11. - Radioactive atoms are unstable because they have too much energy. When they release energy, they are said to decay.

1.What are the challenges in combating emerging and reemerging diseases? 2.Discuss some of the examples given your book. 3.Some steps we can take to prevent an outbreak of the diseases. Emerging Infectious Diseases LEARNING OBJECTIVE 14-19 List several probable reasons for emerging infectious diseases, and name one example for each reason. Emerging infectious diseases (EIDs) are diseases that are new or changing, are showing an increase in incidence in the CHAPER 14 . Princlples of Disease and Epidemiologg 411. recem past, or show a potential to increase in the near future (see Chapter 1). An emerging disease can be caused by a virus. a bacterium, a fungus, a protonoan, or a helminth. About 75% of emerging infectious diseases are zoonotic, mainly of viral origin, and are likely to be vecton borne. Several criteria are used for identifyiog an HiD, For exam. ple, some diseases present symptoms that are cleady disinctive from all other diseases. Some are recogrized because improved diagnostic techniques allow the identification of a new parbogen. Others are identified when a local disease becoines widespread, a rare diskase becomes common, a mild diseas becomes more severe, or an increase in life span permits a alow. disease to develop. Examples of emerging infectious diseases are listed in Table 14.5 and described in the boses in Chapters 8 and 13 (pages 218 . and 367 ) . A variety of factoss contribute to the emerpence of nicw infectious diseases: - New srains, such as E. coli 0157417 and avian influcaza (H5N1). may result from genetic recoenbination between organisms. - A new serovar, sich as Videio dolerae O139, may resulh from changes in or the evolution of existing microorga niams. - The widespread, and sometimes unwarranted, use of antiblotics and pesticides encourages the growth of mote resistant populations of microbes and the vectors (mosquitoes, lice, and eicks) that carry then. - Clobal warming and changes in weather patterns mayy increase the distribution and survival of reervairs and vectors. resulting in the insrodaction and dissemination of diseases. such as malaria and Handavines palmonary syndrome. - Known diseases, such as Zika virus discase, chikungganya. dengue, and West Nile encephalitis, may spread to new geographic areas by modern transportation. This was less likely 100 years ago, when tavel took vo long that infected traveless either died or recovered during passage - Insect vectors transported to new areas can transmit infections brought by human traveles. The African yellow fever mosquito. Aedes aedppli came to the Anecicas with the first European explorers. Yellow ficver yinus was also. brought to the Americas with those first exploren, and A aegypti transmitted the disease to native populations and immigrants alike. The A sian eiger mosquito, A . allopitrie, was. inadvertently brought to Texas on a cargo ship from lapan in 1985. Both Ades ypecies are now estaklished throughout the southem and southwestern stares..
