The young mother was not doing well.
Living in a remote village in the Jinja region of Uganda, she
had given birth to a baby just a few weeks before, but she was feeling weakness
on her right side of her body and had fevers. She was under the care of a traditional healer (sometimes referred to as “Shamans” or “Witch Doctors”) who had
instilled cuts on her body as part of the treatment, making her condition worse. Dr. Schiff and his team examined her and thought she most likely had a stroke as well as an infection. He immediately
arranged for an ambulance to come to the remote village and get her. Empty space in the ambulance was filled with 4
other babies from the village who were also in need of medical attention – 3 had
fevers, one had a discharge around the umbilical cord which wasn’t cut close to
the body, one had pustules on the skin, and one had very yellow eyes, meaning
it had jaundice early in life, a condition that can lead to brain damage if it isn’t
treated.
Once they arrived at the hospital, the young mother was scheduled
for a CAT scan, plus treatment for an infection and high blood pressure. But then the traditional healer called the
hospital, demanding that the young mother return home. When we last heard, the young mother was
getting ready to leave the hospital early to comply with the healer’s demands.
Trying to Identify the Source
This was the 4th remote village that Dr. Schiff and his medical team had visited, as part of a multi-disciplinary effort to find out why there have been so many newborn infections, which if infants survive long enough can lead to Hydrocephalus (water on the brain) requiring surgery. In addition, a preventable serious malformation of the spine called Spina Bifida seems to be occurring at very high rates in the area. After 20 years of research, Dr. Schiff had identified a bacterium called Paenibacillus thiaminolyticus as being the root cause of some of the most deadly of the newborn infections, and the one that most often led to hydrocephalus. Now the race is on to figure out how the bacterium is transferring to the newborns. Is it in the water? The soil? Through the mother? Traditional after-birth practices that have been used for thousands of years, and still persist despite the heightened risk of infections?
Dr. Carmit Cohen, a veterinarian and a microbiologist, joined the team on this trip. |
To find out, a multi-pronged master plan was devised:
1) An army of Village Health Team (VHT) workers has been assembled to go out to the remote villages and canvas the health of the babies, filling out questionnaires on their cell phones and electronically sending the results to a central database.
2) On-site sampling of the environment including soil, water, and animal feces.
3) Creation of a Geographical Information System to understand correlations between measurable ground conditions and increases in the infection rates.

What Took so Long?
These plans were being talked about 10 months ago, when Part
1 of this article was written. The
strategy is certainly straightforward.
Why did it take so long to actually start executing?
“I think it went rather smoothly”, Dr. Schiff responds. “We had to assemble a team of laboratory technicians and set up the lab. We had to assemble an army of about 750 volunteers to form the Village Health Team, we had to create the electronic questionnaire, the database and the dashboard to help us visualize all of the data in real time. Then we had to get permission to do all of the field work.”
Everything is being measured. |
It turns out that getting the permission took the greatest
amount of time, starting with the
Ugandan ethics committee. "They very
carefully went through all of our proposals, asked us questions, we would
respond, and revised our proposals, and finalize the proposals and
consents. The consents are also
translated into local languages. In the
end, there were, I think, 31 documents that had to be approved.”
“Once that’s done it goes to the Ugandan government
oversight agency, the Ugandan National Council on Science and Technology
(they’re responsible for all of the ethics committees). It takes them awhile to review things. Then when they approve, it all goes to the
United States’ Institutional Review Board.
They have more questions. They
want other changes to be made. So we
went back and forth a few times with our ethics committee, and in the end we
have to unify the protocols. Separate consent was also needed for the electronic questionnaire and consent to sample from the homes and village that we developed.”
Who knew? 😊

The Field Work Begins
After the interview, the mother is thanked with a care package consisting of diapers, crackers, sugar, and rice. |
“When was the baby born?”, asked the Village Health Team
volunteer. “Was he or she healthy? Does/Did the baby have any of these
symptoms?”, and then a whole laundry list of possible problems were listed: fever,
fast breathing, not feeding, convulsions, redness around the umbilical stump…
Now that the surveillance was fully approved, this was the first opportunity Dr. Schiff had to actually witness the VHTs in the field conducting the study and examine the conditions the babies were living in. In doing so, some problems with the way the questions were written began to surface. Some of the names of common medications were unknown to both the mother and the VHT member. And the experience of the young mother who had a stroke prompted changes to the survey, to ask whether the postpartum mothers are ill, or to report whether a mother has died following childbirth. The purpose of this survey is to just gather data; there is no budget for actually arranging for medical transport or to pay for health services. The team intends to layer onto this surveillance system strategies to substantially reduce the preventable causes of neonatal and infant mortality that they are focusing on: infections and congenital malformations such as the open spines of Spina Bifida.
While the questionnaire is mainly designed to track the
health of newborns, it is always a secondary goal to use the VHT’s presence as
an ambassador for hospital care and for western medicine. But just the idea of taking a pill every day can be a foreign concept that isn’t always adhered to if prescribed, and the rural people don’t have access to supermarkets or pharmacies. Folic acid, for example, has been proven to prevent
many serious malformations during pregnancy. VHTs recommend it, but the data so far shows
that it’s not being taken. What
compounds this difficulty is that the rural people do not purchase food in
commercial markets where grains fortified with folic acid might be present. “In Uganda, folic acid is also a kind of
double-edged sword” says Dr. Schiff, who points out that while it’s effective
in reducing neural tube defects and birth defects of the brain and spinal cord,
it can also make amplify the deadly effects of malaria.
The walls are made of a mixture of mud and cow dung. Could this be a source of some of the infections? |
During my visit, four villages were visited to perform
sampling of the soil, water, animal feces, and to look for any other possible
source of infection, such as the walls of the dwellings which are made up of a combination
of mud and cow dung. The team was joined by Dr. Carmit Cohen, a
veterinarian from Israel who’s also a molecular biologist. (“Because what do us surgeons know about
cows?” Dr. Schiff jokes.)
The villages are all completely off the grid and self-sufficient in terms of growing food and livestock. Everyone wore western-style clothing and most had access to a cell phone; solar panels on the roofs provided a means of charging. The children roamed carefree and seemed happy. It was quite picturesque.
Cultural Barriers
Looking for correlations in mountains of data at the Jinja Regional Referral Hospital. The left side is a map where all 60,000 villages in Uganda were fused with the satellite climate map grid, and mapped onto it were the locations of 20 years' worth of postinfectious hydrocephalus cases. The right graph suggests an increase in hydrocephalus when the rains come two weeks before birth. |
Henry Masengere and Dr. Ericson prepare the samples for lab testing. |
In addition to the environment, there are many traditions,
some of them thousands of years old, that are making the problem worse. One is the practice of placing foreign
materials (sometimes including cow dung) on the open umbilical cord. One is the use of a traditional birthing
attendant, which was outlawed in 2010 due to high maternal and child mortality
rates, which were attributed to poor hygiene, unhygienic conditions, and a lack
of training. (They are sometimes still
being used despite the ban.) Then of
course there are the traditional healers which often make matters worse. Add to that the lack of access to supplements to prevent malformations, and medications to treat infections, and this kind of mission becomes a real uphill battle.
The traditional healer incident described at the beginning
of this story has already catalyzed some progress. After some tense phone calls, they now have
an agreement in place with the traditional healers to meet and discuss working together and avoid
incidents like this in the future.

Ward 7 of the Jinja Regional Referral Hospital |
Drs. Schiff and Ericson examine a premature baby with a growth at the base of her spine. After birth she had a little difficulty breathing which is typical of premature babies because their lungs are underdeveloped. She was born on an island on one of the lakes so they took a boat to the mainland and then went to a lower-level health center. They were then referred to a regional hospital so they then took a motorcycle taxi to the regional hospital. She’s now getting oxygen for her respiratory needs. The rather large 2-inch “squishy mass” at the base of her back prompted concerns about either a type of spine defect or perhaps a type of tumor that can be hard to distinguish from a spine defect without special imaging. So once her respiratory illness is improved, she’ll be sent to one of the hospitals that has a CT scan and a neurosurgeon to have either the defect repaired, or an associated tumor removed. |

Dr. Cohen, an Israeli, has been around the world but this was the first country to be excited about her visitation. Christianity has a strong presence here, and people got excited because Israel is the place where all of the biblical stories they've been reading about takes place. "I'm in recovery; can you bless my journey?" |
Dr. Cohen obliged. |
Epilogue
Dr. Schiff's work continues, both in Africa and Vietnam, despite some funding challenges from the NIH. Some of that shortfall is made up by some very gracious private donors.
As of this writing, the lab samples are in frozen storage, waiting for transport to Yale to be arranged. It might be months before the tests results are known.
Tests from last year have ruled out the infections happening through the mother.
Environmental infections should be preventable, and Dr. Schiff wants to craft policy to address the sources and routes of infection that they identify. The Dashboard lets the team, and the Ugandan and Kingdom collaborators, see right away if policies are reducing the number of newborns that fall ill or not. Schiff is hoping to start the first infection prevention trials soon. Preventing the malformations will require additional studies which he hopes to begin organizing soon.
In the end, the goal is to have a major impact on these preventable causes of infant mortality in regions of sub-Saharan Africa such as this where infant mortality rates are far too high.
