The Deadly Killer Among Us: The Silent Devastation of Mosquitoes

💀Mosquitoes, weighing a barely measurable 2 and 2 milligrams, carry diseases that have killed half of all people who have ever lived.

🌍Mosquitoes transmit malaria, which kills almost half a million people and infects over 200 million each year.

🦟Mosquitoes are the most ancient foes of humanity, dating back millions of years. They have changed human history and affected native populations.

🧬Evolutionary pressures from malaria have led to mutations in human DNA, such as the sickle cell trait, which provides some protection against the disease.

💰Malaria takes a toll on human health, social and economic costs. The estimated direct and indirect costs amount to about $12 billion per year.

Why are mosquitoes considered the deadliest killers?

—Mosquitoes carry diseases like malaria, which have killed half of all people who have ever lived. They transmit these diseases when they bite and inject pathogens into the bloodstream.

How many people are affected by mosquito-borne diseases each year?

—Mosquito-borne diseases, such as malaria, infect over 200 million people and kill almost half a million people annually.

How have mosquitoes changed human history?

—Mosquitoes have affected human history by decimating native populations when diseases like malaria were introduced to new continents. They have shaped human DNA and led to mutations like sickle cell trait.

What are some evolutionary responses to malaria?

—Evolutionary responses to malaria include mutations like the sickle cell trait, which provide some protection against the disease. However, these mutations can have other health implications.

What are the economic costs of mosquito-borne diseases?

—Mosquito-borne diseases, such as malaria, have significant economic costs. The direct costs of illness, treatment, and prevention, along with the indirect costs of lost economic growth, amount to billions of dollars each year.
