The CDC says it's developed a new rapid rabies test. Federal health officials say it could mean that people potentially exposed to rabid animals could skip the weeks-long regimen of shots to prevent the deadly disease. The L-N-34 test was designed for use in animals and is easier and more precise than current rabies tests. The CDC says a pilot study showed it produced no false negatives and fewer false positives. The use of the technology makes it easier for doctors to decide who needs to be treated for rabies. The virus is almost always fatal if allowed to develop.
