Usage examples of exposure.

Cockle sang two songs without accompaniment, for he was not willing to risk either his hands or his instruments by exposure to the chilling wind.

In order to avoid chill and exposure, he was operated on in his old clothes, and while one limb was being amputated the other was being prepared.

Every hybridizer knows how unfavourable exposure to wet is to the fertilisation of a flower, yet what a multitude of flowers have their anthers and stigmas fully exposed to the weather!

I returned to Washington that afternoon and was asked by Senate Republican leader Trent Lott to be the liaison for the Republican senators to the fledgling medical and law enforcement investigation into the anthrax exposure at the Hart building.

Nasal swabs to determine how widespread exposure to the anthrax spores had been were eventually obtained from everyone in the Hart building.

When nasal swab test results confirmed the direct exposure to anthrax of twenty-eight people inside or immediately adjacent to the Daschle suite, anxiety across Capitol Hill soared.

As thousands of Senate and House staff and those who had been visiting Senate buildings on Monday lined up for their nasal swabs and three-day Cipro supply, my staff busily printed out information on anthrax exposure that we gathered from my Senate website and others and handed it out to those who waited in line.

During the meeting, I briefly addressed my colleagues, offering my views from a medical standpoint on the anthrax exposure so far.

But equally important, these press conferences gave all of us the opportunity to establish who the public health command team was and to explain to the public what anthrax is, what the relative risk of exposure is, what Cipro is and what its side effects are, how anthrax is treated, and what the difference is between nasal swabs that measure exposure and other tests that measure disease.

If fitted correctly--and this is harder than it sounds--respirators can reduce exposure to anthrax bacteria and other harmful agents.

In the inhalational anthrax cases following September 11, the average time from exposure to the bacteria to the onset of symptoms was four days.

But experts believe that illness may occur as long as sixty days after exposure to anthrax spores, because observations have shown that the spores can take that long to change to active bacteria.

This type of exposure leads to gastrointestinal anthrax, which usually has an incubation period of two to five days.

Assume you have the flu unless: Anthrax exposure or cases are reported in your community.
