In 2004，the World Health Organization，WHO，warned of a possible outbreak of another serious disease which may be even more deadly than SARS．The WHO believes that it is likely that bird flu will spread to human beings in the next few years．If it does，up to seven millions people could die from the disease．

Diseases like bird flu are caused by viruses，that is，tiny things which change and be come more dangerous over time．When a new type of a common virus changes，it may be able to get past the body’S immune system．If that happens，humans are in great danger until a cure or treatment becomes available．

There have always been viruses and people always get sick，of course，but as we saw with SARS，the situation is more difficult today．People travel more than ever before，which means that disease can spread quickly and across large areas――in fact the whole world．

Scientists are already working on drugs that will prevent or limit the effect of a new virus，but the process takes time．It is just as important to make sure that countries，especially poor countries，are prepared to deal with the disease。New disease usually affect poor areas the most，so we must help develop health care in all countries．

Dogs have long been used to find explosives and drugs．Now，a new study shows that man’s best friend can also help to find lung and breast cancer，researchers report in integrative Cancer Therapies．The findings show that trained ordinary household dogs can detect early―stage lung and breast cancers by smelling the breath samples of patients．

Researchers have found that cancer cells send out molecules different from those of healthy ones，and that might be sensed by smell by the highly sensitive dog’s nose．

For the study，five dogs were trained by a professional instructor to respond differently to breath samples of healthy and cancer patients．“The dogs learned to sit or lie down in front of cancer patient samples and to ignore control samples through the method of food reward，” McCulloch explained．

After a period of training，researchers tested the animals’ability to distinguish cancer patients from controls．The animals were given breath samples from 55 patients with lung cancer，3 1 with breast cancer and 83 healthy controls who were not included in the original training period．

McCulloch’s group found that the dogs were able to correctly distinguish the breath samples of cancer patients from those of the control subjects in about 90 percent of the cases．The dogs were also able to detecting early-stage lung and breast cancers．

“These results show that there is hope for early detection，”McCulloch said．The re-searches are planning to conduct further studies on the breath composition of cancer patients to possibly design an electronic device that can do the dogs’job．“A dog’s nose is so powerful it can detect odors（气味）10 000 to 100 000 times better than a human nose can．I hope people will be interested in doing this research，”McCulloch added，“It shows that there is definitely something out there．”
