Mysterious elephant deaths in Kenya raise questions around pesticides

Bunia, Democratic Republic of the Congo – As Ebola cases continue to emerge in the eastern Democratic Republic of the Congo (DRC), Virunga National Park – Africa’s oldest – is strengthening health measures to protect communities and the endangered mountain gorillas living in it.The measures are part of the park’s emergency response after the World Health Organization (WHO) declared the Ebola outbreak in the DRC and neighbouring Uganda a Public Health Emergency of International Concern in May.“It is a terrible disease and one that poses a threat first and foremost to human populations. Protected areas such as Virunga National Park are vast natural spaces where there are no human populations. They act as barriers to the spread of the disease,” Emmanuel de Merode, director-general of Virunga National Park, told Al Jazeera.Virunga previously supported efforts to contain the DRC’s 10th Ebola outbreak between 2018 and 2020, which killed nearly 2,300 people in North Kivu and Ituri provinces. De Merode believes the park can again contribute to slowing transmission during the country’s 17th outbreak, which has killed more than 1,400 people, according to Congolese health authorities.Rangers and health workers join the responseThe park has established six health checkpoints within and around its territory, a 300km (186-mile) stretch of protected forest that park officials describe as a natural barrier across North Kivu. It has also deployed 40 paramedics alongside 80 rangers as part of an initial six-month emergency response.De Merode told Al Jazeera the checkpoints on roads crossing the park allow authorities to monitor movement through the protected area.Mountain gorillas in Virunga National Park [Courtesy of Virunga National Park]“We are setting up checkpoints, which act as roadblocks, together with health units for handwashing and temperature screening, and a first-level isolation centre next to each checkpoint,” he said.In Ituri province, the epicentre of the outbreak, checkpoints north and south of Bunia, the provincial capital, are screening travellers arriving from areas affected by Ebola.“We have supported the health service with protective equipment, body bags, thermometers and vehicles because, when the disease first broke out, the health services faced real difficulties, particularly in North Kivu,” de Merode said.Virunga, a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site since 1980, is located in a region that has experienced more than two decades of armed conflict. More than 800 rangers protect the park, which is home to a number of the world’s most threatened species.A wider role in the Ebola responseDe Merode said experience from previous outbreaks has strengthened cooperation between Virunga and Congolese health authorities, particularly in surveillance and early detection.Reflecting on the 2018-2020 Ebola response, he said members of the outbreak response committee considered Virunga an important factor in limiting the spread of the virus.“The response committee at the time noted that the fact the disease never widely spread to Goma or to other parts of the country was also due to Virunga National Park, which was considered a major factor in preventing the disease from spreading southwards or eastwards,” he said.De Merode stressed that Virunga remains only one part of a wider response led by Congolese health authorities and supported by technical and financial partners.“All the information collected at our checkpoints is immediately transmitted to the Congolese National Institute of Public Health for follow-up,” he said.In Ituri province, three checkpoints managed by the Congolese Institute for Nature Conservation within Virunga are screening travellers arriving from areas most exposed to Ebola.Park officials say two suspected cases have been identified at the checkpoints and referred to public health authorities for monitoring.“If, unfortunately, cases do arise beyond the c
