| bacterial meningitis--a five year review 1975--1979. | in a five year period 142 cases of bacterial meningitis were reported, of which 50 per cent were children under the age of four years and a third of the children were neonates. the commonest organism isolated was streptococcus pneumoniae, there being 28 cases. the incidence of klebsiella organism causing meningitis has been on the increase, and 20 cases were reported within this period. there has been a change in pattern of neonatal meningitis, with group b streptococcal infection predominating ... | 1981 | 6792976 |
| meningococcal carriage in umra pilgrims returning from saudi arabia. | moslems from all over the world go to mecca and medina in saudi arabia for two types of pilgrimage: the major pilgrimage (hajj) and the minor (umra). an international outbreak of meningococcal disease with serogroup w-135 occurred in association with hajj pilgrimage in the years 2000 and 2001, and it has been shown that pharyngeal carriage of a single w-135 strain was high in returning hajj pilgrims. we investigated the meningococcal carriage in umra pilgrims to determine the extent of circulati ... | 2003 | 12757687 |

| emergence and disappearance of w135 meningococcal disease. | w135 meningococcal disease was imported into singapore in 2000 via hajj pilgrims. previous studies have showed sustained carriage of w135 with the potential for further transmission within communities. we therefore set out to determine whether w135 meningococcal disease would become endemic in singapore after its introduction in 2000. cases occurred until 2003, but no further cases have been reported since 2004. | 2010 | 19845997 |
| hajj-associated outbreak strain of neisseria meningitidis serogroup w135: estimates of the attack rate in a defined population and the risk of invasive disease developing in carriers. | an outbreak of disease due to neisseria meningitidis serogroup w135 (w135) occurred in 2000 and 2001 among pilgrims returning from the annual islamic pilgrimage to saudi arabia (the hajj) and in their contacts. for the hajj in 2000, the attack rate of w135 disease was 25 cases per 100,000 pilgrims. after the introduction of quadrivalent meningococcal vaccine for the hajj in 2001, no pilgrim developed w135 disease. the estimated attack rates for household contacts of returning pilgrims were 18 ca ... | 2003 | 12627350 |
| w135 meningococcal carriage in association with the hajj pilgrimage 2001: the singapore experience. | an international outbreak among pilgrims returning from the hajj (pilgrimage to mecca) and their close contacts was caused by w135 neisseria meningitidis. in singapore, this strain is a new emerging problem, clearly associated with this outbreak. we investigated the extent of transmission of n. meningitidis in hajj pilgrims and their contacts, in order to provide evidence for developing a rational public health policy. we found a high acquisition rate of w135 n. meningitidis in singaporean pilgr ... | 2003 | 12615373 |
