African children die of malaria each day.

Plasmodium falciparum is responsible for most human
malaria.

Some 3,000 African children die of malaria each day, which is
equivalent to one death every 30 seconds. Malaria, which dates
back from 450 A.D., may have killed half of all the people who
ever lived.
There are more people infected with malaria now than at any
point in history, and about 2 million people die from the
disease each year. Close to half of those deaths are children
in sub-Saharan Africa.
In response to the growing problem, the World Health Organization
(WHO) and Unicef have published a report to mark Africa Malaria
Day and support a global effort to treat and prevent malaria.
In the last 20 years, the number of malaria cases has quadrupled
and warnings of drug-resistant malaria have been confirmed.
According to the report, chloroquine, which is the least expensive,
most widely available of the malaria drugs, is used so often
that is now close to useless against the disease.
The report is part of a campaign called Roll Back Malaria
(RBM). One of the campaign’s goals is to cut malaria
deaths in Africa in half by 2010.
The report mentions four key strategies to reaching this
goal:
-
Insecticide-treated bed nets should be made widely available.
These bed nets have been found to reduce malaria transmission
by 17 percent, yet fewer than three percent of African
children sleep under such nets.
-
Pregnant women, who along with babies are particularly
at risk, should receive bed nets and anti-malarial medicines
as a priority.
-
Next-generation drugs, which are hundreds of times more
expensive than chloroquine, must be made available to
treat chloroquine-resistant malaria.
-
Malaria Early Warning Systems, which use weather forecasting
and data to help alleviate outbreaks, must be created.
The systems have already proven effective in trials.
Malaria costs Africa about $12 billion a year, and in 2002
African countries contributed $256 million to the new Global
Fund to fight AIDS, Tuberculosis And Malaria.
Female mosquitoes spread malaria (males don’t bite).
There are 170 malaria parasites in total, which mosquitoes
spread between reptiles, birds and mammals. About two-dozen
species of Anopheles mosquito carry human malaria, which results
in symptoms such as fever, chills and cramps. The disease
causes severe anaemia and can result in a blockage of the
blood supply to the brain, which can be fatal.
According to WHO and Unicef, proper treatment and prevention
efforts could reduce malaria transmission by up to 60 percent
and lower death rates in young children by around one-fifth.
