Economic impact of cystic echinococcosis in Peru
Moro PL , Budke CM , Schantz PM , Vasquez J , Santivanez SJ , Villavicencio J . PLoS Negl Trop Dis 2011 5 (5) e1179 BACKGROUND: Cystic echinococcosis (CE) constitutes an important public health problem in Peru. However, no studies have attempted to estimate the monetary and non-monetary impact of CE in Peruvian society. METHODS: We used official and published sources of epidemiological and economic information to estimate direct and indirect costs associated with livestock production losses and human disease in addition to surgical CE-associated disability adjusted life years (DALYs) lost. FINDINGS: The total estimated cost of human CE in Peru was U.S.$2,420,348 (95% CI:1,118,384-4,812,722) per year. Total estimated livestock-associated costs due to CE ranged from U.S.$196,681 (95% CI:141,641-251,629) if only direct losses (i.e., cattle and sheep liver destruction) were taken into consideration to U.S.$3,846,754 (95% CI:2,676,181-4,911,383) if additional production losses (liver condemnation, decreased carcass weight, wool losses, decreased milk production) were accounted for. An estimated 1,139 (95% CI: 861-1,489) DALYs were also lost due to surgical cases of CE. CONCLUSIONS: This preliminary and conservative assessment of the socio-economic impact of CE on Peru, which is based largely on official sources of information, very likely underestimates the true extent of the problem. Nevertheless, these estimates illustrate the negative economic impact of CE in Peru. |
Epidemiologic and zoonotic aspects of ascarid infections in dogs and cats
Lee AC , Schantz PM , Kazacos KR , Montgomery SP , Bowman DD . Trends Parasitol 2010 26 (4) 155-61 Toxocaracanis and Toxocara cati of dogs and cats, respectively, can cause significant disease in people. Human seroprevalence for Toxocara antibodies varies with factors such as geographic location, socio-economic status, and dietary habits. Risk factors for infection include geophagia and low-level education. Toxocara canis is better recognized as a cause of human toxocariasis, but Toxocara cati should not be overlooked. In addition, patent infections with Baylisascaris procyonis, the raccoon ascarid, have been increasingly recognized in dogs. Pet owners need to be properly educated about zoonotic risks, and veterinarians should institute regular parasite screening and treatment for all pets. Establishment of national surveillance programs to determine the incidence and specific etiological agent in human larva migrans patients would aid in the development of targeted intervention strategies. |
Toxoplasmosis prevention and testing in pregnancy, survey of obstetrician-gynaecologists
Jones JL , Krueger A , Schulkin J , Schantz PM . Zoonoses Public Health 2009 57 (1) 27-33 Summary: Toxoplasmosis in pregnant women can lead to congenital disease with severe neurological and ocular complications in the foetus. In 2006, we surveyed US obstetrician-gynaecologists to determine their knowledge and practices about toxoplasmosis prevention and testing. Questionnaires were mailed (four mailings) to a random sample of 1200 of the 33 354 members of the American College of Obstetricians and Gynecologists (ACOG). Of the 1200 surveyed, 502 (42%) responded. The respondents were similar to all ACOG members by gender, region of the country and practice type (P > 0.5), and age (respondents were slightly younger, mean 46 years versus 47 years). To prevent toxoplasmosis, most respondents indicated that they counsel pregnant women about cat litter (99.6%), but fewer counselled about eating undercooked meat (77.6%), handling raw meat (67.4%), gardening (65.4%) or washing fruits and vegetables (34.2%). Many (73.2%) respondents were not aware that some Toxoplasma IgM tests have had a high false positive rate, and most (91.2%) had not heard of the avidity test, which can help determine the timing of Toxoplasma gondii infection in relation to pregnancy. There is a need for more education about T. gondii serological testing, particularly the Toxoplasma avidity test. US obstetrician-gynaecologists are providing beneficial counselling to their patients, but could provide more information about undercooked meat and soil risks. |
