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 standard 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 known as the regional blood middle — 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 am so glad we acquired them this blood as a result of these two girls would have died.'”
“He instructed 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 thousands and thousands, if not billions, of individuals reside in areas the place there’s not sufficient blood in at the very 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 World 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 — typically grow to be lethal. “Blood is a life-saving drug; it is thought of important medication,” says Dr. Nobhojit Roy, a retired rural surgeon from India. However practically each nation in sub-Saharan Africa and South Asia is fighting deficits, in accordance with a 2019 Lancet Haematology research.
Given such shortages, physicians typically have solely two decisions when their sufferers endure main bleeding, in accordance with Dr. Nakul Raykar, a trauma surgeon at Brigham and Ladies’s Hospital. “One is to aim to do one thing, figuring out full properly you are not going to succeed with out blood transfusion,” he says. “And your second possibility is to inform the affected person, ‘Nope, sorry, we will not deal with you right here. However you may go to the district hospital, which is 2 to 4 hours away,’ figuring out full properly they are not going to make it.”
World 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 blood and distribute items 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 crew recognized the three most modern options for the world’s blood deserts within the Lancet World Well being. Whether or not there’s the political will to deal with 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 — typically unlawful — workaround: “strolling blood banks,” the place medical doctors do not retailer blood in fridges however depend on drawing blood from neighborhood members.
Well being-care staff determine these individuals and, throughout occasions 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 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 demise,” recounts Wangamati, who can be considered one of Kenya’s 4 apponted “Blood Ambassadors,” elevating public consciousness across the difficulty. “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 considered one of many low- and middle-income nations that banned strolling blood banks within the Nineteen Nineties and 2000s — the results of HIV activists calling for zero tolerance for blood-transmitted instances and corresponding strain from the World Well being Group and the U.S. President’s Emergency Plan for AIDS Aid, in accordance with Raykar and a number of other different international well being consultants.
In India, for instance, the Nationwide AIDS Management Group took over blood transfusion obligations from the Ministry of Well being 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 concerning the Nationwide AIDS Management Group. “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 Nationwide AIDS Management Group, declined to remark.
“There is a fixed pressure between entry and security,” Raykar continues. At native clinics, speedy diagnostic checks might display 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 towards 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 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 “somewhat imprecise, somewhat 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 will not be an impending, catastrophic occasion, however the present established order,” says Roy. However 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.
The truth is, 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 save lots of a life,” says Wangamati, who skilled in well being coverage on the London Faculty of Economics. “Can we have now the boldness to take a look at strolling blood banks as an answer for these occasions when blood will not be there?”
Yetmgeta Abdella, a transfusion medication physician and the speedy 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 speedy diagnostic checks. “In nations in Africa and Asia, the environmental circumstances are so numerous and generally hostile, so if you do not have the best storage circumstances for the take a look at package, you’ll not have the right end result,” says Abdella.
Then comes the problem 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. Nevertheless, 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 reside via day by day 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, international well being consultants have explored different methods to additional broaden 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 typically too sluggish in emergency conditions, struggling to navigate poor roads and tough 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 accordance with 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 making an attempt to have retail shops all over the place; you simply have an enormous 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’t deal with a scarcity of provide. Already, WHO recommends a minimal of 10 items of blood donated for each 1,000 neighborhood members, however low-income nations do not even attain half that quantity. After which there’s the doubtless 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 finally, we nonetheless want extra blood regionally,” Raykar says.
An answer throughout surgical procedure
Past drones, some international well being consultants have turned to autotransfusion, the place surgeons gather blood pooling inside sufferers’ our bodies, use a tool to wash it up after which return their blood.
“As an alternative of throwing it away and operating round searching for a substitute, 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 for transmissible illnesses or verify for matching sorts. That saves time and cash. There’s an oblique profit as properly: If medical doctors recycle blood of surgical sufferers, they’ll 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 girls struggling miscarriages, filtered it via gauze and transfused it again. Whereas generally used right this moment within the U.S. with the $20,000 Cell Saver machine, autotransfusion hasn’t taken off in low- and middle-income nations, Awadh says, due to the excessive value of most autotransfusion gadgets, restricted coaching in these methods 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 tools firm Sisu World Well being, whose Hemafuse autotransfusion machine 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 machine wouldn’t require electrical energy to function and could be utterly disposable.
In the end, the problem for autotransfusion can be guaranteeing 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 achieved for a surgeon to simply resolve, ‘Let me do that,’ with out being prompted to consider it.”
A world well being disaster that is neglected
For Raykar, the most important 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 motive why they died is usually not acknowledged.”
Whereas HIV activists have benefited from many years of advocacy and sturdy 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 right this moment, 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 right this moment, I can be useless right this moment.'”
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 nations, it is unclear if these measures will ever go from a listing of suggestions to widespread implementation.
“Blood will not be catchy; it is not horny. It isn’t the form of factor that the cameras are following you,” says Wangamati, the previous first girl. “So I speak about blood all over the place, to anybody who will hear.”
