When Caroline Wangamati was touring a rural Kenyan hospital in 2018, the medical doctors shared that two younger moms would probably be lifeless inside hours.
Their hemoglobin ranges have been catastrophically low — an indication of life-threatening anemia. The typical response could be a blood transfusion, however the native blood financial institution was empty.
So Wangamati, the primary girl of Bungoma County on the time, frantically referred to as the regional blood heart — 85 miles away — to have them ship some models.
The supply arrived just a few hours later. “I was very proud of myself,” Wangamati tells NPR. “After the blood came in and we transfused the women, I went to see the medical superintendent and was saying, ‘I’m so glad we got them this blood because these two women would have died.'”
“He told me, ‘But Ma’am, you didn’t go to the pediatric ward. We had more than nine patients that needed blood.'”
Across the world, lots of of tens of millions, if not billions, of individuals dwell in areas the place there’s not sufficient blood in at the least 75% of medical circumstances. Last month, a coalition of 27 medical doctors, researchers, and affected person advocates coined the time period “blood desert” in a Lancet Global Health paper final month, hoping to construct consciousness and share options.
In a blood desert, what are usually highly treatable conditions — trauma, sickle cell anemia or postpartum bleeding — typically develop into lethal. “Blood is a life-saving drug; it’s considered essential medicine,” says Dr. Nobhojit Roy, a retired rural surgeon from India. But almost each nation in sub-Saharan Africa and South Asia is struggling with deficits, in keeping with a 2019 Lancet Haematology research.
Given such shortages, physicians typically have solely two decisions when their sufferers undergo main bleeding, in keeping with Dr. Nakul Raykar, a trauma surgeon at Brigham and Women’s Hospital. “One is to attempt to do something, knowing full well you’re not going to succeed without blood transfusion,” he says. “And your second option is to tell the patient, ‘Nope, sorry, we can’t treat you here. But you can go to the district hospital, which is two to four hours away,’ knowing full well they’re not going to make it.”
Global well being businesses have lengthy championed blood banks as the answer. But that assumes there’s cash to construct high-quality storage services and dependable sufficient electrical energy to keep up refrigeration, to not point out the logistical experience to recruit donors, display screen blood and distribute models on time. So whereas there are dozens of blood banks in massive cities like New Delhi or Nairobi, there are basically none in rural Bihar or Turkana County, says Raykar. “We’ve waited decades for enough blood banks to be built, and we’re going to be waiting several decades more.”
Raykar and his crew recognized the three most progressive options for the world’s blood deserts within the Lancet Global Health. Whether there’s the political will to handle this disaster, nonetheless, stays unsure, given the rigidity of HIV-era rules and the invisibility of sufferers in danger.
Walking Blood Banks and HIV Controversy
There’s a controversial — typically unlawful — workaround: “walking blood banks,” the place medical doctors do not retailer blood in fridges however depend on drawing blood from neighborhood members.
Health-care employees establish these folks and, throughout instances of disaster, mobilize them to donate their blood. After the donated blood is examined for HIV, syphilis and different transmissible ailments on the spot, it’s immediately transfused to the affected person — no blood financial institution required.
In particularly dire circumstances, health-care employees generally roll up their very own sleeves. “This mother was dying, and her doctors gave three pints of their own blood. And they watched the mother literally come back from death,” recounts Wangamati, who can also be considered one of Kenya’s 4 apponted “Blood Ambassadors,” elevating public consciousness across the situation. “This practice is done in almost every hospital in the country; it’s just that they can’t shout about it — because it’s illegal,” she says.
Indeed, Kenya is considered one of many low- and middle-income international locations that banned strolling blood banks within the Nineteen Nineties and 2000s — the results of HIV activists calling for zero tolerance for blood-transmitted circumstances and corresponding strain from the World Health Organization and the U.S. President’s Emergency Plan for AIDS Relief, in keeping with Raykar and a number of other different international well being specialists.
In India, for instance, the National AIDS Control Organization took over blood transfusion obligations from the Ministry of Health in 1996. Three years later, the federal government banned walking blood banks within the identify of security.
“Their sole mission is zero transmission of HIV,” says Raykar in regards to the National AIDS Control Organization. “They have to report the metrics of how many transfusion infections happened per year, not the number of people who died because of lack of blood — that’s completely ignored.” Dr. Shobini Rajan, chief medical officer of India’s National AIDS Control Organization, declined to remark.
“There’s a constant tension between access and safety,” Raykar continues. At native clinics, speedy diagnostic checks may display screen strolling blood financial institution donations for HIV and different transmissible ailments with 98-99% accuracy. But in its latest guidance from April 2023, WHO strongly recommends towards these checks and strolling blood banks — exterior of an “acute emergency.” A WHO spokesperson defined in an announcement to NPR: “While the transfusion of blood collected from donors to patients can save lives, it involves risks itself and could cause serious consequences, even death of patients.” PEPFAR didn’t reply to a request for remark.
What frustrates Roy is that, by framing strolling blood banks as an exception, WHO’s steering leaves their utility “rather vague, rather open to interpretation” — with out acknowledgement that blood deserts themselves are in a state of emergency.
“Extreme blood scarcity in much of the world is not an impending, catastrophic event, but the current status quo,” says Roy. But imposing federal legal guidelines, police will punish medical doctors for turning to strolling blood banks in emergency conditions, when sufferers could also be on the point of demise.
In reality, 4 physicians interviewed for this story described how fellow health-care employees have been arrested for utilizing strolling blood banks. “They put their jobs on the line to save a life,” says Wangamati, who skilled in well being coverage on the London School of Economics. “Can we have the boldness to look at walking blood banks as a solution for those times when blood is not there?”
Yetmgeta Abdella, a transfusion drugs physician and the rapid previous medical officer for blood on the WHO Regional Office for the Eastern Mediterranean, defends the worldwide well being company’s place. He emphasizes that it is not so easy to show to strolling blood banks given accuracy points with speedy diagnostic checks. “In countries in Africa and Asia, the environmental conditions are so diverse and sometimes hostile, so if you don’t have the right storage conditions for the test kit, you will not have the correct result,” says Abdella.
Then comes the difficulty of deploying these checks in rural settings the place laboratory personnel don’t essentially have the expertise of technicians in bigger regional facilities. Abdella factors to a research he revealed within the Journal of Laboratory Physicians, the place throughout ten speedy diagnostic checks utilized in Pakistan, accuracy for hepatitis B and C detection ranged from 65-85%.
A former WHO technical officer himself, Roy agrees that security is vital and that extra analysis is required to validate efficiency in blood deserts. However, he additionally worries that security considerations have been overly sensationalized to the neglect of entry, pointing to how the U.S. military has adopted strolling blood banks as a protected, efficient transfusion technique in struggle zones. “What we live through every day in these blood deserts is nothing short of that,” Roy says. “How many people need to die before you say that this is war?”
Blood supply by drone
Given the controversy round strolling blood banks and the extent of the scarcity, international well being specialists have explored different methods to additional increase entry to blood.

Perhaps probably the most flashy innovation has been drone-based supply: flying blood to hard-to-access rural areas. Ambulances may make these deliveries in some circumstances, says Roy, however they’re typically too slow in emergency conditions, struggling to navigate poor roads and troublesome terrain.
These drones have thus been piloted in locations like Meghalaya, a state in northeastern India tucked into the Himalayas, and Rwanda, the place over 80% of the inhabitants is rural. Blood that used to take 2-3 days to reach in distant Meghalaya can now attain these clinics inside four hours, in keeping with Raykar.
In this hub-and-spoke mannequin, the drones are launched from a handful of blood banks in main cities, zooming via the skies at 75 miles per hour. “It’s pretty much like Amazon,” says Roy. “You stop trying to have retail stores everywhere; you just have a big hub and a highly efficient delivery system.”
While Raykar is worked up about all methods to get blood to suppliers, he acknowledges that drone-based deliveries aren’t a magic bullet since they can not deal with a scarcity of provide. Already, WHO recommends a minimal of 10 models of blood donated for each 1,000 neighborhood members, however low-income international locations do not even attain half that quantity. And then there’s the possibly prohibitive start-up investments for any drone-based supply program — over $4 million within the Rwanda instance.
“These companies are flying blood from places designed for blood collection, but ultimately, we still need more blood locally,” Raykar says.
An answer throughout surgical procedure
Beyond drones, some international well being specialists have turned to autotransfusion, the place surgeons acquire blood pooling inside sufferers’ our bodies, use a tool to wash it up after which return their blood.
“Instead of throwing it away and running around looking for a replacement, we can easily just pick that blood and give it back,” says Dr. Asma Awadh, an infectious illness doctor from Kenya who’s been engaged on autotransfusion since 2018.
Since this blood comes from sufferers themselves, medical doctors needn’t display screen for transmissible ailments or test for matching sorts. That saves time and money. There’s an oblique profit as nicely: If medical doctors recycle blood of surgical sufferers, they’ll allocate extra donor provides to sufferers with leukemia, sickle cell and different non-surgical situations requiring transfusions.
The thought behind autotransfusion is not new, with the primary documented case in 1914. A German physician took blood from girls struggling miscarriages, filtered it via gauze and transfused it again. While commonly used right now within the U.S. with the $20,000 Cell Saver system, autotransfusion hasn’t taken off in low- and middle-income international locations, Awadh says, due to the excessive price of most autotransfusion units, restricted coaching in these methods and considerations over sufferers’ blood being contaminated throughout an operation.
But there are methods to get across the value barrier. Awadh works as a coach for the medical gear firm Sisu Global Health, whose Hemafuse autotransfusion system prices only $120. Even lower-cost choices could also be on the horizon, together with one being developed at Christian Medical College Vellore that’s housed inside a cardboard field and makes use of gravity to assist suction out blood from the affected person, says Raykar. The system wouldn’t require electrical energy to function and could be fully disposable.
Ultimately, the problem for autotransfusion will likely be guaranteeing entry to this new know-how and shifting surgical tradition towards its use. “The more you practice something, the more you see it works,” says Awadh. “Still more needs to be done for a surgeon to just decide, ‘Let me do this,’ without being prompted to think about it.”
A worldwide well being disaster that is ignored
For Raykar, the largest problem is getting folks to care about blood deserts. “These are the poorest, socioeconomically most vulnerable patients in the world. They die at high rates, and it’s attributed to poverty. But the actual reason why they died is often not recognized.”
While HIV activists have benefited from a long time of advocacy and sturdy funding, those that die in blood deserts — as a consequence of trauma, anemia or postpartum bleeding — command comparatively little consideration.
“All of these people are invisible, so they will never reach the policy table to say, ‘Hey, if I get the blood of someone with HIV today, I will die maybe ten years from now or never at all because treatment is so good,'” says Roy. “‘But if I don’t get blood today, I will be dead today.'”
To be clear, not one of the physicians and affected person advocates I interviewed thought that strolling blood banks, drone-based supply or autotransfusion may supplant the necessity for conventional blood banks. These methods are solely meant to be stopgap options.
Yet within the slow-moving political panorama of many low- and middle-income international locations, it is unclear if these measures will ever go from a list of recommendations to widespread implementation.
“Blood is not catchy; it’s not sexy. It’s not the kind of thing that the cameras are following you,” says Wangamati, the previous first girl. “So I talk about blood everywhere, to anyone who will listen.”
