 KENYAN RESEARCHERS TAKE MALARIA GENOMIC RESEARCH INTO FIELD

.....as half the world was at risk of malaria, with 247 million cases and 619,000 deaths reported in 2021 by WHO.


By Alfonso Kasongo

Researchers at the KEMRI-Wellcome Trust Research Programme in Kenya are moving genomic research from the laboratory into the field, by using molecular epidemiology as part of routine malaria surveillance to better understand and track mutations in parasites.


The team aims to collect 300 blood spot samples from people in each of 14 Kenyan counties over the coming year, and establish a national data repository to inform policy decision-making for the National Malaria Programme.

The World Health Organization’s (WHO) World Malaria Report 2022 shows that half the world was at risk of malaria, with 247 million cases and 619,000 deaths reported in 2021. Africa accounts for 96% of all malaria deaths. It is vital for health officials to understand how parasites mutate, and how to detect and vaccinate against them.

Identifying mutations will help researchers develop diagnostic tools that accurately identify new variants. Detecting parasites with mutations in the lab can be done with next-generation sequencing technologies within 7 to 14 days.

Genomics has an important role to play in the surveillance systems needed to help health authorities put strong early warning systems in place.

Bringing awareness of malaria epidemiology research and surveillance systems to public health officials is strengthening Kenya’s efforts to eradicate malaria, along with ongoing programmes such as the scaling up of the malaria vaccine roll-out earlier this year.

This work will also contribute to international efforts to combat malaria, as the researchers regularly engage with and share findings with peers across Africa, through organisations such as the Pathogens Genomic Diversity Network Africa (PDNA).

ZAAB QUESTIONS GOVERNMENT'S SILENCE ON PBR BILL

  ZAAB QUESTIONS  GOVERNMENT'S SILENCE ON PBR BILL  By Alfonso Kasongo  A collaborative network of concerned citizens, civil society groups, faith and farmer-based organisations, working together to strengthen the growing movement for agroecology and food sovereignty has questioned government's failure to avail the proposed new Plant Breeders Rights (PBR) Bill.  Zambia Alliance for Agroecology and Biodiversity (ZAAB) maintains that controversial Bill is inappropriate for the country and must not be enacted as it aligns the country to the International Union for the Protection of New Varieties of Plants (UPOV) 1991 standards. The Consortium fears that once proposed PBR Bill is enacted in its current form, the new seed law may trigger price increase and corporate capture of seeds, as well as  country's food system.  The Alliance argues that government through the Seed Control  Certification Institute SCCI  has never presented the actual changes...

ZAMBIA LISTED AMONG 34 COUNTRIES WORLDWIDE THAT EXPERIENCED DIGITAL AUTHORITATIVE RULE

Image
  By Alfonso Kasongo  The shutdown of internet to block access to social media during the 2021 general election has earned Zambia a slot among 34 countries worldwide that experienced digital authoritative rule last year. According to a research conducted by Keep It On ,182 internet shutdowns from 34 countries were last year recorded and are documented. Sadly 19 of the 34 countries are African countries, an indication of the return of the digital authoritatism. The report  discloses that the Zambian authorities shutdown the Internet during the the tight 2021 general election to block access to social media platforms which  include among others WhatsApp, Facebook, Twitter and Instagram.   The report however ,suggests that the country experienced digital authoritative rule which undermined the democracy of the country.    It further notes with pleasure that the shut down was fought swiftly by Chapter One Foundation through the court of law and that the Hi...

ZAMBIA'S CLIMATE FINANCING UTILISATION LACKS TRANSPARENCY, ACCOUNTABILITY

ZAMBIA'S CLIMATE FINANCING UTILISATION LACKS TRANSPARENCY,  ACCOUNTABILITY ...hence prone to corruption risks,posing threats against building climate change resilience, TIZ report reviews. By Alfonso Kasongo Zambia's quest to remain climate change resilient might veer off course, if gaps such as weak climate regulatory frameworks, corruption risks and lack of transparency in the management of climate financing remain unaddressed. Ànd tackling of how the country supports mitigation and adaptation to climate change remain critical to building resilience to the worst effects. Climate resilient is generally defined as successfully copying with and managing the impacts of climate change while preventing those impacts from growing worse. This year's unprecedented global temperatures and stark devastating of climate change stress the urgency requirement for Zambia and many other countries to build climate resilience, hence the need for strong regulatory framework and transparency ...
