# “Kissing contacts” need to be defined {#article-title-2} EDITOR—In their study Kristiansen et al show high carriage rates of pathogenic strains of Neisseria menigitidis in household and kissing contacts of patients with invasive meningococcal disease.1 While it is easy to define a household contact it may be more difficult to define a kissing contact. There are many types of kiss, ranging from a “peck on the cheek” to much more! In some cultures kissing is as common as shaking hands. In such situations widespread chemoprophylaxis to “kissing contacts” may not be appropriate. It would be valuable to know whether Kristiansen et al placed any restrictions on who was defined as a kissing contact. 1. ↵1. Kristiansen BE, 2. Tveten Y, 3. Jenkins A .

[OpenUrl][1][Abstract/FREE Full Text][2] # Chemoprophylaxic strategy needs to be determined {#article-title-4} EDITOR—The study by Kristiansen et al addresses important questions about the use of chemoprophylaxis in contacts of patients with meningococcal disease.1 We believe, however, that the data presented do not fully support the conclusions. Kristiansen et al found high rates of meningococcal carriers among class 1contacts (12.4%) and advocated the use of chemoprophylaxis in this group, on the basis of their assumption that carrying the pathogenic strain increases the likelihood of contracting the disease. One concern is that this group accounts for only 18 of 42 contacts who … [1]: {openurl}?query=rft.jtitle%253DBMJ%26rft.stitle%253DBMJ%26rft.issn%253D0007-1447%26rft.aulast%253DKristiansen%26rft.auinit1%253DB.-E.%26rft.volume%253D317%26rft.issue%253D7159%26rft.spage%253D621%26rft.epage%253D625%26rft.atitle%253DWhich%2Bcontacts%2Bof%2Bpatients%2Bwith%2Bmeningococcal%2Bdisease%2Bcarry%2Bthe%2Bpathogenic%2Bstrain%2Bof%2BNeisseria%2Bmeningitidis%253F%2BA%2Bpopulation%2Bbased%2Bstudy%26rft_id%253Dinfo%253Apmid%252F9727987%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/ijlink?linkType=ABST&journalCode=bmj&resid=317/7159/621&atom=%2Fbmj%2F318%2F7184%2F665.atom
