Meet the MESA Correspondents that will cover the 2021 ASTMH Annual Meeting

November 4, 2021 - 12:49 -- MESA Alliance

The MESA Correspondent volunteers report on the latest in malaria research from conferences around the world. The synopses are shared online, enabling people who could not attend the meeting or missed a particular symposia to read about the latest advances. The MESA Correspondents Program is a collaboration between MESA and the conference organizers.

Global technical strategy for malaria 2016-2030, 2021 update 19 July 2021

November 2, 2021 - 15:11 -- Malaria World

The Global technical strategy for malaria 2016–2030 was adopted by the World Health Assembly in May 2015. It provides a comprehensive framework to guide countries in their efforts to accelerate progress towards malaria elimination. The strategy sets the target of reducing global malaria incidence and mortality rates by at least 90% by 2030.

Do vaccines increase Malaria and Covid ?

October 30, 2021 - 16:23 -- Pierre Lutgen

The efficacy of vaccines is a complex issue and sometimes long range effects may be disastrous.

The situation is dramatic for the RTS,S vaccine which protects only against sporozoites but does not induce clinical immunity against blood-stage parasites. The vaccine showed evidence of 35,9% efficacy in the first year after vaccination, but efficacy fell to 2.5% in the fourth year. The cohort with a high exposure index even showed a negative efficacy during the fifth year, i.e. an higher level of infection

Podcast: New apicoplast findings change how scientists perceive parasite survival

October 27, 2021 - 08:06 -- Johns Hopkins

Podcast #4 | 29 October 2021: New research into the role and function of the apicoplast, a plant-like structure within the malaria parasite, has changed scientists’ perceptions of how the parasite survives.

Time for action: about malaria, poverty and travel

October 19, 2021 - 13:58 -- Malaria World

 

As a community of malaria professionals, we are committed to ridding the world of a disease that causes suffering in many low and middle income countries (LMIC). At the same time, our collective air travel contributes to climate change that has major health consequences and disproportionally impacts LMICs and vulnerable groups. Here, we propose the ‘Thoughtful Travel’ approach to improve the sustainability of our work.

Podcast: Malaria parasites mutate and have ability to evade RDTs, rapid diagnostic tests

October 14, 2021 - 20:19 -- Johns Hopkins

Podcast #3 | 15 October 2021: Results from a large study in Ethiopia showed that P. falciparum malaria parasites have mutated and have the worrisome ability to avoid being detected by the widely used RDTs.

P. vivax Malaria Recurrence and Human Nature

October 13, 2021 - 17:03 -- Miles Markus

People who did not believe the non-reinfection, non-circulating merozoite-related P. vivax malarial recurrence concept [explained here: https://doi.org/10.2147/TCRM.S269336] are now quietly starting to echo it.

However, it is interesting to note that this has directly or indirectly been done by the authors of some papers while studiously avoiding inclusion of any reference to where the idea (prediction) came from in the first place, thereby revealing their true colours.

WHO - Mekong Malaria Elimination: epidemiology summary, volume 14, April–June 2021

October 12, 2021 - 14:52 -- Malaria World

From April to June 2021, countries in the Greater Mekong subregion (GMS) reported 12 454 malaria cases.

Cambodia
Cambodia reported 596 cases, a 74% decrease compared to the same time period in 2020. P. falciparum + mixed cases and P. vivax constituted 10% and 90% of cases, respectively.

China (Yunnan Province)
Yunnan reported 47 P. vivax cases and 0 P. falciparum + mixed cases. Among those, no indigenous cases were reported.

NEWS: WHO recommends groundbreaking malaria vaccine for children at risk

October 6, 2021 - 17:55 -- Malaria World

Historic RTS,S/AS01 recommendation can reinvigorate the fight against malaria

6 October 2021 News release Geneva

The World Health Organization (WHO) is recommending widespread use of the RTS,S/AS01 (RTS,S) malaria vaccine among children in sub-Saharan Africa and in other regions with moderate to high P. falciparum malaria transmission. The recommendation is based on results from an ongoing pilot programme in Ghana, Kenya and Malawi that has reached more than 800 000 children since 2019.

Saponins, tuberculosis and malaria

October 4, 2021 - 16:58 -- Pierre Lutgen

A team of medical doctors in Nord Kivu discovered that Artemisia afra infusions were very efficient in the therapy of tuberculosis patients.

   Daddy B, Lutgen P, Gisenya P. Breakthrough against tuberculosis: high efficacy of Artemisia afra infusions. Pharm Pharmacol Int J. 2021;9(2):58‒62. DOI: 10.15406/ppij.2021.09.00328

Some other plants are also known to have an antituberculosis effect. For example, Entada abyssinica, a Fabaceae, rich in saponins was found to be be very efficient in vitro against Mycobacterium tuberculosis.

Podcast: Preventing Malaria During the Rainy Season

October 1, 2021 - 19:08 -- Johns Hopkins

Podcast #2 | 01 October 2021: A new trial investigates whether drugs or vaccines – or a combination of both – are most effective at preventing malaria during the seasonal period, and the WHO’s malaria director considers the current situation in malaria eradication.

A cry for help!

September 29, 2021 - 18:59 -- Ingeborg van Schayk

 

Today you will not receive a regular MalariaWorld Newsletter. Why? Because I would like to ask your attention for an urgent matter.

We have to build a new MalariaWorld platform because the current platform is 12 years old and it won’t last forever. We need € 20.000 to make this happen. I am convinced that with your help we can. That's why I need to ask you for a generous donation.

VectorBase: Seeking Anopheles gambiae complex population dynamics data

September 24, 2021 - 17:10 -- Malaria World


Understanding the population dynamics of Anopheles gambiae, the dominant malaria vector across Africa, requires time series data on mosquito abundance at different sites. This project seeks to collect raw trap count data from many different contributors, collate it in a public database, and make it available for visualization and download via an unrestricted, open access web interface. In this way, a little data from many diverse contributors can add up to a comprehensive resource for all.

Plasmodium vivax: Relapses or Recrudescences?

September 24, 2021 - 03:10 -- Miles Markus

For the past 40 years, we have readily ascribed recurrences of Plasmodium vivax malaria to hypnozoite activation.

But during this 40-year period, we have been completely unaware that there are extremely large numbers of merozoites (compared to only a few hypnozoites) hiding outside the peripheral bloodstream – not only sequestered but happily multiplying extravascularly in tissues.

Partnerships - what MalariaWorld can do for you

September 10, 2021 - 07:36 -- Ingeborg van Schayk

At MalariaWorld we work with partners. One of the advantages of partnering with MalariaWorld is that we use our 20+ years of knowledge, skills, and experience as well as our entire MalariaWorld network to get information across to more than 11.000 malaria professionals in 140 countries. How do we do that? Well, sometimes we just partner for a certain event such as with MIM, PAMCA, or the First Malaria World Congress.
