When Caroline Wangamati was touring a rural Kenyan hospital in 2018, the medical doctors shared that two younger moms would seemingly be useless 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 woman of Bungoma County on the time, frantically referred to as the regional blood heart — 85 miles away — to have them ship some items.
The supply arrived a couple of hours later. “I used to be very happy with myself,” Wangamati tells NPR. “After the blood got here in and we transfused the ladies, I went to see the medical superintendent and was saying, ‘I’m so glad we bought them this blood as a result of these two ladies would have died.'”
“He advised me, ‘But Ma’am, you did not go to the pediatric ward. We had greater than 9 sufferers that wanted blood.'”
Across the world, lots of of hundreds of thousands, if not billions, of individuals stay in areas the place there’s not sufficient blood in no less than 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 extremely treatable situations — trauma, sickle cell anemia or postpartum bleeding — usually grow to be lethal. “Blood is a life-saving drug; it is thought of important drugs,” 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 usually 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 aim to do one thing, realizing full effectively you are not going to succeed with out blood transfusion,” he says. “And your second choice is to inform the affected person, ‘Nope, sorry, we won’t deal with you right here. But you possibly can go to the district hospital, which is 2 to 4 hours away,’ realizing full effectively they are not going to make it.”
Global well being companies have lengthy championed blood banks as the answer. But that assumes there’s cash to construct high-quality storage amenities and dependable sufficient electrical energy to take care of refrigeration, to not point out the logistical experience to recruit donors, display screen blood and distribute items on time. So whereas there are dozens of blood banks in large cities like New Delhi or Nairobi, there are basically none in rural Bihar or Turkana County, says Raykar. “We’ve waited many years for sufficient blood banks to be constructed, and we will be ready a number of many years extra.”
Raykar and his workforce recognized the three most revolutionary options for the world’s blood deserts within the Lancet Global Health. Whether there’s the political will to deal with this disaster, nevertheless, 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 — usually unlawful — workaround: “strolling blood banks,” the place medical doctors do not retailer blood in fridges however rely 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 illnesses on the spot, it’s instantly transfused to the affected person — no blood financial institution required.
In particularly dire circumstances, health-care employees typically roll up their very own sleeves. “This mom was dying, and her medical doctors gave three pints of their very own blood. And they watched the mom actually come again from demise,” recounts Wangamati, who can be considered one of Kenya’s 4 apponted “Blood Ambassadors,” elevating public consciousness across the concern. “This follow is completed in virtually each hospital within the nation; it is simply that they can not shout about it — as a result of it is unlawful,” she says.
Indeed, Kenya is considered one of many low- and middle-income international locations that banned strolling blood banks within the Nineties and 2000s — the results of HIV activists calling for zero tolerance for blood-transmitted circumstances and corresponding stress 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 consultants.
In India, for instance, the National AIDS Control Organization took over blood transfusion tasks from the Ministry of Health in 1996. Three years later, the federal government banned strolling 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 should report the metrics of what number of transfusion infections occurred per yr, not the quantity of people that died due to lack of blood — that is utterly ignored.” Dr. Shobini Rajan, chief medical officer of India’s National AIDS Control Organization, declined to remark.
“There’s a continuing rigidity between entry and security,” Raykar continues. At native clinics, speedy diagnostic checks may display screen strolling blood financial institution donations for HIV and different transmissible illnesses with 98-99% accuracy. But in its newest steering from April 2023, WHO strongly recommends in opposition to these checks and strolling blood banks — outdoors of an “acute emergency.” A WHO spokesperson defined in a press release to NPR: “While the transfusion of blood collected from donors to sufferers can save lives, it entails dangers itself and will trigger critical penalties, even demise of sufferers.” 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 “reasonably imprecise, reasonably open to interpretation” — with out acknowledgement that blood deserts themselves are in a state of emergency.
“Extreme blood shortage in a lot of the world is just not an impending, catastrophic occasion, however the present established order,” says Roy. But implementing 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 truth, 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 road to save lots of a life,” says Wangamati, who skilled in well being coverage on the London School of Economics. “Can we now have the boldness to take a look at strolling blood banks as an answer for these instances when blood is just not there?”
Yetmgeta Abdella, a transfusion drugs physician and the fast 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 isn’t so easy to show to strolling blood banks given accuracy points with speedy diagnostic checks. “In international locations in Africa and Asia, the environmental situations are so various and typically hostile, so if you do not have the best storage situations for the check equipment, you’ll not have the right end 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 essential 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. navy has adopted strolling blood banks as a protected, efficient transfusion technique in struggle zones. “What we stay by each day in these blood deserts is nothing wanting that,” Roy says. “How many individuals have to die earlier than you say that that is struggle?”
Blood supply by drone
Given the controversy round strolling blood banks and the extent of the scarcity, international well being consultants have explored different methods to additional broaden entry to blood.

Perhaps essentially 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 usually too gradual 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 4 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 by the skies at 75 miles per hour. “It’s just about like Amazon,” says Roy. “You cease making an attempt to have retail shops in all places; you simply have a giant hub and a extremely environment friendly supply system.”
While Raykar is happy about all methods to get blood to suppliers, he acknowledges that drone-based deliveries aren’t a magic bullet since they can not tackle an absence of provide. Already, WHO recommends a minimal of 10 items 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 firms are flying blood from locations designed for blood assortment, however in the end, we nonetheless want extra blood domestically,” Raykar says.
An answer throughout surgical procedure
Beyond drones, some international well being consultants have turned to autotransfusion, the place surgeons acquire blood pooling inside sufferers’ our bodies, use a tool to scrub it up after which return their blood.
“Instead of throwing it away and working round on the lookout for a alternative, we are able to simply simply choose that blood and provides it again,” 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 illnesses or verify for matching sorts. That saves time and cash. There’s an oblique profit as effectively: If medical doctors recycle blood of surgical sufferers, they will 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 ladies struggling miscarriages, filtered it by gauze and transfused it again. While generally used in the present day 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 value of most autotransfusion units, restricted coaching in these strategies 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 solely $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 utterly disposable.
Ultimately, the problem for autotransfusion will probably be guaranteeing entry to this new know-how and shifting surgical tradition towards its use. “The extra you follow one thing, the extra you see it really works,” says Awadh. “Still extra must be finished for a surgeon to simply determine, ‘Let me do that,’ with out being prompted to consider it.”
A worldwide well being disaster that is neglected
For Raykar, the largest problem is getting folks to care about blood deserts. “These are the poorest, socioeconomically most weak sufferers on this planet. They die at excessive charges, and it is attributed to poverty. But the precise cause why they died is commonly not acknowledged.”
While HIV activists have benefited from many years of advocacy and strong funding, those that die in blood deserts — as a result of trauma, anemia or postpartum bleeding — command comparatively little consideration.
“All of those individuals are invisible, so they may by no means attain the coverage desk to say, ‘Hey, if I get the blood of somebody with HIV in the present day, I’ll die possibly ten years from now or by no means in any respect as a result of therapy is so good,'” says Roy. “‘But if I do not get blood in the present day, I will probably be useless in the present day.'”
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 listing of suggestions to widespread implementation.
“Blood is just not catchy; it isn’t attractive. It’s not the sort of factor that the cameras are following you,” says Wangamati, the previous first woman. “So I discuss blood in all places, to anybody who will pay attention.”
