Diagnosis: Human larval toxocariasis is suspected mainly when there is leukocytosis, persistent eosinophilia, hypergammaglobulinemia, and hepatomegaly. Other factors to be considered in the diagnosis are age under 4 years and a history of geophagy or exposure to soil contaminated with canine feces. In the case of ocular toxocariasis, the diagnosis is confirmed by ophthalmoscopic examination, and by histopathologic examination of the eyeball if it has been enucleated. Identification of the larvae in tissue is a painstaking procedure that requires serial sections from the pathologic specimen. Even with an organ as small as the eyeball, it is sometimes necessary to study more than 100 sections before finding any larvae. In several extraocular cases, definitive diagnosis was obtained by laparotomy and resection of a visible granuloma on the surface of the liver. Differential diagnosis between ocular larva migrans and retinoblastoma is especially important. In the case of ocular larva migrans, examination of the aqueous humor usually reveals numerous eosinophils. The difficulty of basing the diagnosis on clinical signs and the uncertainty of the diagnosis has stimulated the development of immunobiologic tests. It is estimated that this test is 78% sensitive and 92% specific in the visceral form and 73% sensitive and 95% specific in the ocular form (Schantz and Glickman, 1983). Since larva migrans does not cause pathology in animals, no immunologic tests have been developed for diagnosis, although the tests used for human infection should serve the purpose. Since a high proportion of dogs are born infected, newborn pups are especially important in prophylaxis (Barriga, 1991). It is recommended to treat 2-week-old puppies with any anthelmintic that is effective against ascarids and repeat the medication at 4, 6, and 8 weeks of age (Barriga, 1991). This measure eliminates the parasites before they have time to pass on eggs and contaminate the environment. Therefore, adult dogs should be treated twice a year, or else examined regularly for eggs in feces and treated if they are infected. Although hypobiotic larvae in the bitch are resistant to anthelmintics, treatment can kill the parasites when they renew their migration before they are passed on to the fetuses. Since even the best treatment has not been shown to be more than 50% effective (Barriga, 1991), other complementary measures should be used at the same time. One of these is to reduce the population of stray dogs and require all other dogs to have a socially responsible owner. Dogs should not be allowed to run free in public parks, especially where there are sandboxes for children. Owners can walk their dogs on a leash and pick up their feces in a plastic bag; the feces should then be burned or disposed of in the trash at home. Finally, the most important measure is to educate the public about the transmission of toxocariasis and the importance of washing hands and raw food before eating.

Nevertheless, containment and reduction, if not elimination, of infections through continuous vaccination of the emerging population are likely to succeed. Of the innovators who virtually defeated poliomyelitis viruses, Albert Sabin made many other significant contributions to virology. His work on sandfiy fever, dengue fever, and herpes B virus, all preceding his study of poliomyelitis virus, produced significant discoveries. After the Sabin vaccine was licensed, he played a prominent role in its usage in many countries and devoted his energies in the Pan-American Union and the World Health Organization toward the control and eventual eradication of many childhood illnesses in addition to poliomyelitis. Jonas Salk, throughout his life, continued to lobby for inclusion of his Poliomyelitis 191 killed virus vaccine for usage in the United States. An interesting addendum is that, after the deaths of Sabin and Salk, a program that gave both vaccines to an individual as a preferred course was proposed and recommended by the U. Commission in 1995, approved in 1996 by the American Academy of Pediatrics, and recommended in January 1997 by the Advisory Committee on Immunization Practices of the U. Incidence of indigenous poliomyelitis in 1961, 1988, and 1993 (dotted areas = more than ten cases; hatched areas = one to ten cases; solid areas = zero cases; open areas = no report). The goal of the World Health Organization was the total elimination of poliomyelitis by the year 2000. However, by 2000 the Salk vaccine, after recommendations from the same committees, replaced the Sabin vaccine and is now exclusively used in the United States and most Western countries. Hilary Koprowski went on to make major medical contributions to the development of the rabies vaccine, which is currently in use throughout the world. He additionally developed monoclonal antibodies to type and segregate individual strains of rabies arising in different geographic areas, and with his colleagues developed the first human monoclonal antibody for therapy of nonvaccinated individuals exposed to rabies. He has also been a major contributor to cancer research and the development of human vaccines made from plants. Finally, the ascendance and contributions of Salk, Sabin, and Koprowski refiect a telling change in biomedical research in the United States. Sabin and Koprowski came to the United States as immigrants, and Salk was the son of immigrants. All came from the minority Jewish religious faith that, prior to the 1940s and in some instances until the 1960s, were a group whose members were largely excluded or under Poliomyelitis 195 quota restriction from medical schools, residency programs, or work in premiere research institutes. Instead, admission to join the great adventure of medical research was becoming available to those of talent, regardless of race, religion, gender, or national origin. Thus, the story of the conquest of poliomyelitis and the participation of Salk, Sabin, and Koprowski, in addition to recounting scientific accomplishment, also refiects a changing American culture and a continuing evolution toward a more just and democratic society.

Of the first three, Lassa fever, Ebola, and Hantaviruses, little is known except that they exist and cause frightful diseases. Once infected with any of these viruses, the victim soon suffers profuse breaks in small blood vessels, causing blood to ooze from the skin, mouth, and rectum. Internally, blood fiows into the pleural cavity where the lungs are located, into the pericardial cavity surrounding the heart, into the abdomen, and into organs like the liver, kidney, heart, spleen, and lungs. We currently have no effective vaccines to prevent these potential plagues, although several are undergoing various stages of development. These viruses lie unendingly in wait of transport to introduce them into highly susceptible and distant urban populations. Representatives of this group are Lassa fever virus and Ebola virus, both of which are endemic in Africa.

Twenty years after the death of John Erskine, during the last years of the nineteenth century, Reed, Lazear, Carroll, and Agramonte, under the auspices of the U. These experiments also proved that yellow fever was not transmitted by fomites (inanimate objects or materials capable of conveying disease-producing agents) and that disinfection of clothes and bedding was unnecessary because this disease was not passed by patient-to-patient contact. From this work, Walter Reed and his coworkers are credited with establishing that the agent of yellow fever is a virus. Mosquitoes ingest the viruses when they bite and draw blood from an infected human and then, after a lag period, expel these viruses into the blood of new victims while biting them. Walter Reed was born in 1851 in rural Belroi, Virginia, where his father was a Methodist minister. At the age of seventeen, he became the youngest graduate of the University of Virginia Medical School. He continued his medical education at the Bellevue Medical School (now New York University Medical School) from which he received his medical degree. After the next fifteen years spent at various Army posts, he took a sabbatical leave and went to the newly established Johns Hopkins Medical School in Baltimore. During that time, Reed became acquainted with William Osler, considered the most illustrious physician in North America, and trained in pathology and bacteriology Yellow Fever 119 with William Welsh. Welsh had earlier studied in the newly emerging bacteriology laboratories in Europe established in response to the observations of Koch and Pasteur. In 1893, Reed was appointed curator of the Army Medical Museum and also Professor of Bacteriology at the recently established Army Medical School. He decided to become a physician while serving as a hospital orderly at Fort Custer, Montana. With encouragement from Reed, he studied initially at Bellevue Medical College in New York and received his medical degree from the University of Maryland School of Medicine in Baltimore. He then also trained in bacteriology and pathology at the Johns Hopkins Hospital with William Welsh. In this same year, at the urging of George Sternberg, then Surgeon General of the Army Medical Corps, Reed formed and headed a Commission to do research on yellow fever, and Carroll became second in command. The two civilian physicians, Jesse Lazear and Aristides Agramonte, attended Columbia University Medical School in New York but came from very different backgrounds. Trained in art as well as medicine, he also traveled to Europe where he studied modern bacteriologic techniques. After receiving his medical degree in 1892, he became the first Chief of Clinical Laboratories at the Johns Hopkins Medical School and joined the Yellow Fever Commission in that position. He was born in Cuba and brought to New York City as an infant after his father was killed in an abortive revolt to free Cuba from Spain. He joined the Yellow Fever Commission as a civilian pathologist in charge of laboratories at Military Hospital #1 in Havana and was Chief Physician on the yellow fever ward. Yellow fever was endemic in Cuba and thus endangered all countries with which Cuba traded. In 1898, with the outbreak of the SpanishAmerican War, yellow fever became a primary concern of the U. Therefore, the Yellow Fever Commission was sent to Cuba 120 Viruses, Plagues, and History in 1900. Interestingly, at that time, none of the four members had actually observed a case of yellow fever. Their first aim was to confirm or refute the claim that yellow fever was caused by a bacterium, namely Bacillus icteroides, as first proposed by Guiseppe Sanarelli, an Italian pathologist who injected the bacteria into five South American subjects of whom three died from jaundice. Although the conclusion that bacteria caused yellow fever brought Sanarelli notoriety and awards, the Yellow Fever Commission proved the idea untrue. The bacillus had simply been a contaminant, a passenger in patients with yellow fever; it was not the cause.
