In the labyrinth of the human body, a multitude of microscopic life forms thrive, shaping our health, emotions, and overall wellbeing. Among these microorganisms, there exists a pantheon of villains, known as pathogens, poised to compromise our health at the slightest opportunity. Let’s venture into the world of these pathogens, examining their role in diseases like endometriosis, measles, and HIV, while also delving into how the body responds to their insidious invasions.
In the vibrant arena of Earth’s biodiversity, one of the most enigmatic and perilous phenomena is the transmission of diseases by organisms. The perpetrators are often tiny creatures that stealthily invade our bodies, acting as transporters for deadly pathogens. One such diminutive creature is the ‘Aedes aegypti’ mosquito, the primary vector of dengue fever.
The COVID-19 pandemic has left an indelible mark on global health, with its impact extending far beyond the acute phase of the disease. A recent Swiss study published in the British Medical Journal (BMJ) has shed light on the long-term effects of COVID-19 in unvaccinated individuals, revealing a worrying trend.
Nail bed injuries in children are a widespread issue, with over 10,000 operations performed each year in the UK alone. Often caused by a child’s fingertip being crushed in a closing door, these injuries were the focus of a 2017 information campaign by BAPRAS (British Association of Plastic Reconstructive and Aesthetic Surgeons) to raise awareness and prevent accidents.
Last year, health experts worldwide were puzzled by reports of severe, unexplained hepatitis in previously healthy children. A recent study conducted by the University of California, San Francisco (UCSF) has shed light on this mysterious outbreak of acute severe hepatitis that affected children in the United States and 34 other countries in spring 2022.
Researchers have found that global warming is causing the spread of a deadly flesh-eating bacteria, Vibrio vulnificus, along the northeastern coast of the United States. The bacteria, which is found in warm, shallow coastal waters, can infect a person through a cut or insect bite during contact with seawater.
Over the past three years, SARS-CoV-2 has continued to evolve by accumulating genetic variations. A co-infection of multiple lineages of the virus could result in recombinations between genomes that can give rise to chimeric genomes or recombinants. While most recombinations may not give rise to viable viruses, a rare possibility exists where recombination could result in the creation of a new lineage of the virus with better functional capabilities than either of the parent lineages.
