Not like extra generally encountered strains of the virus, there aren’t any authorized vaccines or drug remedies for Bundibugyo, although some experimental choices exist.
Customary diagnostic testing has confirmed unreliable in figuring out this pressure, early samples returned damaging outcomes, and solely after extra superior evaluation might scientists verify that Bundibugyo was accountable.
