Man, thats not a flu, at least not what I undestand about flu. Maybe the flu and the "strong flu" have the same name in english ;x I apologize if thats the case.
Btw...
"Weak Flu"[en] = Resfriado[pt] = Annoying sneezes.
Flu[en] = Gripe[pt] = Annoying sneezes, cough and lil feeling of "I dont wanna eat"
"Strong Flu"[en] = Virose[pt] = Strong flu, have many variations. Fever, Muscle pain, Diarrhe, Vomiting... or any combination of things above.
If all of you devs with gimped immunity armor got the strong flu, then <3 get better!
EDIT: @SultryVoltron They prolly got the flu inside the airplane.
