When Caroline Wangamati was touring a rural Kenyan hospital in 2018, the medical doctors shared that two younger moms would possible be lifeless inside hours.
Their hemoglobin ranges had been catastrophically low — an indication of life-threatening anemia. The everyday response can be a blood transfusion, however the native blood financial institution was empty.
So Wangamati, the primary woman of Bungoma County on the time, frantically known as the regional blood middle — 85 miles away — to have them ship some models.
The supply arrived a couple of hours later. “I used to be very pleased 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 am so glad we bought them this blood as a result of these two ladies would have died.'”
“He informed me, ‘However Ma’am, you did not go to the pediatric ward. We had greater than 9 sufferers that wanted blood.'”
The world over, lots of of hundreds of thousands, if not billions, of individuals dwell in areas the place there’s not sufficient blood in at the least 75% of medical instances. Final month, a coalition of 27 medical doctors, researchers, and affected person advocates coined the time period “blood desert” in a Lancet International Well being paper final month, hoping to construct consciousness and share options.
In a blood desert, what are usually extremely treatable circumstances — trauma, sickle cell anemia or postpartum bleeding — usually turn out 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. However practically each nation in sub-Saharan Africa and South Asia is battling deficits, in response to a 2019 Lancet Haematology examine.
Given such shortages, physicians usually have solely two selections when their sufferers endure main bleeding, in response to Dr. Nakul Raykar, a trauma surgeon at Brigham and Ladies’s Hospital. “One is to try 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. However you may go to the district hospital, which is 2 to 4 hours away,’ realizing full effectively they are not going to make it.”
International well being companies have lengthy championed blood banks as the answer. However that assumes there’s cash to construct high-quality storage amenities 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 large cities like New Delhi or Nairobi, there are primarily none in rural Bihar or Turkana County, says Raykar. “We have waited many years for sufficient blood banks to be constructed, and we’ll be ready a number of many years extra.”
Raykar and his workforce recognized the three most modern options for the world’s blood deserts within the Lancet International Well being. Whether or not there’s the political will to handle this disaster, nevertheless, stays unsure, given the rigidity of HIV-era laws and the invisibility of sufferers in danger.
Strolling Blood Banks and HIV Controversy
There is 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.
Well being-care staff determine these individuals 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 straight transfused to the affected person — no blood financial institution required.
In particularly dire circumstances, health-care staff generally roll up their very own sleeves. “This mom was dying, and her medical doctors gave three pints of their very own blood. And so they watched the mom actually come again from loss of life,” recounts Wangamati, who can also be one in every of Kenya’s 4 apponted “Blood Ambassadors,” elevating public consciousness across the challenge. “This apply is finished in nearly each hospital within the nation; it is simply that they cannot shout about it — as a result of it is unlawful,” she says.
Certainly, Kenya is one in every 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 instances and corresponding stress from the World Well being Group and the U.S. President’s Emergency Plan for AIDS Reduction, in response to Raykar and a number of other different world well being consultants.
In India, for instance, the Nationwide AIDS Management Group took over blood transfusion tasks from the Ministry of Well being in 1996. Three years later, the federal government banned strolling blood banks within the title of security.
“Their sole mission is zero transmission of HIV,” says Raykar concerning the Nationwide AIDS Management Group. “They need to report the metrics of what number of transfusion infections occurred per 12 months, 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 Nationwide AIDS Management Group, declined to remark.
“There is a fixed stress between entry and security,” Raykar continues. At native clinics, fast diagnostic checks might display screen strolling blood financial institution donations for HIV and different transmissible illnesses with 98-99% accuracy. However 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: “Whereas the transfusion of blood collected from donors to sufferers can save lives, it includes dangers itself and will trigger severe penalties, even loss of life 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 “relatively imprecise, relatively open to interpretation” — with out acknowledgement that blood deserts themselves are in a state of emergency.
“Excessive blood shortage in a lot of the world just isn’t an impending, catastrophic occasion, however the present established order,” says Roy. However imposing federal legal guidelines, police will punish medical doctors for turning to strolling blood banks in emergency conditions, when sufferers could also be getting ready to loss of life.
In reality, 4 physicians interviewed for this story described how fellow health-care staff have been arrested for utilizing strolling blood banks. “They put their jobs on the road to avoid wasting a life,” says Wangamati, who educated in well being coverage on the London Faculty of Economics. “Can now we have the boldness to take a look at strolling blood banks as an answer for these instances when blood just isn’t there?”
Yetmgeta Abdella, a transfusion drugs physician and the instant previous medical officer for blood on the WHO Regional Workplace for the Japanese 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 fast diagnostic checks. “In international locations in Africa and Asia, the environmental circumstances are so numerous and generally hostile, so if you do not have the correct storage circumstances for the check package, you’ll not have the proper 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 examine he revealed within the Journal of Laboratory Physicians, the place throughout ten fast 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 necessary and that extra analysis is required to validate efficiency in blood deserts. Nonetheless, 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 battle zones. “What we dwell via daily in these blood deserts is nothing in need of that,” Roy says. “How many individuals have to die earlier than you say that that is battle?”
Blood supply by drone
Given the controversy round strolling blood banks and the extent of the scarcity, world well being consultants have explored different methods to additional develop entry to blood.

Maybe probably the most flashy innovation has been drone-based supply: flying blood to hard-to-access rural areas. Ambulances might 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 response to Raykar.
On 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 is just about like Amazon,” says Roy. “You cease attempting to have retail shops in all places; you simply have a giant hub and a extremely environment friendly supply system.”
Whereas 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 tackle 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. After which there’s the possibly prohibitive start-up investments for any drone-based supply program — over $4 million within the Rwanda instance.
“These corporations 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
Past drones, some world well being consultants have turned to autotransfusion, the place surgeons accumulate blood pooling inside sufferers’ our bodies, use a tool to scrub it up after which return their blood.
“As a substitute of throwing it away and working round in search of 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 examine 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 circumstances requiring transfusions.
The concept behind autotransfusion is not new, with the primary documented case in 1914. A German physician took blood from ladies struggling miscarriages, filtered it via gauze and transfused it again. Whereas generally used in the present day within the U.S. with the $20,000 Cell Saver gadget, autotransfusion hasn’t taken off in low- and middle-income international locations, Awadh says, due to the excessive value of most autotransfusion gadgets, restricted coaching in these strategies and considerations over sufferers’ blood being contaminated throughout an operation.
However there are methods to get across the value barrier. Awadh works as a coach for the medical gear firm Sisu International Well being, whose Hemafuse autotransfusion gadget prices solely $120. Even lower-cost choices could also be on the horizon, together with one being developed at Christian Medical Faculty 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 gadget wouldn’t require electrical energy to function and can be utterly disposable.
Finally, the problem for autotransfusion shall be making certain entry to this new expertise and shifting surgical tradition towards its use. “The extra you apply one thing, the extra you see it really works,” says Awadh. “Nonetheless extra must be carried out for a surgeon to only resolve, ‘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 individuals to care about blood deserts. “These are the poorest, socioeconomically most weak sufferers on the earth. They die at excessive charges, and it is attributed to poverty. However the precise cause why they died is usually not acknowledged.”
Whereas HIV activists have benefited from many years of advocacy and strong funding, those that die in blood deserts — on account of trauma, anemia or postpartum bleeding — command comparatively little consideration.
“All of those persons are invisible, so they’ll 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 remedy is so good,'” says Roy. “‘But when I do not get blood in the present day, I shall be lifeless 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 might supplant the necessity for conventional blood banks. These methods are solely meant to be stopgap options.
But within the slow-moving political panorama of many low- and middle-income international locations, it is unclear if these measures will ever go from an inventory of suggestions to widespread implementation.
“Blood just isn’t catchy; it is not horny. It is not the type 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 hear.”
