and disease is likely to accelerate” (Anyamba et al. 1). Due to STA, diseases transmitted by vectors may potentially spread across the globe at a much faster rate which may have massive impacts on general public health and the economies of the countries that have to support the ill.
