From 2001 to 2004, Switzerland switched from routine vaccination with oral polio vaccine (OPV) to inactivated polio vaccine (IPV), using both vaccines in the intervening period. Since IPV is less effective at inducing mucosal immunity than OPV, this change might allow imported poliovirus to circulate undetected more easily in an increasingly IPV-immunized population. Environmental monitoring is...

Abstract Introduction Polio, which is caused by poliovirus, a contagious, potentially crippling, and deadly disease. Pakistan one of the countries in polio still endemic 21st century. In 2019, 146 cases were reported across country with some resulting deaths.

conclusions health managers in iran should continuously monitor the coverage of vaccination with at least three doses of opv in the level of over 95%, monitor the health of the helmand river water which comes from afghanistan to iran, vaccinate the immigrants and replace bivalent vaccine (bopv) with trivalent (topv) vaccine. context the wild polio virus is disrupted in all countries in the worl...

background and objectives : each year, enteroviruses infect millions of people and cause different diseases. the agents are usually detected using cell culture. rd (rhabdomyosarcoma) and l20b (l cells) are among the recommended cells by the world health organisation (who) for this purpose. even though cell culture is the most common method used in diagnosing enteroviruses in stool specimens, th...

Enteroviruses survived for up to 38 days without diminishing in numbers in extended-aeration sludges maintained at 5 degrees C. In oxidation ditch sludges similarly maintained, enteroviruses survived for up to 17 days without diminishing in numbers. The pHs of the sludges in this study were well inside the pH 6 to 8 corridor in which destruction of enteroviruses by the detergents and ammonia pr...

BACKGROUND The endgame of polio eradication is hampered by the international spread of poliovirus via travelers. In response to ongoing importations of poliovirus into polio-free countries, on 5 May 2014, WHO's Director-General declared the international spread of wild poliovirus a public health emergency of international concern. Our objective was to develop a mathematical model to estimate th...

Excitement mounts as the global health and international development communities anticipate a polio-free world. Despite substantial political and logistical hurdles, only 223 cases of wild poliovirus in three countries were reported in 2012. Down 99% from the estimated 350,000 annual cases in 125 countries in 1988-this decline signals the imminent global eradication of polio. However, eliminati...
