Bottom Line: The objective of this paper is to explain through the ecological hypothesis superinfection and competitive interaction between two viral populations and niche (host) availability, the alternating patterns of Respiratory Syncytial Virus (RSV) and influenza observed in a regional hospital in San Luis Potosí State, México using a mathematical model as a methodological tool.The data analyzed consists of community-based and hospital-based Acute Respiratory Infections (ARI) consultations provided by health-care institutions reported to the State Health Service Epidemiology Department from 2003 through 2009.

Scalograms (absolute values) for the periods between 8 and 128 weeks (2003–2009).(A) Total influenza cases. (B) Total RSV cases. Horizontal axis, weeks numbered consecutively starting 2003; vertical axis, periods in weeks.

Mentions: Finally we show a very interesting phenomenon. We performed the scalogram analysis looking for periodic cycles of longer scales. Fig. 6 shows the results. One can see that influenza has a cyclic periodic behavior across weeks of about 128 weeks (32 months or roughly 3 years).
