Trouble in paradise
Kush Patel reports on the violence that occurred in Kenya following the elections earlier this year.
For many years, Kenya has been considered as a refuge for people fleeing their own country because of domestic turmoil. However, on 29th December 2007, shouts emanated from an angry throng that had gathered on the streets. Marching determinedly towards them was a battalion of riot police. Within seconds, the rioters hurled stones at the police, who counterattacked using bullets and tear gas. In other parts of the country, youths clutching machetes and sticks launched themselves upon opposing tribes. Events such as these set the scene for a blood bath that has resulted in thousands of people injured, dead or homeless. Several camps for internally displaced people (IDP) were set up all over the country. Governmental and non-governmental organisations (NGOs) such as Merlin, Medecins sans frontiers (MSF), the Red Cross, AMREF and others, deployed teams to provide humanitarian aid.

Trauma victims requiring medical attention overwhelmed the medical facilities. When particularly violent clashes broke out, trucks full of injured or dead people arrived at hospitals, which in-turn became so over-crowded that patients were being treated on the corridors. A system of triage was implemented at many institutions, thus helping to treat the most severe patients first. (2,3) Patients were being rushed in with broken bones, stab injuries, blunt trauma and burns. Doctors reported certain cases where patients had sustained machete wounds that resulted in near-amputations. (3) Flying surgical teams were put on high alert, responding to violence in inaccessible regions. (4) In the worst hit areas, temporary first-aid posts were setup that quickly stabilized victims, while waiting for transport to hospitals. Any person who was critical and needed specialist care was air-lifted to the closest hospital. (3) Many of the victims were (and some still are) mentally traumatized from witnessing the violence or having lost loved ones. These people were given psychosocial support by medical personnel. (2,3)
Cases of sexual violence increased dramatically. These incidents took place both within IDP camps and outside. This will probably result in increased incidence rates of sexually-transmitted diseases, including HIV infection. Counselling and screening for sexually-transmitted infections have commenced in certain areas. (4)
Many people have been displaced and gathered at temporary IDP camps. At these camps severe public health consequences can manifest amongst the IDPs.. Four main reasons behind this are that the population is displaced, food becomes scarce, health care diminishes and living conditions worsen. Studies have shown that mortality rates are usually highest immediately after the migration. (1) Apart from the acute emergencies, an increasingly large number of IDPs need to be accommodated. At each IDP camp, tents were pitched, food and water was provided, sanitation and lavatory facilities were set up and medical camps were established. (2-6) Other essential equipment such as bed nets, (6) cooking apparatus, (3) and clothing, (2,4) was provided to the IDPs. Most IDPs had left their homes without anything. For many, important documentation was lost. Therefore, the task of registering the IDPs and getting new identification cards for them was set into motion. In order to keep the IDPs busy and lessen their emotional stress, some were given responsibilities in the camps such as cleaning. (2) Some NGOs have setup tracing agencies that help reunite lost family members.(4) Planes and helicopters had to be employed to deliver medical and other essential supplies to ill-equipped areas.(3)
The most prevalent diseases amongst IDPs are diarrheal diseases, measles, acute respiratory infections, and malaria. Additionally, many people became malnourished because of the lack of food. This aggravates diseased states and worsens the patient’s prognosis.(1) At a single camp, 541 consultations were done mainly for respiratory tract infections.(3) Most of these patients were children and many had a poor prognosis. Factors that contribute to a high prevalence of respiratory tract infections are: over-crowding, poor ventilation, inadequate shelter, and prolonged exposure.(1)
The measles immunization was provided for children.(3) For those who survive the initial illness, it can lead to malnutrition and vitamin A deficiency. Previously, measles has accounted for high mortality rates amongst children in refugee camps. However, it is less of a threat now compared to before 1990.(1)
Diarrhoeal diseases are a common phenomenon in IDP camps. Factors that contribute to their high prevalence are unsanitary conditions and unsafe drinking water. Cholera and dysentery are the main problems. In some IDP camps, diarrhoeal epidemics had broken out. These were usually treated with oral rehydration salts. However, any serious cases of diarrhoea were referred to a hospital.(4)
Kenya has a high prevalence of tuberculosis (TB) (7) and AIDS. (8) A lot of IDPs with TB or AIDS fled their homes without anything, including their anti-tuberculosis or antiretroviral drugs.(2,3,6) Adding to this, the number of patients attending HIV/AIDS clinics reduced dramatically.(3) This can have serious consequences on their health, as non-compliance results in the development of drug-resistance. Patients also become susceptible to opportunistic infections and their risk of morbidity and mortality increases.(8) One report mentioned a woman trapped at home, unable to gain access to a new dose of anti-retrovirals. As a result, when she was found by relief workers, an infection had set in and she had to be admitted to hospital.(9) Another hurdle with respect to anti-retrovirals is that many HIV patients were not getting adequate nutrition. This resulted in patients unable to tolerate their medication, further increasing non-compliance.(9) Patients with tuberculosis, face a similar scenario where drug-resistance develops.(4,7) The problem with this is that patients then require second-line drugs that are more expensive than first-line drugs.(4) Long-term effects of this may result in increased infection rates within the population. These 2 diseases were a major concern for the NGOs, who constantly held testing clinics, offered counselling and provided medication.(6,2,3) Thankfully this volatile situation has calmed down allowing people to piece together their lives. Medical attention has also improved in most areas. (6)
A correspondent from Merlin gave the following account of a typical day at an IDP camp:
The day usually starts off early, with a meeting discussing the day’s agenda. A clinic is setup wherever space is available (a vacant room or under a tree). Patients are then prioritized according to their level of urgency. Immunizations, HIV testing and counselling and treatment for minor illnesses are provided to those who need them. For those who require referrals to health centres or hospitals, transportation is arranged. Other team members conduct health education sessions for patients while they wait for their consultation.
