BIRD FLU

Bird flu is an influenza virus that mainly infects birds but can occasionally spread to humans and other animals. Some strains, such as H5N1, can cause severe illness and are closely monitored for their pandemic potential.

HANTAVIRUS

Hantavirus is a group of viruses carried by rodents and transmitted to humans through contact with infected rodent droppings, urine, or saliva. Infection can lead to serious respiratory or kidney-related diseases.

Featured infographic about the “Missing Millions” in tuberculosis (TB), showing that 2 million TB patients are missing from global tracking annually and that missing TB cases increased from 2.9 million in 2019 to 4.2 million in 2020 during the COVID-19 pandemic. The image includes a silhouette crowd, infected lungs illustration, and the message “Missing Today. Infecting Tomorrow. Find. Treat. End TB.”

TUBERCULOSIS

Tuberculosis (TB) is a bacterial disease caused by Mycobacterium tuberculosis, primarily affecting the lungs. It spreads through the air when an infected person coughs or sneezes and remains one of the world’s leading infectious killers.

NOROVIRUS

Norovirus is a highly contagious virus that causes acute gastroenteritis, leading to symptoms such as vomiting, diarrhea, stomach cramps, nausea, and sometimes fever. It spreads easily through contaminated food, water, surfaces, or close contact with infected individuals.

A featured graphic with a white background titled 'A Potential New Trigger for Alzheimer's Disease'. It features two main boxes comparing cell transport side-by-side. The left box, 'Healthy Brain Cell Transport,' depicts tau proteins successfully stabilizing tracks so nutrients and materials move freely. The right box, 'Disrupted & Tangled,' shows amyloid beta displacing tau, causing cell transport to break down and tau proteins to clump into a chaotic purple web labeled 'Tau tangles'. A summary line at the bottom reads, 'A focus on cell transport as a key driver of disease'.

ALZHEIMER’S DISEASE

Alzheimer’s disease is a progressive neurodegenerative disorder that gently strips away memory, thinking skills, and the ability to carry out simple daily tasks. It is the most common cause of dementia among older adults, gradually impacting the parts of the brain that control thought, memory, and language.
