Women may be infected by the HIV virus in a different way than men, according to a recent study release, suggesting it could be even harder to develop a vaccine that would work well on women.
The findings, published in the journal nature, showed most women in the study initially were infected by multiple variants of the HIV virus while all of men initially wee infected by a single variant of the HIV virus.
Previous studies in the United States and Europe on how the HIV virus was transmitted focused mainly on men and led many to believe that only one variant of the virus was transmitted at the time of infection. The new study appeared to confirm that to be the case in men, but not in women.
Once infected by single or multiple variants of HIV, the virus replicates itself into even more genetic variants, making it difficult to develop a vaccine.
The ongoing study, led by the Fred Hutchinson Cancer Research Center of Seattle, is one of many aimed at better understanding the HIV virus in the belief that the best way to find a vaccine is to understand how the virus works.
The study tracked the sexual activity of hetero-sexual men and women in Kenya over more than four years, monitoring them for the presence of the HIV virus at intervals of about three months.
Of the 32 women infected, 20 were found to have been infected with multiple variants of the HIV virus. Further tests revealed each of the women was infected by a single partner, indicating they had contracted a variety of strains of HIV from one man, not several. Of the 10 men in the study who were infected, all were infected with a single variant of the HIV virus.
Like many medical studies, this one raises more questions than it answers. One question must be addressed is whether HIV infects women in a different way than men.
Students comparing how the virus behaves in men and women are becoming increasingly important as the number of women infected has risen. [br] According to the passage, most women ______.
选项
A、were infected by a single variant of the HIV virus
B、were infected by multiple variants of the HIV virus
C、were stronger than men
D、had anti-body in their body
答案
B
解析
事实细节题。文章第二段showed most women in the study initially were infected by multiple variants of the HIV virus while all of men initially were infected by a single variant of the HW virus.该句表明大部分女性最初都是被病毒的多样变体感染的。所以B是正确答案。A“被艾滋病毒单一变体感染”因此是不正确的:C“比男人强壮”不仅和文章的内容毫无
