Healthcare systems across Africa are “far from ready” to cope with a fresh surge of coronavirus infections, with vaccine deliveries at a near standstill and cases surging in many countries, the World Health Organization (WHO) has warned.
“Many African hospitals and clinics are still far from ready to cope with a huge rise in critically ill patients,” WHO regional director for Africa, Matshidiso Moeti, said on Thursday.
Africa has officially registered more than 4.8 million cases and 130,000 deaths, according to the WHO, representing 2.9 percent of global cases and 3.7 percent of deaths.
According to a survey conducted by the WHO in May, the essential health facilities and personnel required to manage critically ill COVID-19 patients are grossly inadequate in many African countries.
Of 23 countries surveyed, most had less than one intensive care unit bed per 100,000 population and only one-third had mechanical ventilators. In comparison, countries like Germany and the United States have more than 25 beds per 100,000 people.
“Treatment is the last line of defence against this virus and we cannot let it be breached,” Moeti stressed, calling for better equipment for hospitals and medical staff.
In recent weeks, the continent has seen a rise in infections. South Africa, officially the most affected African country, has tightened health restrictions and now has more than 1.6 million cases and 56,439 deaths.
In the capital of the Democratic Republic of the Congo (DRC), Kinshasa, the WHO detected an “exponential rise” last month in cases that mirrored a “clear deterioration” in the wider province.
The DRC Health Minister Jean-Jacques Mbungani said that the country was experiencing a new wave of infections.
“I officially announce the onset of the third wave of the COVID-19 pandemic in our country, with Kinshasa as its epicentre,” Mbungani told reporters.
A low vaccination rate and haphazard observance of recommended hygiene practices were among the reasons for the rising infection rate, he said….
As they grow, solid tumors surround themselves with a thick, hard-to-penetrate wall of molecular defenses. Getting drugs past that barricade is notoriously difficult. Now, scientists at UT Southwestern have developed nanoparticles that can break [...]
In an article recently published in the journal Talanta, researchers demonstrated a new approach to enable the specific detection of biomarkers in human tear by employing an aptamer-based graphene affinity nanosensor. The ability to detect [...]
Selenium (Se) is an essential element found in aquatic feeds that promotes the proper development, wellbeing, and fitness of marine animals. Selenium can be transformed into nanomaterials that are more easily accessible, absorbed, and consumed by [...]

Would you like to help in some research on the regulation of what future AI-driven nanomedicines should look like? If so, researchers at the University of Bristol are looking for volunteers to discuss ethical [...]
In an article recently published in the journal Applied Surface Science, the researchers synthesized green fluorescent carbon dots (G-CDs) from 3,5-diaminobenzoic acid and citric acid. The as-prepared G-CDs were used to target the nucleolus and [...]
Doxorubicin (DOX) is a powerful anti-cancer medication, and efforts have been made to design nanostructures for delivering it to cancerous cells. The nanostructures increase the cytotoxic effects of DOX on cancerous cells, while reducing the negative effects [...]
