If alternative, safe sources of nutrition can be made practically and reliably available, people should simply stop eating bats and primates. This is not the voice of conservation speaking here;
it's the voice of public health and common sense.
Knowing that bats are uniquely positioned in the animal kingdom as veritable virus factories, we need to know where people rely on access to bats as a food source. There are such places in the world, but there are likely as many if not more locales where bats are a preferred food, but not an essential one.
It's important to note that the current Ebola outbreak
appears to have originated when a 2-year-old child either touched a captured bat or consumed meat from one.
Bats seem to be a
unique source of zoonotic viruses (viruses transmissible from animals to people) -- from SARS and Ebola to Nipah and rabies -- just to name a few. Because of this we should work to discourage the capture, killing and consumption of bats, the disruption of their roosting trees, and the establishment of farms right where they defecate and urinate.
The same can be said for primates, our closest relatives. We share a lot of diseases with them, and indeed we know that HIV/AIDS arose from the butchering and consumption of chimpanzees. If we can make sure those in need of nutrition can get it in other ways, humanity would be much better off not eating primates of any kind.
