A current outbreak of the Marburg virus, also referred to as the ‘bleeding eye’ virus, has triggered a world well being alert. With not less than 15 fatalities and a whole bunch of infections reported throughout 17 African nations, together with Rwanda, well being officers are urging travellers to train warning.
In line with a report by The Unbiased, “In October the WHO warned towards all journey to Rwanda, whereas the UK’s nationwide public well being company warned travellers visiting Rwanda to keep away from a number of actions similar to taking part in burial rituals or coming into contact with wild animals.”
Dr Jagadish Hiremath, public well being mental, tells indianexpress.com, “The ‘bleeding eye’ virus, formally often known as the Marburg virus, is a extremely infectious and sometimes deadly virus belonging to the identical household because the Ebola virus (Filoviridae). First recognized in 1967 throughout outbreaks in Germany and Yugoslavia linked to laboratory monkeys imported from Uganda, it has since prompted sporadic outbreaks in Africa.”
What makes it lethal
In line with Dr Hiremath, “The Marburg virus causes extreme viral hemorrhagic fever, with a mortality charge starting from 23% to 90%, relying on the outbreak and out there healthcare amenities. Loss of life typically happens inside 8–9 days of symptom onset, usually as a result of extreme blood loss or multi-organ failure.”
Early signs embody excessive fever, extreme headache, muscle ache, and malaise. Because the illness progresses, sufferers expertise vomiting, diarrhea, stomach ache, and important bleeding (each inner and exterior). The time period ‘bleeding eye virus’ comes from bloodshot or hemorrhaging eyes noticed in some instances.
Dr Hiremath provides that the virus replicates quickly, overwhelming the immune system and inflicting widespread irritation and vascular harm, resulting in shock and organ failure.
“Marburg is transmitted via direct contact with bodily fluids (blood, saliva, sweat, urine, vomit) of contaminated people or contaminated surfaces. This ease of transmission makes controlling outbreaks extraordinarily difficult,” he notes.

Why is it troublesome to develop a vaccine or therapy for it?
Creating vaccines or therapies for the Marburg virus is difficult as a result of a number of components, says Dr Hiremath, that are:
Rarity and Sporadic Outbreaks: The virus happens in remoted outbreaks, limiting alternatives for large-scale analysis and medical trials. This sporadic nature additionally reduces pharmaceutical corporations’ incentives to put money into vaccine growth.
Advanced Pathophysiology: The virus targets a number of organs, inflicting widespread harm that’s troublesome to counteract. Its capability to suppress the immune system additional complicates therapy.
Lack of Established Therapies: Not like another viruses, no broadly permitted antiviral medicine particularly focusing on Marburg exist. Analysis into promising candidates, like monoclonal antibodies and antiviral brokers, is ongoing however stays in early phases.
Useful resource Constraints in Affected Areas: Outbreaks typically happen in resource-limited areas, making implementing subtle therapy protocols or conducting medical trials difficult.
Comparable Challenges as Ebola: The Marburg virus shares many traits with Ebola, for which vaccines and coverings have been solely not too long ago developed after many years of analysis. Marburg’s rarity additional delays comparable progress.
How can travellers to affected areas defend themselves?
Dr Hiremath suggests avoiding contact with contaminated people or high-risk areas like caves with Rousettus bats and bushmeat sources to stop viral hemorrhagic fever. Observe strict hygiene by washing arms typically and avoiding face-touching. Use protecting gear similar to masks and gloves, keep knowledgeable via WHO and CDC updates, and search fast medical consideration if signs like fever or muscle ache seem after publicity to high-risk environments.
May the Marburg virus outbreak result in a world well being disaster?
Dr Hiremath informs that Marburg virus outbreaks are “usually localised and fewer more likely to trigger world pandemics” than airborne viruses like COVID-19, however the excessive fatality charge, human-to-human transmission, and elevated world journey pose important dangers. Efficient containment depends on speedy prognosis, isolation, contact tracing, public consciousness, worldwide collaboration, and advancing analysis in diagnostics and coverings to stop widespread transmission and handle future outbreaks.
