IN FACT, THERE ARE ONLY TWO WAYS TO LIMIT THE SPREAD OF INFECTIOUS DISEASES FOR WHICH THERE IS NO MEDICAL TREATMENT, NO ANTIBIOTIC OR NO ANTIVIRAL OR NO VACCINE:
SANITATION AND QUARANTINE.
THERE'S EVEN BEEN A QUARANTINE FLAG FOR SHIPS FOR CENTURIES: WIKI:
In International maritime signal flags, plain yellow, green, and even black flags have been used to symbolize disease in both ships and ports, with the color yellow having a longer historical precedent, as a color of marking for houses of infection, previous to its use as a maritime marking color for disease.
The present flag used for the purpose is the "Lima" (L) flag, which is a mixture of yellow and black flags previously used. It is sometimes called the "yellow jack" but this was also a name for yellow fever, which probably derives its common name from the flag, not the color of the victims (cholera ships also used a yellow flag).PERHAPS WE COULD USE A NEW FLAG FOR EBOLA.
