"Is the cholera bacterium really that hard to eliminate?"
"Throughout history, cholera has always been an infectious disease with a very high mortality rate. Even with the advanced medicine we had before the apocalypse, we could never completely eradicate it. And now, we're living in the apocalypse."
Ethan Dawson's expression turned serious. "If cholera can appear, other infectious diseases might show up too. The plague, avian flu, yellow fever, influenza, echinococcosis, filariasis, dengue fever, malaria, Ebola, schistosomiasis, typhoid fever, Hepatitis A, Hepatitis B, AIDS…"
After hearing Ethan Dawson's impromptu lesson, everyone's faces changed.
"I can't believe there are so many infectious diseases in the world. That's terrifying."
"That's not all. I only listed the ones I know. We still have to be careful. Under the long night, new types of bacteria and viruses that have never been seen before could emerge."
