Malaria deaths higher than expected, study finds

Recent findings show the number of malaria-related deaths is nearly twice as high as previously thought. But other experts have doubts about the methods used to produce these estimates.

  • A mosquito strikes

    Malaria - a single bite can kill

    A mosquito strikes

    Africa's most dangerous animal is about six millimeters long and known as the Anopheles mosquito. It can spread malaria, an infectious disease that kills approximately one million people worldwide each year according to some estimates. Cramps and high fevers that alternate with chills are symptoms of malaria. And the disease can lead to a particularly swift death for young children.

  • Where it all begins

    Malaria - a single bite can kill

    Where it all begins

    If a mosquito bites an infected individual, it can pick up the malaria parasites and spread them to other victims. In this mosquito, researchers marked the malaria parasites with proteins that light up in green. As the light shows, the parasites reproduce in the mosquito's intestines before gathering in its salivary glands.

  • Harvesting the infection

    Malaria - a single bite can kill

    Harvesting the infection

    The biological name for malaria parasites is Plasmodium. In order to investigate the disease, researchers infected Anopheles mosquitoes and then isolated the parasites from their salivary glands. It is there that the infectious form of the parasites accumulates. This image shows a mosquito to the right and its removed salivary glands in the middle.

  • Going in circles

    Malaria - a single bite can kill

    Going in circles

    Since malaria parasites are curved, they move in a circle when researchers place them on a piece of glass with some fluid. The parasites are marked in yellow, and the paths they travel in blue. They move quickly, requiring only about 30 seconds to complete a circle. In their hosts, they may be hindered from their circular path, in which case they move in a straight line.

  • 12 days from bite to illness

    Malaria - a single bite can kill

    12 days from bite to illness

    Once the parasites enter a human body, they nest for a few days in the liver. The victim cannot yet detect their presence. In the liver, they develop into merozoites, small clusters that leave the organ and attack the blood cells, causing the patient to feel sick.

  • Parasites in the bloodstream

    Parasites in the bloodstream

    The parasites require one to three days to begin multiplying within a host's blood cells. Then the blood cells break down, releasing a number of mature malaria agents and poisonous substances. This results in a fever in the host. Under the microscope, the disease is easy to diagnose. The pink-colored pathogens stand out immediately.

  • Life-savers

    Life-savers

    The best thing to do when it comes to malaria is to avoid getting bitten by mosquitoes at all. Creams and sprays that repel the insects help, as do mosquito nets, whose fine grids keep the insects out. Sleeping under mosquito nets can save lives.

  • Double protection

    Malaria - a single bite can kill

    Double protection

    Researchers have developed an especially effective type of mosquito net. Insecticide is woven into the fibers that make up the net, killing any mosquitoes that land on the net.

  • Tough measures

    Malaria - a single bite can kill

    Tough measures

    When malaria seems to be getting the upper hand, the afflicted often go for tougher solutions, like here in Mumbai, where insecticide is being sprayed en masse. A substance known as DDT is effective when sprayed against a house's walls, but it's damaging to health and the environment. DDT is long-lasting and can infiltrate an area's food chain.

  • Fast diagnoses

    Malaria - a single bite can kill

    Fast diagnoses

    Rapid tests for malaria performed on a drop of blood can detect the presence of malaria pathogens in minutes. Here the Doctors Without Borders organization investigates a boy from Mali in Africa. His test came back positive. He received medication and was healthy again two days later. But rapid tests don't always function reliably.

  • Race against time

    Malaria - a single bite can kill

    Race against time

    Medication can destroy parasites in the blood or prevent them from multiplying. But as time goes on, the pathogens are growing resistant to medications. One drug known as Chloroquin no longer works in certain regions, and counterfeit medication lacking in key components can help promote the parasites' resistance. One way around the problem is to develop new medicines.

  • Vaccine on the horizon?

    Malaria - a single bite can kill

    Vaccine on the horizon?

    A vaccination against malaria does not yet exist. Researchers are working feverishly to find a vaccine, and many studies suggest success will come soon. But uncertainty remains, especially for those in areas where malaria is common. Protecting themselves from mosquito bites remains the most effective way of dealing with the disease.

The word 'sustainability' is on everyone's lips in the lead-up to the Rio+20 conference in Brazil in June. But if development policy is to improve, mere lip service must be replaced with binding agreements.
