The recent unfortunate incidence of approximately 100 students coming into contact and developing skin infections from Nairobi flies in East Sikkim has sparked conversations about this peculiar species. This article offers a simplified insight into the Nairobi flies, their historical outbreaks, and effects on human beings.
Understanding Nairobi Flies
Nairobi flies are an insect species native to East Africa. Known traditionally as Kenyan flies or dragon bugs, these beetle-like creatures belong to two species: Paederus Eximius and Paederus sabaeus. Sporting a distinct orange and black colour, these insects gravitate towards areas with high levels of rainfall, a characteristic that recently drew them to Sikkim.
Similar to most insects, bright lights attract Nairobi flies. However, what sets them apart is their ability to adapt and thrive in diverse environmental conditions, from the lush forests of East Africa to the monsoon-hit plains of India.
A Brief History of Outbreaks Linked to Nairobi Flies
Historically, Nairobi flies have caused significant outbreaks in Kenya and various other parts of Eastern Africa. They have been brought to larger populace by heavy rains, such as the one in 1998, which saw an unusual influx of these insects into the local communities.
However, outbreaks linked to these insects are not confined to Africa. Over the years, several countries outside Africa, including India, Japan, and Paraguay, have also reported similar infestations.
The Impact of Nairobi Flies on Human Beings
Contrary to popular belief, Nairobi flies do not bite humans. The danger they pose to humans lies in the form of a potent acidic substance called Pederin, released when they are disturbed during their stay on human skin.
While not dangerously toxic, Pederin can cause irritation and burns on human skin upon contact. It typically results in lesions, unusual marks, or discoloration of the skin. Despite not posing a severe health risk, exposure to this substance can result in discomfort and necessitate medical attention.
The Recent Nairobi Fly Outbreak in East Sikkim
Recently, East Sikkim experienced an unfortunate Nairobi fly outbreak that affected approximately 100 students. The period of high rainfall in the area attracted a large population of these insects, resulting in widespread skin infections among the students from their contact with the flies.
This event serves as a crucial reminder of the potential impact of Nairobi flies on humans, highlighting the necessity for early detection and increased public awareness about these largely overlooked insects.
Overall, the Nairobi flies, while native to East Africa, have emerged as a global concern due to their ability to thrive in diverse climatic conditions and their potential to cause discomfort among humans through the release of Pederin. It underscores the need for continued research and public health education to prevent similar outbreaks in the future.
