1 a large plastic or paper bag with handles, used to carry things that you have bought, especially one given to you in a shop -- 购物袋
2 someone who does not suffer from a disease but has the infection or genetic fault that causes it and can give the disease to someone else -- 带菌者；病毒携带者
Lastly, evidence suggests that apparently resistant host genotypes may sometimes be able to act as subclinical carriers of infection.
In the two implicated restaurants, the most likely mechanism of contamination was through faecal contamination of food handled by the two employees identified as carriers.
No information on incubation period was available and no carriers were identified.
Female carriers have a life expectancy of 81 years and non-carriers 83 years.
Any effect would reduce the differences between carriers and non-carriers.
Invasive disease is a rare outcome of infection and asymptomatic carriers are responsible for most transmission of these organisms.
In dynamic models of the evolution of a disease in a population it is often important to distinguish between carriers and non carriers [4].
With regard to the impact of vaccination, the model implicitly yet heuristically takes account of the distinction between carriers and noncarriers.
