For a moment I had an impulse to cross the line she had set for me, to go as she had gone into infected places.

But more and more infections found ways to cross the border.

If this hypothesis is true, early exposure to childcare outside the home would protect against atopy by promotion of cross infections.
The Airsonett Airshower® air purification system minimizes cross contamination of germs and bacteria, and reduces the risk of airborne infection for faster relief and treatment.
A Mexican man infected with a highly contagious form of tuberculosis was able to cross into the United States 76 times and fly on multiple domestic flights, reports The Washington Times.
Indeed, if ξt (x) = 1, then inﬁnite infection paths going backwards in time must either stay inside D or cross π , so that, by (p1), ξt (x) = 1 as well.
Scaling of a random walk on a supercritical contact process
For larger N , P (n) crosses over to a pure exponential decay, normalized to 1 − 1/R0 , the probability of the infection surviving to macroscopic size.

Interestingly also B. taylorii infection appears to provide immune cross-protection to B. doshiae infection.
