The changing epidemiology of invasive meningococcal disease in Canada, 1985 through 1992: emergence of a virulent clone of Neisseria meningitidis
Article Abstract:
The incidence of invasive meningococcal disease (IMD) appears to have increased in Canada since 1985. IMD is caused by the organism Neisseria meningitidis. Researchers reviewed national health surveillance information to determine the incidence of IMD and the number of deaths caused by the disease from 1985 to 1992. The incidence of the disease peaked yearly between December and March. There was an increase in group C organisms as the causative agent of IMD from 24% in 1985 to 65% in 1992. Of the 761 of the 1,007 group C isolates submitted for further testing, 69% were identified as strain ET-15. Of those infected with ET-15, 17.8% died compared with 10.9% of those infected with other strains of group C. Six percent of those infected with group B died compared with 14.5% of those infected by group C organisms.

Chlamydia pneumoniae as a new source of infectious outbreaks in nursing homes
Article Abstract:
Chlamydia pneumoniae may be responsible for many cases of respiratory illness in nursing homes. In 1994, three nursing homes in Ontario reported outbreaks of respiratory illness of unknown cause. An investigation of some cases by the Ottawa health department revealed the presence of Chlamydia pneumoniae in some blood samples. A retrospective study of the three nursing homes showed that almost half of the residents had confirmed or suspected Chlamydia pneumoniae respiratory illness. Sixteen developed pneumonia and six died.

Toward Control of Meningococcal Disease: Reducing Risk in College Students
Article Abstract:
It may be cost-effective to vaccinate all college freshmen against meningococcal infections. These infections normally affect children but can also affect young adults, who have a higher mortality rate from the infection. A study published in 2001 showed that college freshmen who live in dorms have an especially high risk of meningococcal infection.
