Schlüsselwörter (Englisch)

Kurzbeschreibung (Englisch)

The highest burden of meningococcal disease in the world is in sub-Saharan Africa, in an area that is referred to as the meningitis belt. In order to contribute to a better understanding of the underlying mechanisms, we perform long-term analyses of the major causative agents of bacterial meningitis and the dynamics of carriage of Neisseria meningitidis in the Kassena-Nankana District of Northern Ghana.

Projektziele (Englisch)

The purpose of the studies is firstly, to determine whether patterns of carriage during inter-epidemic and pre-epidemic periods can help to elucidate the precipitating factors of major epidemics of meningococcal meningitis, and secondly, to provide background information to underpin clinical trials of new meningococcal and pneumococcal vaccine formulations in Africa.
