AMF activity update: July 2019

Against Malaria news - July 3, 2019 - 18:00

A short update on activities going on in-country this month. We will aim to post a brief update like this each month.

  • In DRC, the registration of 500,000 households in Équateur province is underway and our partner RHA is in the field carrying out independent monitoring of the registration. The distribution of 1.5 million nets is scheduled for September. A further 1.9 million nets will arrive shortly by ship in DRC for distribution in Sud Ubangi province in October. The production of 8.4 million nets is underway with these nets scheduled for distribution in Haut Lomami, Tanganyika and Haut Katanga provinces in December, January and February.
     
  • In Zambia, our partner CHAZ has just finished a round of post-distribution monitoring (PDM) activities in North-Western province and started data entry yesterday so that all records will shortly be in electronic form and ready for independent review by the AMF team. 3.0 million nets were distributed in 2018.
     
  • In Ghana, our partner World Vision is carrying out a PDM in Brong Ahafo region. Data is being collected electronically (see photos). 3.6 million nets were distributed in 2018.
     
  • In Malawi, we have put in place an agreement with the Red Cross to start PDMs later this month. 4.3 million nets were distributed in 2018.
     
  • In Guinea, 940,000 nets are arriving in a second shipment and will be distributed in three weeks, completing the distribution of 4.8 million nets
     
  • In Uganda, the 24-month PDM, i.e. monitoring that takes place 24 months after the distribution of nets in the respective districts, is continuing. Sleeping space coverage at 24 months (partial results) is 84%. 12.7 million nets were distributed in 2017/8.
     
  • In PNG, the rolling distribution of nets continues (year round activity, province by province) and PDM activity starts this week. In 2019, a total of 1.0 million nets will be distributed.
     
  • In Togo, the 18-month PDM was carried out in May using electronic devices and showed a sleeping space coverage of 88%. 2.4 million nets were distributed in 2018.
     

Why do mosquitoes choose humans?

Science Daily - July 2, 2019 - 22:45
Most of the 3,000+ mosquito species are opportunistic, but researchers are most interested in the mosquitoes that scientists call 'disease vectors' -- carriers of diseases that plague humans -- some of which have evolved to bite humans almost exclusively. One expert is trying to understand how the brain and genome of these mosquitoes have evolved to make them specialize in humans -- including how they can distinguish us from other mammals so effectively.

Botox cousin can reduce malaria in an environmentally friendly way

Science Daily - June 28, 2019 - 16:05
Researchers have found a new toxin that selectively targets mosquitoes. This can lead to innovative and environmentally friendly approaches to reduce malaria.

Malaria hijacks your genes to invade your liver

Science Daily - June 27, 2019 - 15:40
Researchers have identified more than 100 'hijacked' human genes that malaria parasites commandeer to take up residence inside their victim's liver during the silent early stages of infection, before symptoms appear. Before their work only a few such genes were known. The findings could lead to new ways to stop malaria parasites before people get sick and help keep the disease from spreading, via treatments that are less likely to promote resistance.

New high-resolution maps show how to defeat malaria

Science Daily - June 20, 2019 - 03:23
New high-resolution maps show the global burden of Plasmodium falciparum and Plasmodium vivax, the two parasites that cause the majority of malaria cases worldwide.

Human protein that aids development of malaria parasite identified

Science Daily - June 12, 2019 - 13:29
Researchers have discovered that the Plasmodium parasites responsible for malaria rely on a human liver cell protein for their development into a form capable of infecting red blood cells and causing disease. The study suggests that targeting this human protein, known as CXCR4, could be a way to block the parasite's life cycle and prevent the development of malaria.

Combating mosquito-borne diseases with bacteria

Science Daily - June 10, 2019 - 17:01
Viruses, spread through mosquito bites, cause human illnesses such as dengue fever, Zika and yellow fever. A new control technique harnesses a naturally occurring bacterium called Wolbachia that blocks replication of viruses and breaks the cycle of mosquito-borne disease, according to an international team of researchers.

US$200m milestone passed!

Against Malaria news - June 6, 2019 - 19:25

We have now reached a total raised of US$200,000,000 since AMF started and the donation that took us past that milestone was one from New York, USA!

This equates to the funding of more than 91 million nets to protect 165 million people and an expected impact of more than 30 million cases of malaria and 65,000 deaths averted.

We have also just passed 439,000 donations received, with this coming from over 121,485 people in 187 countries!

As always, our sincere thanks to everyone for their support and generosity which is both humbling and thrilling. Humbling, given the repeated support of donors and the magnitude of some of the donations, and thrilling in knowing what these donations can achieve.

I am pleased to report we have raised more than US$3,000,000 in the last month from more than 6,487 donations and this has made a dent in the funding we continue to raise to fund the need for further nets in the Democratic Republic of Congo, one of the two most malarious countries in the world, where we the potential to have a large impact on health outcomes. Donations have ranged from US$1 to US$2,000,000, and they all matter, as each US$2 buys a net and helps close the funding gap.

Dengue mosquito is Queensland's biggest threat for spreading Zika virus

Science Daily - April 23, 2019 - 15:40
Researchers have found that the dengue fever mosquito common to north and central Queensland poses the greatest danger of spreading the Zika virus in Australia. The researchers showed that not only was the dengue mosquito effective at transmitting Zika, the virus was also in the mosquitoes' reproductive organs. This finding suggests that Zika could persist in mosquito populations by females passing it to their offspring.

Sugar entering the brain during septic shock causes memory loss
