virus

Foot and mouth disease is a highly infectious virus which causes blisters inside an animal's mouth and under their hooves, and can cause lameness and problems feeding.

Instead, even after decades of incremental improvement, this crisis of violence against women and girls continues to spread like a virus and and even thrive because as a society we refuse to wipe it out.

Prior to the introduction of the measles vaccine in 1963, the virus killed about 500 Americans and disabled about 1,000 every year.

This epidemic, caused by a virus that was once eliminated in the U.S. in 2000, has claimed at least two lives: two children, one eight-years old and the other only six.

That means the virus is likely to circulate for a while in western Texas regions where people are unvaccinated, officials said.
