verruga

"All residents should evacuate the margins of the River Verruga urgently," it added.

Yaws, yaws, n. a tropical epidemic and contagious disease of the skin—also Frambœsia, Button scurvy, Verruga Peruviana, Buba or Boba, Patta, Tetia, &c.—adj.

Scientists first heard of verruga in 1870, during the building of the Central Railway, when 7,000 workers died before the rails had been pushed out of the valley.

Doctors have found no effective treatment for verruga.

The natives appear to survive mainly because those who live through a mild form of verruga in childhood develop immunity.
