Online Tool Tracks Insecticide Resistance in Mosquitoes

IR Mapper, an interactive website, has made history as the first online mapping tool to track insecticide resistance in mosquitoes that cause malaria.

The interactive website identifies locations in more than 50 malaria-endemic countries where mosquitoes have developed resistance to the insecticides used in bed nets and indoor residual sprays.

IR Mapper incorporates the just-released World Health Organization (WHO) revised criteria for reporting insecticide resistance which is designed to detect it earlier.  

With the most comprehensive and up-to-date information, the IR Mapper helps direct which vector control tools should be deployed in areas of high resistance.  

Malaria is a deadly disease transmitted to people through infected mosquitoes. It kills a child every 60 seconds yet it is preventable and curable.

Progress has been made against the disease due largely to wide scale use of insecticide-treated bed nets and indoor residual spraying (IRS).

But the rapid spread of resistance in malaria-carrying mosquitoes to insecticides used in bed nets and sprays threatens current malaria control efforts.

Resistance among Anopheles malaria vectors has been reported in 64 countries, with parts of Sub-Saharan Africa and India of greatest concern.

“Deployment of the most appropriate insecticide based vector control interventions including nets and IRS needs to be informed by up-to-date data on insecticide resistance in the malaria vector species,” said Dr. Nabie Bayoh, an entomologist at KEMRI/CDC in Kisumu, Kenya.  

“Until now, data has been scattered throughout different databases and has come from a variety of sources.  This has made prompt decision-making difficult. IR Mapper has helped to address this” he added.

IR Mapper consolidates published data on insecticide susceptibility and resistance mechanisms from 1959 to 2012.

It includes reports from the President’s Malaria Initiative, National Malaria Control Programmes and other reputable institutes.

Resistance is usually measured by putting mosquitoes in a tube lined with insecticide-treated paper. Mosquitoes land on the paper and absorb the insecticide – some may die and some may survive. A population is considered susceptible if almost all die.

Until recently, resistance was confirmed by survival of more than 20 percent in this test.

The new guidelines from WHO reduced this threshold value to 10 percent, meaning that resistance will be reported earlier. This change is an indication of the concern insecticide resistance is causing globally.

IR Mapper data aligned with the new WHO thresholds is presented in a user-friendly format on interactive maps.

The mapping function allows filtering and projection of data based on a set of user-directed criteria. For instance, users can examine the resistance status of single or multiple Anopheles species to one or more insecticides within their region of interest.

This can be the basis for a “go” or “no go” decision on a particular insecticide for deployment on nets or in sprays. Data can also be viewed for specified time periods, to identify any existing trends in resistance over time.

Data consolidation for IR Mapper was conducted by Vestergaard Frandsen and KEMRI/CDC.

Jumia Expands Nationwide Footprint, Deepens Reach Across Underserved Nigerian Cities

Published

Kindly share this post

e-commerce company, Jumia Nigeria, has announced a significant expansion of its logistics and pickup network across Nigeria, extending its reach into underserved regions and strengthening access to e-commerce services for millions of consumers.

The expansion, executed during the first quarter of 2026, marks a deliberate shift toward upcountry growth, with new and expanded operations across Northern Nigeria, including Kebbi, Sokoto, and Kaduna, while also strengthening presence in strategic cities like Zaria. The move is designed to close long-standing coverage gaps in high-potential areas and bring its services closer to more customers.

According to the company, the expansion reflects a convergence of customer demand, infrastructure strategy, and long-term market development, as more Nigerians outside major urban centres seek reliable access to digital retail.

“We are seeing a structural shift in where demand is coming from. What this expansion does is align our infrastructure with that reality. By extending our network deeper into the country, we are not only improving service delivery, but we are also unlocking new demand, enabling more sellers to participate in the digital economy, and building a more inclusive retail ecosystem that reflects the true scale of the Nigerian market,” said Temidayo Ojo, CEO of Jumia Nigeria.

The rollout includes a significant increase in pickup stations and delivery touchpoints across both established and emerging cities. Existing urban centres such as Lagos, Ibadan, Abuja and Port Harcourt have seen network density increase, while new and previously underserved locations are being integrated into Jumia’s logistics grid. This broader footprint is supported by investments towards parcel distribution centres, designed to decentralise inventory flow, reduce delivery time, and optimise operating costs across regions.

As part of the expansion, Jumia has also strengthened its logistics partnerships and delivery capacity, enabling more efficient last-mile fulfilment while creating income opportunities for a growing network of logistics partners and JForce agents. The company notes that these investments are critical to sustaining scale as order volumes increase across a more geographically diverse customer base.

Looking ahead, Jumia plans to extend its expansion into the South-East and South-South regions ahead of the peak retail season, further increasing its national coverage and reinforcing its position as a leading e-commerce platform in Nigeria.

RHUCE Taps Into Africa’s $3Bn Creator Economy with New Monetisation Platform

RHUCE, a new social platform designed for African creatives, has officially launched today, introducing a new model for how creators across the continent can turn their skills, learning, and content into income.

RHUCE Taps Into Africa’s $3B Creator Economy with New Monetisation Platform

RHUCE

As Africa’s creator economy, estimated at over $3 billion, continues to grow, millions of young people are building digital skills but struggle to convert them into sustainable opportunities. RHUCE aims to bridge this gap by combining professional identity, creator monetisation, and opportunity discovery in a single ecosystem.

“Across Africa, talent is everywhere, but opportunity is fragmented,” said Simeon Ifeoluwa Adeyanju, CEO of RHUCE Limited. “Creators are learning, building, and sharing their work, but they lack a structured way to turn that into visibility, credibility, and income.”

Unlike traditional platforms that prioritise virality or finished work, RHUCE enables users to document their growth in real time, transforming their learning journey into a living portfolio.

“We believe your journey is your greatest asset,” Adeyanju said. “On RHUCE, your growth becomes your portfolio, your consistency builds your credibility, and opportunities can discover you based on what you’re becoming, not just what you’ve done.”

The platform introduces a shift from application-based hiring to discovery-driven opportunities, where creators are matched with jobs, gigs, and collaborations based on their evolving skills and documented progress.

“Instead of chasing opportunities across WhatsApp groups, DMs, and multiple platforms, we’ve built a system where you can post once and be discovered continuously,” he added.

RHUCE also provides monetisation tools that allow creators to earn through digital products, paid learning content, and brand-sponsored campaigns, unlocking new income streams within Africa’s fast-growing digital economy.

With over 60% of Africa’s population under 25, the platform positions itself as infrastructure for the continent’s next generation of talent.

“RHUCE is not just a platform for finished professionals,” Adeyanju said. “It is for people becoming something. Our goal is simple: help Africans turn learning into opportunity, and opportunity into income.”

Kaspersky Warns of Digital Medicine Risks on the Occasion of World Health Day

Published

on

On World Health Day, Kaspersky warns of risks tied to the digitisation of healthcare and use of telemedicine. Recent incidents show that medical services can be breached, and as a result, medical records may be leaked and then traded on the dark web.

The operations of healthcare services can get disrupted. Another aspect is that healthcare platforms may share user data with third parties that handle it irresponsibly.

Telemedicine has moved from a convenience to a core part of healthcare delivery, but its security model has not kept pace with its adoption, and the risks are not theoretical. Recent incidents highlight how real these risks have become.

In 2023, it was disclosed that Cerebral, a major telehealth provider focused on mental health services, had been sharing sensitive patient data – including mental health assessments, intake information, and personal identifiers – with third-party platforms such as social media and advertising networks. Millions of users were affected over several years.

More broadly, incidents in 2025 illustrate a different but equally critical risk – large-scale disruption of digital healthcare infrastructure. The breach of the ManageMyHealth patient portal exposed sensitive medical records of more than 120,000 patients, while the attack on SimonMed Imaging compromised over a million records and led to ransomware demands. These cases show that both telemedicine platforms and the broader digital healthcare ecosystems are increasingly targeted by attackers.

In parallel, scam campaigns focusing on medical topics are evolving, inviting patients for check-ups or follow-up consultations. Often the domains of the alleged “medical services” websites were created just a few weeks ago, links to the social media accounts on their pages are not working, and the Terms of Use and Privacy Policy pages are absent.

At the same time, these pages request users’ personal information, including photos of documents and even photos of parts of the body that need medical attention. Such websites often try to convince users with branding, fake doctor profiles, and urgent calls to action.

Users risk submitting sensitive personal data that can be either sold on the dark web, be used for identity theft, or subsequently used in more sophisticated attacks in the future that are targeted specifically at them for further data extortion.

To safeguard sensitive data, use a reliable security solution with an AI-powered anti-phishing component which prevents clicking on malicious links.

“The digital healthcare experience is transforming access to care, but it is also expanding the attack surface in ways many users underestimate. Medical data is highly valuable and actively traded on the dark web, making patients a prime target for fraud and targeted phishing.

“At the same time, health-related scams exploit urgency and trust, using fake consultations or discounted offers to trick users into sharing sensitive information. Patients should approach digital healthcare with the same caution as financial services – verifying providers, avoiding unsolicited links, and understanding how their data is used. Security and privacy must become a core part of the digital healthcare experience,” comments Anna Larkina, Web Content and Privacy Analysis Expert at Kaspersky.
