On est entre la saison des papayes et celle des mangues (en plus de celle des serpents, des scorpions et des pluies). Le mois dernier, le papayer sur le terrain de la base nous a donné quelques beaux fruits. Le hic, c’est d’aller les chercher. Les papayes, sans doute de 1 à 2 kg, sont perchées à environ 10 m du sol, confortablement haut dans leur arbre. Il faut prendre une longue tige de bambou et les décrocher, au risque de se taper une bonne commotion cérébrale. Notre gentil log-forage anglais s’était mis à la tâche pour nous dénicher du dessert. Après deux papayes un peu vertes qu’il a agilement attrapées manière rugby, une papaye bien mûre lui a éclaté dans les mains, le couvrant de jus visqueux et odorant. Nous n’avons pas pu retenir les esclaffades de rire. Quel sacrifice quand même! Disons que la salade de papaye verte a été excellente ce jour-là.
Maintenant ce sont les mangues qui jouent à Sir Isaac Newton. Dans nos pérégrinations en Land Cruiser, j’admire les lourdes branches de manguiers qui se penchent au-dessus de la route. Les chauffeurs les évitent avec soin. A ma perplexité, on m’a répondu qu’une mangue verte qui tombe est un dangereux projectile auquel les pare-brise ne résistent pas. Il faut donc faire attention, car remplacer un pare-brise nous coûterait de précieux délais en visites de village.

En termes d’autres fruits, on vient de découvrir que les grands arbres à l’entrée de la base sont des goyaviers. Tous les jours, des enfants y sont grimpés et se pourlèchent les doigts; pourtant, pas l’ombre d’une goyave au grand marché du centre-ville shamwanais. Il semblerait obligatoire de défier les lois de la gravité pour profiter des goyaves roses et parfumées. Avec un peu de chance, j’arriverais peut-être à fabriquer un bon petit sorbet de goyave, comme je les aime tant l’été à Montréal sur le Plateau... Il faut bien pouvoir rêver un peu ;)

Traversées horizontales
Every week brings new challenges. The approaching wet season is acquainting us with another old disease. Just like tuberculosis, cholera has been living with humankind for a long time. But unlike tuberculosis, it does not have a protracted course of chronicity. Rather, it uses the method of killing by numbers to spread fast. The cholera bacterium, Vibrio cholerae, is found in bodies of stillwater. In small quantities, it produces a nondescript gastroenteritis. But if the bacteria are ingested in large amounts, cholera kills very rapidly by producing a toxin that adheres to the intestinal wall and makes a human lose all its water from both ends. People die of dehydration and hypovolemic shock within a matter of a few hours: it’s typically a ‘rice-water diarrhea’. The incubation period can be anywhere from a few hours to five days, and the human secretions produced are highly infectious. Hence the potential for epidemics. The bacteria is known to have originated from the Indian subcontinent, where there is enough human density to sustain ongoing epidemics and mutations. The last world pandemic started in Bengal in 1991 and was carried all the way to Latin America. I vaguely remember the story of people dying after eating oysters on a South American airline crossing the continent. In Africa, where the water supply is generally unsafe, cholera epidemics are chronic.
In our region, the cholera usually comes from lake Mwero where Kilwa sits, a few hundred kilometers away. The way to deal with cholera is simple: the patient must be given back all the water that he is losing. If treated in time, recovery is close to 100%. But the disease moves fast. As soon as there is a case of cholera, we must set up cholera treatment centres. CTCs consist of a building with individual rooms, each with a cholera bed. The principle of the cholera bed is that it has a hole in the middle to gather the secretions that fall into a bucket right underneath. Patients are so sick that they cannot make it to the latrine. It is not unusual to give over 10 liters of intravenous fluid per day to a cholera patient. And the watsan (water-sanitation) people play a large role in the management of a cholera outbreak: large amounts of chlorine are used to disinfect the secretions, corpses if any, and to ensure isolation. The MSF protocol is complex and involves three concentrations of chlorine with specific uses.
Last week, our outreach team was flagged down from the road and brought a cholera patient to the health centre in Kishale, where we had set up a cholera treatment centre after a single case earlier in the year. However, more patients appeared this week. I was dispatched with the outreach team to investigate the new cases and report whether an epidemic was starting. The objectives were to contain the outbreak, verify the functioning of the cholera treatment centre, and to trace the contacts or contamination.
Arrived in Kishale, we looked at the cholera treatment centre and followed up on the patients. Both were now doing well. The centre consisted of a simple tent with dividers and cholera beds inside; our cholera beds are simply metal foldable bedframes and plastic tarp with the hole right over the bucket underneath. Basins with chlorinated solution were placed at all entrances of the tent, for shoe soaks. The nurse was reasonably well trained. Then, we investigated the movements and possible contacts of both patients, and visited their originating villages, as well as the road that they travelled. Quite the Sherlock Holmes enquiry, to research a cholera outbreak. We looked at the water sources, the river and the traditional wells used by the villages. It was quite interesting, as people move quite a bit, and it is virtually impossible to trace all contacts.
After much questioning and discussing with the chefs de village, the family members of the patients, and the Croix-Rouges, the local health workers, the puzzle solution slowly emerged. The index case had brought the cholera from lake Mwero at the village of Pweto, where he had gone to sell palm oil last week. He had had diarrhea the whole way back on the road to Kishale. Case number two probably travelled the same road around the same time and must have come in contact with his secretions. He died on the way to the health centre a few days later. Case number three crossed the same village as case number two on the same day, on her way to get some salt in another village. She then became sick on her way back home two days after. Case number four is a household contact of case number four. Crisscrossing paths in time and place, village after village, along roads and rivers – and cholera spreads. For the time being, we do not think that the water sources have been contaminated. But since the traditional wells are unprotected shallow spring water holes in the middle of the bush, it would be easy. Then we would have to teach all families to do bucket chlorination, which is a logistical watsan nightmare in our context. Let’s just hope that it doesn’t have to go that way. So for now, we remain on cholera watch.

Little girl with mortar, pestle and manioc. Girls start working at a very young age. When I took this picture and filmed her earlier today, boys her age who were running around gathered around me and wanted to look at the footage. They were all laughing, at which point I reminded them that she was working and they weren’t. They sheepishly answered: “Ah, c’est vrai...”
