The patients’ ages ranged from 3 months to 2 years, and thecourses of disease were 3 days to 2 years. For most of cases, we had got a satisfactory effect after 3curative courses.

Poliomyelitis is a very contagious viral infection caused by poliovirus. Children are principally attacked. In this paper, we assess the impact of vaccination in the control of spread of poliomyelitis via a deterministic SVEIR (Susceptible-Vaccinated-Latent-Infectious-Removed) model of infectious disease transmission, where vaccinated individuals are also susceptible, although to a lesser degree. Using Lyapunov-Lasalle methods, we prove the global asymptotic stability of the unique endemic equilibrium whenever ?. Numerical simulations, using poliomyelitis data from Cameroon, are conducted to approve analytic results and to show the importance of vaccinate coverage in the control of disease spread.展开更多

Methods We used cell culture, long‐overlapping RT‐PCR, and spot hybridization assays to verify and accurately locate the sites of action of ozone that cause PV1 inactivation. We also employed recombinant viral genome RNA infection models to confirm our observations. Results Our results indicated that ozone inactivated PV1 primarily by disrupting the 5′-non‐coding region(5′‐NCR) of the PV1 genome. Further study revealed that ozone specifically damaged the 80‐124 nucleotide(nt) region in the 5′-NCR. Recombinant viral genome RNA infection models confirmed that PV1 lacking this region was non‐infectious. Conclusion In this study, we not only elucidated the mechanisms by which ozone induces PV1 inactivation but also determined that the 80‐124 nt region in the 5′‐NCR is targeted by ozone to achieve this inactivation.展开更多
