In this paper, we examine the attitudes of 16- to 19-year olds towards stealth viral marketing in the form of videos posted on websites such as Youtube. Apart from their general attitudes towards the phenomenon, we were also concerned with their views on the ethics involved in this marketing method and how this affects their view on the companies behind the advertising. To accomplish this, we administered a survey to a sample chosen by convenience. Using the Persuasion Knowledge Model and prior research on the subject, we then analyzed the gathered data and reached the conclusion that the respondents in our sample were mainly positive towards stealth viral marketing in this particular form, that they generally did not consider it unethical and that even though most considered the companies to be responsible for such videos, teenagers were not likely to take negative actions against them if they found out that a video that they had seen was in fact a stealth viral video.

El presente estudio tuvo como objetivo determinar la seroprevalencia de los agentes neumotrópicos como los virus de la Diarrea Viral Bovina (VDVB), Respiratorio Sincitial (VRS) y Parainfluenza 3 (VPI3) en rumiantes de la comunidad de Chahuaytiri, provincia de Calca, Cusco, a través de la detección de anticuerpos en el suero sanguíneo de alpacas (n igual 21), bovinos (n igual 66) y ovinos (n igual 152) mediante la prueba de neutralización viral (NV). El 15.8±16.4% (3/21), 4.8 ± 9.1% (1/21) y el 23.8±18.2% (5/21) de las alpacas presentaron anticuerpos neutralizantes contra los virus: DVB, RS y PI3. El 90.9±6.9% (60/66), 87.88±7.9% (58/66) y el 81.8 ± 9.3% (54/66) de los bovinos y el 28.29±7.1% (43/152), 49.34 ±7.9% (75/152) y 50.0 ±7.9% (76/152) de los ovinos presentaron anticuerpos contra la DVB, RS y PI3, respectivamente. Estos resultados confirman la presencia de infecciones virales en rumiantes bajo sistema de crianza mixto de la comunidad campesina del Cusco. / The seroprevalence of Bovine Viral Diarrhoea Virus (BVDV), Parainfluenza Virus Type 3 (PI3V) and Respiratory Syncytial Virus (RSV) in serum samples of alpacas (n igual 21), bovine (n igual 66) and sheep (n igual 152) of a rural community of Cusco, Peru. It was carried out by virus-neutralization test. The 15.8±16.4% (3/21), 4.8 ±9.1% (1/21) and 23.8±18.2% (5/21) of alpacas had neutralizing antibodies against BVD, RS and PI3 virus. The 90.9±6.9% (60/66), 87.88±7.9% (58/66) and 81.8 ±9.3% (54/66) of bovine and the 28.29±7.1% (43/152), 49.34 ±7.9% (75/152) and 50.0 ±7.9% (76/152) of sheep had antibodies to BVDV, RSV and PI3V respectively. These results confirm the presence of viral infections in ruminants of mixed breeding system of a rural community.
