What is the world’s biggest killer? It's ischaemic heart disease, responsible for 16% of the world’s total deaths - that is equal to 9.5 million deaths in 2023. Stroke and chronic obstructive pulmonary disease were the second and third leading causes of deaths in 2023, responsible for approximately 11% (6.8 million) and 6% (3.6 million) of total deaths, respectively. 💔 Ischaemic heart disease is a condition where the heart muscle receives less blood flow and oxygen because the coronary arteries are narrowed or blocked. 🧠 Stroke is a medical emergency that occurs when blood flow to the brain is interrupted, either due to a blockage or bleeding. 🫁 Chronic obstructive pulmonary disease (COPD) is a common lung disease causing restricted airflow and breathing problems. It is sometimes called emphysema or chronic bronchitis. New global health estimates bit.ly/4z5Vfsx

When governments tax harmful products - tobacco, alcohol and sugary drinks - significantly, people consume less, lives are saved and public revenues rise. Small, irregular tax adjustments are too easily swallowed by inflation or manipulated by industry. Countries need predictable and ambitious increases that make these harmful products progressively less affordable bit.ly/4hV8ruE

Wildfires burn more than wood. The smoke releases harmful gases and tiny particles into the air that are toxic to breathe in. As wildfires spread, they're increasingly burning homes, roads, power lines and other structures. When materials and structures burn, they add even more harmful chemicals to the smoke. The ash left behind can also be dangerous; it may contain toxic metals, asbestos and other harmful chemicals.

#Rabies isn't a dog-only problem. Cats, bats, foxes, jackals. Any mammal can carry the virus and pass it on through a single bite or scratch. If it happens to you, get to a clinic fast. Once symptoms appear, it's almost always too late. #WorldRabiesDay

Protecting people starts with protecting our animals. Regular vaccination of dogs and other pets helps stop rabies at its source and prevents transmission within communities. If a person is bitten or scratched by an animal that may have #rabies, immediate access to appropriate medical care and post-exposure vaccination can save their life. Vaccinate pets. Act quickly after exposure. Together, we can stop rabies transmission. #WorldRabiesDay
