Mass psychogenic illness attributed to toxic exposure at a high school

Article Abstract:

Doctors and nurses who investigated a case of possible mass psychogenic illness report the experience. Mass psychogenic illness occurs when many people experience symptoms but no environmental cause is found. It can be difficult to distinguish from a bioterrorist attack or an outbreak of infectious disease. In November, 1998, a school teacher in Tennessee became sick shortly after arriving. Several of her students began experiencing symptoms and more and more children became ill as the school was evacuated. One hundred people were affected and 38 were hospitalized. No environmental cause was found for the outbreak.

Effect of introduction of the pneumococcal conjugate vaccine on drug-resistant Streptococcus pneumoniae

Article Abstract:

Five of seven serotypes in the pneumococcal conjugate vaccine, introduced for infants in the US in 2000, are responsible for most penicillin-resistant infection thus a study is conducted to examine the effect of this vaccine on invasive disease caused by resistant strains. The examination revealed that rate of antibiotic-resistant invasive pneumococcal infections decreased in young children and older persons after the introduction of the conjugate vaccine, while there is an increase in infections caused by serotypes not included in the vaccine.
