Public health officials in the United States are addressing infec- tious diseases elsewhere in the world because pathogens can emerge in one region and spread. Information on emerging diseases is widely available—on the Internet, in books and magazines, and through news reports. With health information readily available, individuals can become more proactive and responsible for reducing their risk of communicable diseases, including emerging infections. Applying Health Skills Advocacy. Choose one emerging infection to research. Prepare a script for a public service announcement describing this disease. Be sure to include information on how the disease is transmitted and what the symp- toms are. Urge individuals who suspect they may be infected to seek medical attention immediately. Share your script with the class. Precautions to avoid emerging or reemerging infections: What You Can Do Take all of the antibiotics prescribed by your doctor. Eat only fully cooked eggs. Avoid swallowing water at water parks. Take precautions to prevent bites by vectors such as ticks and mosquitoes. health.glencoe.com HS_HEALTH_U08_C24_L3 12/8/03 5:29 PM Page 641

H E A L T H smallpox for 25 years, thanks in large part to Dr. D. A. Henderson. He ran the World Health Organization’s smallpox-eradication program and has been the chief smallpox adviser to the feder- al government. Henderson believes a smallpox outbreak in the United States would be “very controllable.” The strategy he used in the 1960s and 1970s was to vaccinate only infected patients and people in contact with those patients, mov- ing outward geographically in concentric circles until the virus stopped spreading. For those who don’t get a precautionary vaccination, the small- pox vaccine still protects against the disease if given within two or three days after infection. O utside of military personnel, who should get a shot to protect themselves against small- pox? It’s a tricky question, because this particular vaccine is one of medicine’s most dangerous. Most people just get a blister at the injection site and maybe some swelling of the arm. About a third will feel ill enough to miss work or school. Out of 1 million people, between 15 and 60 will develop serious complications, including encephalitis (swelling of the brain). If the entire population of the United States were to be vacci- nated, 250 to 500 Americans would probably die. Luckily, doctors can often tell in advance who is most at risk. Pregnant women and small chil- dren, for example, are particularly vulnerable. So is anyone whose immune system is compro- mised. All told, 60 million Americans would probably be well advised to take a pass. Is It Worth the Risk? According to a survey, two out of three Americans are willing to risk their health to pro- tect themselves against a disease that doesn’t really exist. There hasn’t been an outbreak of A Smallpox Shot A Smallpox Shot The smallpox vaccine works but carries real risks. Who should take it?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
