Neisseria meningitidis is the major worldwide cause of meningitis and rapidly fatal sepsis in healthy individuals. The risk of meningococcal disease is higher among those with complement deficiencies, asplenia and other underlying conditions. N. meningitidis is the only agent among the major...

External quality assessment (EQA) is part of quality management systems (QMS) and evaluates performance of laboratories, by an outside agency, on material that is supplied specifically for the purpose. ECDC's disease-specific networks organise a series of EQAs for EU/EEA countries. In some...

Effective control of an uncommon vaccine-preventable disease is dependent upon prompt and early recognition and diagnosis. It is often difficult to diagnose diphtheria clinically, particularly in those countries where the disease is rarely seen. Diphtheria is often confused with other...

Haemophilus influenzae is a common cause of respiratory tract infections. Most strains of H. influenzae are opportunistic pathogens and rarely cause invasive disease unless other factors concur (i.e. viral infections, immunological deficits). Nevertheless, invasive bacterial diseases account for...
