Insect-Borne Diseases and the Bugs That Carry Them

Insect-borne diseases, often transmitted through the bites of blood-sucking insects like mosquitoes and ticks, pose significant health risks to humans. These diseases are caused by various viral and bacterial pathogens carried by these insects and can lead to a wide range of symptoms. Common symptoms of insect-borne diseases include fever, chills, headache, sore muscles, skin rash, nausea, and stomach pain, some cases can escalate to more severe symptoms. These diseases underscore the importance of preventive measures such as wearing protective clothing, using insect repellents, and eliminating breeding sites for these insects to reduce the risk of infection.
