If you are studying for a medical school exam, you are sure to be tested on the topic of vector-borne diseases. The vast majority of these infections are caused by bacteria or viruses, but some are also carried by insects, such as mosquitoes. The most common vector-borne disease is malaria, which is spread by mosquitoes. It causes 219 million cases worldwide and results in 400,000 deaths annually. It usually affects children under 5 years old. Dengue is the most common viral infection spread by Aedes mosquitoes and causes 96 million symptomatic cases and 40,000 deaths each year.
There are four main types of vector-borne diseases: chikungunya, dengue, and West Nile. The symptoms of these illnesses vary widely from one person to the next, but they generally begin with a fever, chills, joint pain, or rash. The chikungunya and dengue viruses are similar. In the former, they can be treated by treating the patient’s symptoms, whereas dengue requires laboratory confirmation.
The symptoms of these infections include fever, chills, headache, nausea, joint pain, and rash. In areas of the world where dengue is prevalent, laboratory confirmation is required to determine a diagnosis. In thermal fogging, a minimum of one liter of insecticide formulation is applied per square meter. Technical malathion is the insecticide used. Thermal fogging uses no diluent.
The most common symptoms of dengue include a rash and fever. The diagnosis is difficult to make unless the patient has been exposed to the disease for some time. Other symptoms of chikungunya may be subtle, such as joint pain or nausea. In some cases, the disease may not be apparent, but the doctor should seek laboratory confirmation. There are many vaccines available to treat dengue, and a new treatment for chikungunya has been approved in several countries.
The Division of Vector-Borne Diseases is an international and national leader in the field of vector-borne diseases. The division is comprised of entomologists, epidemiologists, microbiologists, veterinarians, and virologists. The Division is dedicated to the study of these diseases and is committed to ensuring that they do not affect human health. You can learn more about these important topics in the following video.
You can also learn about vector-borne diseases during your clinical rotation. It is important to know about these diseases because they can affect you and your family. The first step in the treatment of vector-borne diseases is to prevent exposure to the risk factors. The Division of Vector-Borne Diseases has staff members who specialize in entomology, epidemiology, microbiology, animal science, and public health.
