Progress Toward Poliomyelitis Eradication--West Africa, 1997-September 1998
Much progress has been made in western Africa to eradicate polio but more effort is needed. Polio cases continue to occur because vaccination rates are low. In 1997, only three of 15 west African countries reported vaccination rates greater than 70%. During January 1997-June 1998, all but two countries administered supplementary vaccine during National Immunization Days (NIDs). During January-September 1998, 189 cases of paralysis were reported in West Africa. During the same period, wild poliovirus type 1 was isolated from 15 people with paralysis in Benin, Burkina Faso, Ghana, Cote d'Ivoire, Niger, and Senegal.

An outbreak of multidrug-resistant, quinolone-resistant Salmonella enterica serotype typhimurium DT104
An outbreak of Salmonella food poisoning in Denmark was traced to a herd of pigs. It affected 25 people, 11 of whom were hospitalized and two died. Doctors who treated the patients discovered that the bacterium was a strain of Salmonella enterica serotype typhimurium DT104. This strain is already known to be resistant to several antibiotics and in these cases, it was also resistant to fluoroquinolone antibiotics. This is probably due to the fact that these antibiotics are used in food animals.
