Nairobi - Clinical studies conducted recently across Africa show a
clear association between circumcision and HIV seropevalence. It may
well be the poor genital hygiene among non-circumcised males that
elevates their risk of contracting HIV, reports OSCAR OBONYO
Recent studies comparing HIV/Aids rates among circumcised and
uncircumcised men in Africa now show, on average, three times more HIV
infection among the uncircumcised.
Clinical studies conducted in the continent over the last five years
show evidence of geographical clusters of high seropositivity in certain
countries.
According to Dr Stephen Mosses's lead study, "Geographical Patterns
of Male Circumcision Practice in Africa: Association with HIV
Seroprevalence", ethnic groups where adult HIV levels were below one per
cent in sub-Saharan Africa, 97 per cent of the males are circumcised,
and where the levels were above 10 per cent, only six per cent of males
are circumcised.
Dr Moses, who has reviewed 30 studies, primarily from Africa, reveals
that this association has been observed in studies carried out among
more than 40 circumcising and non-circumcising communities across
Africa.
Lack of male circumcision has been associated with high levels of HIV
in sub-Saharan Africa, which according to the World Health Organisation
(WHO) represents 68 per cent of the global infection.
In Kenya, the data is telling. Some of the communities that
traditionally do not practice circumcision are most ravaged by the
pandemic.
According to statistics of the National Aids and Sexually Transmitted
Infections Control Programme (NASCOP), the largest non-circumcising
community in the country - the Luo, for instance, is worst hit by
HIV/Aids.
Basing their arithmetic on Kenya's big tribes, researchers note that
the Luo who constitute only 12.38 per cent of the country's population
account for 29.2 per cent of the HIV/Aids cases as compared to the
Kikuyu of central Kenya who constitute 20.78 per cent and the Luhyia of
Western Kenya 14.8 per cent (1995) yet they account for only 9.2 per
cent and 9.1 per cent of the cases, respectively.
Biological evidence points to increased susceptibility (among
uncircumcised males) of the flesh under the foreskin to inflammation,
abrasions during intercourse and prolonged viral survival due to warmth
and moistness under the "sheath" of the uncircumcised.
Dr William Cameron, an associate professor at the University of
Ottawa in Canada, who has co-authored several African studies, reveals
that several studies have established that such sexually transmitted
diseases as syphilis and chancroid occur more frequently among the
uncircumcised.
Researchers argue that it may well be the poor genital hygience among
non-circumcised male rather that their non-circumcised status that
elevates their risk of contracting HIV.
A number of reasons have been floated, though, to explain the
apparent ease of HIV transmission among non-circumcising ethnic
communities in Kenya. Social, economic and cultural factors have been
implicated in the elevated risk of transmission, including polygamy,
widow inheritance, population mobility and sexual networking.
NASCOP reports that by 1998, adult HIV prevalence had increased to
about 13.9 per cent. The prevalence in urban and rural areas is
estimated to be 17-18 and 12-13 per cent respectively. Close to 400
people die everyday due to HIV related diseases, says NASCOP in its
latest report, "Aids in Kenya: Background Projections Impact
Interventions Policy".
Despite the devastating impact, the government and medical
authorities have refused to divulge information on the link between
HIV/Aids and circumcision claiming such a disclosure is "tantamount to
licensing circumcised Kenyans to have unprotected sex".
"Though it is increasingly becoming evident that there is a link
between the two, there are fears in some quarters that such information
should not be relayed to the public,' a medical doctor at Kenyatta
National Hospital who sought anonymity says.
Government authorities ought to be embarrassed of advancing such
simplistic arguments, argued Mr. Edmond Kwena. "Most Kenyans are now an
informed and educated lot and the assumption that they need to be
protected from making erroneous decisions is an abuse to this country"
Noting that the crucial challenge lies in how and not whether to
relay the information, Kwena says that it is this very lack of openness
that has made Kenya lag behind in the Aids campaign in the continent.
Most recently, a study in the lake side town of Kisumu by Mark
Tyndall and Allan R. Ronald also found out that more uncircumcised men
than their circumcised colleagues having contact with commercial sex
workers recorded a higher HIV positivity rate.
However, Isabelle de Vencenzi and Thiery Mertins in their study
(1994), "Male Circumcision: A role in HIV Prevention?" argue that the
association between HIV and circumcision is weakened when factors such
as contact with commercial sex workers, ethnic origin and birth place
are adjusted for.
"Such inconsistent findings suggest that researchers cannot, at this
stage, recommend male circumcision as a policy in controlling HIV
infection,' they say.
Evidence from studies validating circumcision as a control measure
is, however, outweighing. In 1986, Dr Thomas Wiswell studied records of
more than 200,000 male infants born in US Army hospitals worldwide. He
found that circumcised boys were ten times more likely to suffer from
urinary-tract infections (UTIs). He discovered, too, that 1.4 percent of
uncircumcised male infants suffered UTIs in the first year of life.
Wiswell's figures translated into 5,000 to 10,000 UTIs a year.
"There is overwhelming proof that circumcision may protect against
foreskin infections and sexually transmitted diseases including
HIV/Aids. One gets multiple benefits from one procedure."
