An
infected cow's brain, spinal cord, and other nervous-system tissues can carry the disease.
Furthermore, some strains that use CXCR4 only, such as UG021, could also
infect macrophages through the CXCR4 co-receptor.
In West Africa, for example, Lassa virus
infects 100,000 to 300,000 people per year, killing more than 5,000 annually.
Caffrey adds that it's risky to rely on a single drug against a parasite that

They usually
infect executable files with these extensions: *.COM, *.EXE, *.DRV, *.DLL, *.BIN, *.OVL and *.SYS.
It's not a problem unless it can jump from one species to another." And that's precisely what happened in Britain, where a cow-based TSE known as Bovine Spongiform Encephalopathy (BSE), jumped to humans who came in contact with affected cows or ate
infected meat.
