LONDON, Aug 17 (Reuters) - The worst outbreaks of measles in years are
infecting thousands and killing hundreds across Africa and offer tragic
evidence of what happens when health authorities drop their guard on
this highly contagious disease.
Health experts say dramatic success in the past decade in boosting
global measles vaccination cover and cutting death rates has led to
dangerous levels of complacency in some countries, and policy focus and
funds have drifted away.
Even mothers -- who until recently in some of the worst hit countries
didn't even name their children until they had survived measles -- have
been lured into a false sense of security, believing the disease has
been beaten and they no longer need to bother to visit clinics for
immunisations.
About 164,000 people died from measles in 2008, down 78 percent from
733,000 in 2000, according to the Measles Initiative, which groups
organisations like the United Nations children's fund (UNICEF) and the
World Health Organisation.
But UNICEF fears the combined effect of decreased political and
financial commitment to measles could reverse the gains, resulting in
an estimated 1.7 million measles-related deaths globally between 2010
and 2013.
"Measles is so infectious, and given a little space it will spread
really fast," Andrea Gay, director of children's health at the United
Nations Foundation, told Reuters.
Africa is already experiencing some of its largest and most deadly
measles outbreaks in years and more than 1,400 people, many of them
young children, have died so far this year.
The African death toll is so far relatively small compared with India,
which accounted for around 75 percent of child deaths from measles in
2008, but the risk is that continued complacency will allow this
preventable virus to spread rapidly.
According to the WHO, more than 28 countries in Africa have suffered
outbreaks of measles this year. Some of the worst hit are Lesotho,
Malawi, Namibia, South Africa, Zambia and Zimbabwe.
Health officials in Malawi say the viral disease has killed 197 people
and infected 77,000 since January -- the highest numbers recorded there
in the past decade.
LAPSES IN VIGILANCE
Edward Hoekstra, a New York-based specialist with UNICEF's Global
Measles Programme said experts' greatest fears -- that the success
against the disease could be reversed when efforts to keep it at bay
lapse -- are already starting to be realised.
"In the past in Africa, every mother knew about measles. They knew it
killed children. Sometimes they wouldn't even name their children until
after they had survived measles," he said in a telephone interview.
"But now they don't see it so much any more and there has been a drop
in demand (for vaccinations)."
Lapses in vigilance about measles are not confined to Africa --
outbreaks of the disease have been recurring in the United States,
Britain and other rich nations where suspicions about possible
side-effects from combination vaccines led to significant drops in
coverage rates in recent years.
In Africa's poorest nations, where victims may be malnourished or have
weakened immune systems, measles can quickly become a killer.
In 2009, more than 2.4 million children in eastern and southern Africa,
about 20 percent of all children under one year, were not being reached
by routine immunisation, according to the United Nations.
With the death toll on the rise, Malawi's health ministry has embarked
on a major vaccination campaign, focusing on rural areas where 80
percent of its 13 million population lives.
It costs less than $1 to vaccinate a child against measles, and two
doses of the jab are required for full protection.
To get coverage rates above the 90 percent rate needed to effectively
conquer the disease, the WHO advises high-risk countries to conduct
national vaccination sweeps every three years to cover those who missed
out on jabs as babies.
Experts say the "out of sight, out of mind" mentality is also affecting
international donors -- particularly when health aid funding is being
squeezed by a global economic downturn. The Measles Initiative is
facing a $59 million shortfall for 2010.
"What's frustrating is that we're only talking about around 50 million
dollars or so -- that's really a small amount on the global health
agenda," said Hoekstra
