> There are species of Plasmodium which survive on non-human hosts which means the disease will always be waiting A small correction, the species you're referring to don't 'survive' in non-human hosts, but actually the other way around. There are probably thousands of plasmodium species that infect everything from lizards to birds to monkeys. In monkeys (eg simian) there are a large number of pasmodium species that have undergone zoonotic transfer thereby infecting humans. It's believed the 'last man standing' in defeating malaria will be P. Knowlesi, or monkey malaria. It can infect humans, and seems to be quiet common in Borneo Island. But it hasn't to my knowledge, started transmitting human to human. But without a doubt we will continually see spill-over events of not only Malaria but other parasites.
