Right now, there are thousands of people still infected with Ebola. Right before the outbreak "ended," a new Ebola Makona strain was discovered. Long story short, if you are infected with specific Ebola Makona strains, you show no signs for years, but you can still spread it.
"Researchers will soon publish the first confirmed report of a person without obvious Ebola symptoms infecting another person."
Now, with the power of Lord Kek, Ebola-chan will be unstoppable.
