Insects and spiders: infestations and bites

Area of Science:

• Medical Entomology
• Public Health
• Infectious Diseases

Background:

• Insect bites and infestations continue to cause widespread human suffering despite available treatments.
• The global scabies pandemic persists, indicating challenges in control and eradication.
• Arthropod vectors, including insects and spiders, pose significant and evolving public health threats.

Purpose of the Study:

• To highlight the persistent and increasing public health burden of insect bites and infestations.
• To underscore the role of arthropods as vectors for serious infectious diseases.
• To draw attention to the expanding geographic range of medically significant arthropods.

Main Methods:

• Literature review of current epidemiological data on insect-borne diseases.
• Analysis of trends in the incidence of scabies, lice, and bed bug infestations.
• Assessment of the potential for arthropod-borne transmission of viral and parasitic pathogens.

Main Results:

• Scabies infestations remain a significant global health problem.
• Bed bugs are increasingly implicated in the transmission of Hepatitis B and potentially African acquired immune deficiency syndrome (AIDS).
• Incidences of head lice and pubic lice are increasing, with pubic lice often co-occurring with sexually transmitted diseases.

Conclusions:

• Insect bites and infestations represent a substantial and growing public health concern.
• Arthropods like bed bugs pose emerging threats for disease transmission, including serious viral infections.
• The geographic distribution of venomous spiders is expanding, increasing the risk of bites in new regions.
