parts of the country were eradicating nutritional and bacterial diseases. The hookworm, an intestinal parasite, infected and chronically debilitated a great many southerners, perhaps as many as 2 million. In the 1930s, a cooperative study by the
Florida State Board of Health, the Rockefeller Foundation, and Vanderbilt University found the State's adolescents aged 15 to 18 the most affected group (44.7 percent), and the Panhandle the most severely affected area with nearly half of its teenagers (49 .2 percent) infested with hookworm (Eberson, 1980; and Link, 1988). John D. Rockefeller found the situation so appalling in the early twentieth century that he established and funded the Rockefeller Sanitary Commission for the Eradication of Hookworm Disease.

proteolytic cascade. Several of these proteins that are responsible for this proteolytic cascade are also essential for the worm's nutrition and survival. Therefore, a vaccine that could induce antibodies for these antigens could interfere with the hookworm's digestive pathway and impair the worm's survival. Three proteins have been identified: the aspartic protease-hemoglobinase APR-1, the cysteine protease-hemoglobinase CP-2, and a glutathione S-transferase. Vaccination with APR-1 and CP-2 led to reduced host blood loss and fecal egg counts in dogs. With APR-1, vaccination even led to reduced worm burden. Research is currently stymied at the development of at least one of these antigens as a recombinant protein for testing in clinical trials.

interest in the topic of hookworm-related anemia during pregnancy. With the understanding that chronic hookworm infection can often lead to anemia, many people are now questioning if the treatment of hookworm could effect change in severe anemia rates and thus also on maternal and child health as well. Most evidence suggests that the contribution of hookworm to maternal anemia merits that all women of child-bearing age living in endemic areas be subject to periodic anthelmintic treatment. The World Health
Organization even recommends that infected pregnant women be treated after their first trimester. Regardless of these suggestions, only Madagascar, Nepal and Sri Lanka have added deworming to their antenatal care programs.

group, both illustrated rather similar rates in adverse birth outcomes. The treated group demonstrated 5.6% adverse birth outcomes, while the control group had 6.25% adverse birth outcomes. Furthermore, Larocque et al. illustrated that treatment for hookworm infection actually led to positive health results in the infant. This study concluded that treatment with mebendazole plus iron supplements during antenatal care significantly reduced the proportion of very low birth weight infants when compared to a placebo control group. Studies so far have validated recommendations to treat infected pregnant women for hookworm infection during pregnancy.

future economic productivity. In 2001, the 54th World Health
Assembly passed a resolution demanding member states to attain a minimum target of regular deworming of at least 75% of all at-risk school children by the year 2010. A 2008 World Health Organization publication reported on these efforts to treat at-risk school children. Some of the interesting statistics were as follows: 1) only 9 out of 130 endemic countries were able to reach the 75% target goal; and 2) less than 77 million school-aged children (of the total 878 million at risk) were reached, which means that only 8.78% of at-risk children are being treated for hookworm infection.

While reinfection may occur, it is still recommended that regular treatments be conducted as it will minimize the occurrence of chronic outcomes. There are also increasing concerns about the issue of drug resistance. Drug resistance has appeared in front-line anthelmintics used for livestock nematodes. Generally human nematodes are less likely to develop resistance due to longer reproducing times, less frequent treatment, and more targeted treatment. Nonetheless, the global community must be careful to maintain the effectiveness of current anthelmintic as no new anthelmintic drugs are in the late-stage development.

808:, where the heaviest parasitic loads tend to occur in children, hookworm prevalence and intensity can be higher among adult males. The explanation for this is that hookworm infection tends to be occupational, so that coworkers and other close groups maintain a high prevalence of infection among themselves by contaminating their work environment. However, in most endemic areas, adult women are the most severely affected by anemia, mainly because they have much higher physiological needs for iron (menstruation, repeated pregnancy).An interesting consequence of this in the case of

The community-directed treatment model used in this specific study allowed villagers to take control of the child's treatment by having villagers select their own community drug distributors to administer the antihelminthic drugs. Additionally, villagers organized and implemented their own methods for distributing the drugs to all children. The positive results associated with this new model highlight the need for large-scale community involvement in deworming campaigns.

all of these larvae are stimulated to re-enter the circulation (presumably by sudden hormonal changes), then to pass into the mammary glands, so that the newborn baby can receive a large dose of infective larvae through its mother's milk.

Australia. An identical phenomenon is much more commonly seen with

The goal of vaccine development is not necessarily to create a vaccine with sterilizing immunity or complete protection against immunity.
