Zoonosis: Update on Existing and Emerging Vector-Borne Illnesses in the USA

Area of Science:

• Arthropod-borne diseases
• Epidemiology
• Public Health

Background:

• Mosquitoes and ticks transmit numerous pathogens.
• Geographic ranges of vectors are shifting.
• Emerging infectious diseases pose significant public health challenges.

Purpose of the Study:

• To review mosquito- and tick-borne diseases in the Western Hemisphere.
• To highlight emerging diseases and vector distribution changes.
• To inform healthcare providers about current trends.

Main Methods:

• Literature review of recent studies.
• Analysis of geographic shifts in vector populations.
• Synthesis of emerging disease data.

Main Results:

• Vectors are expanding into new territories due to climate change.
• Zika virus poses a risk for fetal abnormalities.
• West Nile Virus is now endemic in many areas.
• Lyme disease and other tick-borne illnesses are increasing in previously unaffected regions.

Conclusions:

• Healthcare providers must consider a wider range of diseases based on geographic location.
• Patients traveling to endemic areas need counseling on prevention.
• Prompt treatment for severe tick-borne illnesses is crucial, without awaiting culture confirmation.
