What two things threatened to get rid of malaria forever?

The two significant threats to eradicating malaria forever are the development of drug resistance in the malaria parasite and insecticide resistance in mosquito vectors. As malaria parasites evolve to resist treatments like artemisinin, and mosquitoes become resistant to commonly used insecticides, control efforts become increasingly challenging. Additionally, socio-economic factors and climate change can exacerbate the spread of malaria, complicating eradication efforts. Together, these challenges hinder progress toward a malaria-free world.
