World Africa's Covid patients 'dying from lack of oxygen'
The Pandemic Has Undone South Africa’s National Parks
Without tourism, the funding that sustains some of the world’s most treasured wildlife has atrophied.These birds usually nest on hard-to-reach offshore islands, but at Boulders a cordon of residential blocks shields the beach and the surrounding dunes from land-based predators like the caracal lynx, and the penguins feel safe enough to breed. Here you can hear their braying calls, smell their acrid guano, and stroll within a few yards of doting parents feeding their fluffy brown young. You can even swim with the birds in a bright-watered cove.
Many African countries are facing a "growing crisis" of severe oxygen shortages which is leading to preventable deaths, international health agencies have warned.
A doctor in Somalia's semi-autonomous region of Puntland told the BBC that between five and 10 of his Covid patients were dying because of a lack of oxygen almost every day.
"These would all be preventable deaths if we had adequate oxygen," said Dr Jama Abdi Mahamud at the government-run Gardo General Hospital.
How the coronavirus Delta variant rampaged through India before spreading across the globe
As Delta rampaged through India undetected, doctors were confounded by the sheer scale of the virus's spread. This is how the COVID-19 variant fuelled a calamitous surge in cases before slipping beyond the country's borders.Daily confirmed infections were in the low hundreds and serological surveys, which detect COVID-19 antibodies in the blood, suggested more than half the city's population had been infected after overcoming three surges.
There are no official figures available showing a rise in preventable deaths, but many low-income countries are struggling to access oxygen supplies amid surging coronavirus cases, and limited or no access to coronavirus vaccines.
Every Breath Counts, a coalition of global health campaigners, say 18 low-income countries are currently dealing with oxygen shortages or are at risk of facing the crisis, with most of those being in Africa.
"The G20 Global Health Summit leaders didn't mention oxygen at their meeting in May, but the G7 has now signalled there will be financial support for oxygen," said Leith Greenslade, co-ordinator of the coalition.
Jessica Winn, head of pneumonia support hub for Save the Children, said the need for oxygen in these countries was high and urgent.
global warming: lakes append

LP / Olivier BOITET Do not rely on the apparent placidity of their surface waters. Because, without making waves, lakes suffocate. Victims of the global warming, they run out at a disturbing rate for lack of oxygen.
"Now that a third wave of the pandemic has arrived in Africa, populations are again at risk. Since 1 June 2021, the oxygen needed to treat Covid-19 patients in Zambia has increased five-fold to 50,000 cubic meters, and three-fold to 12,000 cubic meters in the Democratic Republic of Congo.
"Demand for oxygen to treat Covid-19 patients is steeply rising in Zimbabwe."
A study published in the Lancet last month suggested more than half of the Covid patients that died in 64 hospitals in 10 African countries were not given oxygen.
'No oxygen plants'
Dr Mahamud said that during the second wave in Somalia up to 25 people were dying each day in his hospital because of a lack of oxygen: "It is really stressful to work in this condition."
According to World Health Organization (WHO), of the 14,823 confirmed coronavirus cases in Somalia as of 16 June, 775 people have died.
Health professionals say the real figure could be many times higher because there is no proper reporting mechanism, and many deaths occur in villages.
SA lower house passes assisted dying laws
The South Australian lower house has passed by 33 votes to 11 a bill to legalise voluntary assisted dying in the state.The House of Assembly met on Wednesday evening to consider a number of amendments to the original bill, which had comfortably passed the upper house last month.
"There are around 750 hospitals and primary health centres across Somalia which urgently need more than 1,400 oxygen concentrators, but they have received less than 300," said Dr Joseph Serike, senior health technical specialist with the Save the Children in the capital, Mogadishu.
Government officials admit it is a growing challenge.
"No government-run hospitals have oxygen plants. Only three private hospitals in the capital, Mogadishu, have them," said Dr Ubah Farah Ahmed, director of family health department at Somalia's health ministry.

In neighbouring Ethiopia, health officials said some government hospitals had oxygen plants but they are overwhelmed because they now need to supply to other hospitals too.
"And because of the high production pressure, the plants break down worsening the shortage," said Dr Menbeu Sultan, chair of Ethiopian Society of Emergency Medicine Professionals.
COVID-19. The Regeneron and Roche Cocktail would reduce mortality in patients without antibodies

"miracle" treatment vailed by Donald Trump, the combination of AGN-COV2 monoclonal antibodies seems effective for patients who have not yet developed coronavirus antibodies. A British study shows that it would prevent developing serious forms of the disease.
"The shortage is severe in remote and very poor places because they have no production of their own.
"And lorries carrying oxygen cylinder have to travel hundreds of kilometres to reach such places and in some cases it is too late for patients who urgently need the gas."
As of 16 June, Ethiopia has seen 274,346 confirmed Covid cases and 4,250 deaths.
During the last major wave between April and May, Ethiopia needed around 15,000 cylinders of oxygen in a day, according to an oxygen-need tracker updated by Path, an international non-government organisation working in health sector.
It shows the need is now down to 1,200 cylinders per day but experts with the tracker said their calculation is based on reported Covid cases and most of the cases in the country go unreported.
In DR Congo, the demand has gone up to nearly 2,000 cylinders per day from less than 500 earlier this month, according to the tracker.
Experts say many of the lowest-income countries in Africa, like very poor countries elsewhere, lack commercial oxygen production facilities, which could then potentially divert supplies to hospitals to help during emergencies.
As a result, very few hospitals can supply high-flow oxygen that critical Covid patients need, health experts say.
Elective surgeries cancelled for two weeks for some patients by Australia's largest public hospital provider
Australia's largest public hospital provider — Brisbane's Metro North Hospital and Health Service — cancels elective surgeries for some patients for a fortnight to deal with bed shortages. It comes as Queensland's medical leaders said the system was at breaking point with a lack of beds and staff, and inadequate health funding dating back more than 30 years.A memo from Brisbane's Metro North Hospital and Health Service (MNHHS) chief executive said hospitals have been experiencing "increased demand" over the past weeks.
"In our whole country, only one hospital has the capacity to treat at a time more than 10 patients needing high-flow oxygen and their Covid unit is usually full," said Dr Sarah Wandia, who works in Maua Methodist hospital in Kenya.
"We lost two patients from our hospital waiting for the space in that unit.
"Our hospital's current oxygen plant has the capacity of producing 45 litres of oxygen while one Covid patient can use 15 litres of oxygen leaving a precarious amount to care for premature babies, intubated patients in the operation theatre and in the accident and emergency department."
Health experts say it took a year for oxygen supply to be recognised as an essential medicine in the global strategy to treat Covid patients.
"The impending crisis was a blind spot for the global health community for a year," said Ms Greensdale of Every Breath Counts.
International financing agencies like the Global Fund say they have now made fast-track funding for oxygen available to some lowest income countries including The Gambia, Kenya, Malawi and Tanzania in Africa.
"With the help of donor agencies, we will soon install 10 oxygen plants in some government hospitals," said Somalia's Dr Ahmed.
