From 1992 to 1996, 95 patients with tetanus were treated in the Chair and Department of Infectious Diseases in Cracow. Most of them came from rural area, and at old age (median 68 years). Small, trivial skin injuries were the most often identified portal of entry. Only few patients applied to doctor after injury for prophylaxis against tetanus. The authors emphasise that small skin injuries, which may be portal of entry for tetanus, should not be left abandoned.
