In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenza-like cases. Influenza is sometimes called “flu” or a “bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus of this influenza.
There are three main types of the influenza virus. The most important of these are types A and B, each of them having several sub-groups. With the instruments at the hospital the doctor recognized that the outbreak was due to a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H.O. published the important news alongside reports of a similar outbreak in Hong Kong, where about 15%—20% of the population had become ill.
As soon as the London doctors received the package of throat samples, they began the standard tests. They found that by reproducing itself at very high speed, the virus had multiplied more than a million times within two days. Continuing their careful tests, the doctors checked the effect of drugs used against all the known sub-groups of virus type A. None of them gave any protection. This then, was something new: a new influenza virus against which the people of the world had no ready help whatsoever. Having isolated the virus they were working with, the two doctors now dropped it into the noses of some specially selected animals, which contact influenza in the same way as human beings do. In a short time the usual signs of the disease appeared. These experiments revealed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply “Asian” flu.
The first discovery of the virus, however, was made in China before the disease had appeared in other countries. Various reports showed that the influenza outbreak started in China, probably in February of 1957. By the middle of March it had spread all over China. The virus was found by Chinese doctors early in March. But China was not a member of the World Health Organization and therefore did not report outbreaks of disease to it. Not until two months later, when travelers carried the virus into Hong Kong, from where it spread to Singapore, did the news of the outbreak reach the rest of the world. By this time it was started on its way around the world.
Thereafter, WHO’s Weekly Reports described the steady spread of this virus outbreak, which within four months swept through every continent.
The “Asian” flu virus

A:was very weak. B:was a killer. C:reproduced very quickly. D:spread very slowly.

Although it is the elderly and the young infants who get the siekest from the flu, it is young children who are most susceptible. In community flu outbreaks, it is not unusual for 30 to 40 percent of children to get the infection, perhaps twice the rate of adult infection.
Flu spreads rapidly from child to child for a number of reasons. First, flu is spread by small respiratory droplets that are coughed or sneezed and float in the air. A well child can catch the flu from being in the same classroom or child care center with an ill child without them ever touching each other. (Contrast this with the way colds are usually spread, by large droplets on people’s hands, making good hand washing an effective preventive strategy. )Also, flu appears to be contagious even the clay before symptoms begin, and because children don’t get as sick as adults with the flu, they other stay in school or clay-care long enough to spread the disease to their classmates.
While few otherwise healthy children have any serious consequences from the flu, it is these children that are the major conduit by which flu spreads through the community and into households. In ordinary households, adults are more frequently infected by children than by other adults. And it is adults with chronic diseases, and the elderly—particularly grandparents—that suffer the major consequences of this virus. One author has aptly referred to children as the "Typhoid Mary’s" of the flu.
Flu Vaccine is the best defense against the flu. It is recommended for all adults over the age of 65, or over the age of 50 if there are sufficient supplies, and for individuals of any age if they are at high risk. Those high risk individuals would include anyone with heart or lung disease, including asthma, and people with diabetes, chronic kidney disease or other chronic conditions.
But recognizing that it is children who spread flu to households, it can be strongly argued to offer flu vaccine to healthy children who are in regular contact with other fanfily members who are at high risk by virtue of their age or underlying illnesses. This will help keep flu out of these households. Even if the grandparent has had flu vaccine, immunizing the grandchildren makes sense because flu vaccine is more reliably protective in younger healthier individuals. In addition, there are about 8 million children in the U. S. who have underlying conditions—most notably asthma—that make them eligible for flu vaccine. Regrettably, three out of four of these children end up ever getting the flu vaccine.
Why does the author compare children to "Typhoid Mary’s" of the flu

A:Children can spread typhoid as Typhoid Mary does. B:They are similar in that both have a very strong spreading force of some epidemic diseases such as the flu or typhoid. C:Children are victims of Typhoid Mary. D:Typhoid Mary’s once spread the flu on a large scale.
