Malaria
10 Brote ActivosMalaria is a life-threatening mosquito-borne disease caused by Plasmodium parasites. It remains one of the world's deadliest infectious diseases, causing hundreds of thousands of deaths annually, primarily in sub-Saharan Africa.
¿Qué es Malaria?
Malaria is caused by Plasmodium parasites transmitted through bites of infected Anopheles mosquitoes. In 2022, there were an estimated 249 million cases and 608,000 deaths globally. Despite being preventable and treatable, malaria continues to devastate communities, particularly affecting children under 5 and pregnant women in Africa.
SÃntomas
- High fever and chills (often in cycles)
- Severe sweating
- Headache and body aches
- Nausea and vomiting
- Fatigue and weakness
- Anemia (severe cases)
- Jaundice (yellowing of skin and eyes)
- Confusion or seizures (cerebral malaria)
Transmisión
Malaria is transmitted primarily through bites from infected female Anopheles mosquitoes. These mosquitoes typically bite between dusk and dawn. Transmission can also occur through blood transfusions, organ transplants, shared needles, or from mother to unborn child.
PerÃodo de Contagio: Not directly contagious person-to-person; infectious to mosquitoes when parasites are present in blood (varies by species and treatment)
Prevención
- Take antimalarial medications when traveling to endemic areas (chemoprophylaxis)
- Sleep under insecticide-treated bed nets
- Use insect repellent containing DEET on exposed skin
- Wear long-sleeved clothing, especially after sunset
- Use indoor residual spraying with insecticides
- Eliminate standing water breeding sites
- Consider malaria vaccine in high-risk areas (children)
- Stay in air-conditioned or well-screened rooms

Nigeria Urged To Boost Local Drug Production To End Malaria
Nigeria has been urged to increase local production of anti-malaria drugs as experts warn that the country cannot eliminate the disease without ensuring consistent access to high-quality treatments. Speaking at a health programme in Lagos, experts said reliance on imports continued to weaken treatment access and exposes the country to supply disruptions. According to the World Health Organisation, Nigeria accounts for about 27 per cent of global malaria cases and nearly one in three deaths, with children under five the most affected. Executive director of Emzor Pharmaceutical Industries Limited, Uzoma Ezeoke, said the major challenge was not only the burden of the disease but also inconsistent access to treatment. She said closing the access gap required building a system that produces WHO...

Guidance for Enhanced Investigation for Suspected Autochthonous Malaria Transmission
Malaria cases with no recent travel to an endemic area (21,22) typically require an enhanced investigation. Enhanced investigation refers to public health surveillance activities beyond routine case investigation. This updated guidance focuses specifically on enhanced investigations for suspected autochthonous cases of malaria. Guidance for investigations in which malaria transmission is suspected from blood tra

The UK is a malaria science 'superpower' - and the world needs that
A wave of cuts to global health budgets in 2025 has impacted both our ability to ensure lifesaving tools reach those who need them - and our ability to develop new ones. Mosquitos and the malaria parasite have continued to build resistance to certain malaria interventions which we've relied on for years.
Climate change is shifting the habitats for some malaria transmitting mosquitoes, making them harder to track, made worse by extreme weather events. And conflict, rising across the globe, is cre

Senegal seeks private-sector support to eliminate malaria by 2030
DAKAR, June 4 (Xinhua) -- Senegal has made significant progress in the fight against malaria, with 90 percent of its health districts now in the pre-elimination phase, a senior health official said Thursday.
"Out of the country's 79 health districts, 90 percent are in pre-elimination, meaning that they record fewer than five malaria cases per 1,000 inhabitants per year," Director General of Health Youssouph Tine said at the opening of a national strategic roundtable on malaria elimination in Dak

Are mosquito nets becoming less effective against malaria?
Insecticide-treated mosquito nets, one of the most widely used and affordable tools in the fight against malaria, continue to provide strong protection against the deadly disease. However, a new international study has warned that the growing resistance of mosquitoes to insecticides could undermine the effectiveness of these nets in the future, especially in regions where resistance is already widespread.
The findings come from a comprehensive analysis of 25 studies conducted across 12 countries

Can Dogs Be Used to Detect Malaria?
Researchers at Durham University are reporting that dogs could be trained to sniff out malaria in people. While investigating ways to prevent the spread of the deadly disease, the experts found that dogs could identify the scent of malaria in samples of socks worn by infected children.
The findings could ultimately lead to the first rapid, non-invasive test for malaria.
"There is no test diagnostic that is 100% effective," Professor Steve Lindsay, study lead investigator, exclusively told Earth
