Ebola Outbreak-The deadly Epidemic

 The Ebola outbreak in DRC is not getting the required traction from the world despite being categorized as the fastest growing infection so far recorded by the World Health Organization (WHO). Before diving deep into the threats posed by this disease, it is imperative to provide the readers with an overview of this viral infection.

An Overview of Ebola Outbreak

The Bundibugyo virus, one of the Orthoebolavirus species is responsible for causing severe Ebola disease known as Bundibugyo virus disease (BVD). It is a zoonotic disease, with fruit bats suspected to be the natural reservoir.  With the close contact of a human to the blood or secretions of infected wildlife (including bats or non-human primates), the human gets the infection. Consequently, the infection spreads from one human to other through direct contact with the blood, bodily secretions, and organs of the infected ones. The viral infection can also spread through close contact with the surfaces and materials contaminated with the bodily secretions of the infected individuals. Very similar to the Corona virus, the spread of this infection is particularly high in health-care settings having inadequate sterilization measures in place. Moreover, a direct contact with the infected deceased individuals during their burial can contribute to its spread as well.

Incubation period and Clinical symptoms

The incubation period for BVD ranges from 2 to 21 days, and infected individuals are not infectious until symptom onset. Fever, fatigue, muscle pain, headache, and sore throat may represent as the early symptoms of this disease. But the non-specific nature of these symptoms often makes the diagnosis difficult resulting in delayed detection. Without early detection, the symptoms of this disease aggravate leading to gastrointestinal symptoms and organ dysfunction. In some cases, haemorrhagic manifestations may also occur in the infected individuals.

Diagnosis and Treatment

In the absence of confirmatory tests such as Polymerase Chain Reaction (PCR) or antigen- or antibody-based assays in the laboratory, it becomes a challenge for the health care professionals to differentiate BVD from other endemic febrile illnesses such as malaria. Outbreak control depends on early detection, isolation and care, contact tracing, safe burials and strong community engagement. Since there are no approved vaccines or specific treatments available for BVD, the current mortality rate of 44% to 46% for this disease poses a great threat to the affected communities.

Current situation of Ebola outbreak

Ebola, which spreads through contact with bodily fluids and causes a hemorrhagic fever, has killed more than 15,000 people in Africa over the past 50 years. As per the reports of international media outlets, the Ebola outbreak in DR Congo has spread to sixth province as death toll passes 2,100 with 4665 confirmed Ebola cases. The World Health Organization has already warned about its pace- the Ebola epidemic, already the deadliest in the country’s history, is spreading faster than any previous Ebola outbreak. Until now, five Congolese provinces had recorded cases: Ituri, which borders Uganda and South Sudan, North Kivu and South Kivu, Haut-Uélé and Tshopo. The risk of cross-border spread of this infection primarily to Uganda and South Sudan is very high. To make things worse, the response to contain this virus in the DRC is hampered by stretched health services, insufficient clean water and safe toilets. Some of the provinces where Ebola is present are densely populated and have only a weak government presence and largely lacking health infrastructure. North Kivu and South Kivu are also split by the front lines between the Congolese army and the anti-government armed group M23, backed by Rwanda, which has seized vast swathes of territory. This makes the conflict-ridden territory extremely prone to viral spread.

Should we be worried?

According to WHO official statement, the organization hopes to reverse the spread of this deadly virus in DRC within a span of three months with proper medical intervention. However, the pace with which it is spreading within DRC and bordering areas, it is quintessential to take some preventive measures. Since the globalization of the world was primarily responsible for Covid-19 pandemic, it is essential to have preparedness in advance. The healthcare authorities should establish proper communication channel with their counterparts in DRC to have real time data in hand. Similarly, a stock of screening kits should be maintained in the repository.

In our airports and seaports, no preventive measures are in place for the screening of any such disease. To put things into perspective, our agencies working in the airports handle body search of persons and their belongings with no protective gears. They do not even wear any mask while dealing with international flights. Most of the time, those passengers who present with clinical symptoms of disease like coughing, flu or fever tend to wear no mask. This puts the fellow passengers and the airport authorities at risk of many diseases. Therefore, the government should take proper measures in this regard. The seaport and airport personnel should be trained to wear masks and protective gear while handling the flights coming from DRC directly or indirectly. Proper screening booths should be installed having health care professionals equipped with medical kits and personal protective gear. There should be proper sanitization within the airports and seaports vicinities. All these measures will put us in a better position to prevent many contagious diseases beforehand. Prevention should be the top most priority of our health care system only then we can envisage a healthy future. In the end, let us hope the viral infection in DRC subsides before getting out of control.
