Blue-green Troubles: Algal Infections and their Impact on Public Health

Abstract

Margarida Dias

The tranquil appearance of blue-green algae belies the potential dangers lurking beneath the water's surface. Algal infections, specifically those caused by cyanobacteria, are emerging as a significant public health concern with far-reaching consequences. Blue-green algae, scientifically known as cyanobacteria, are microscopic organisms that can form dense colonies in freshwater bodies, such as lakes, ponds and reservoirs. While some cyanobacteria are harmless, certain species produce toxins that pose serious threats to both aquatic ecosystems and public health. Excessive growth of blue-green algae can lead to Harmful Algal Blooms (HABs), turning bodies of water into dense, greenish masses. These blooms can adversely affect water quality by depleting oxygen levels and producing toxins harmful to aquatic life. Furthermore, the toxins released by cyanobacteria during a bloom can have severe repercussions on the health of humans and animals alike.
