Tick paralysis: first zoonosis record in Egypt.

Area of Science:

• Veterinary Neurology
• Parasitology
• Public Health

Background:

• Tick paralysis is a significant veterinary concern, rarely affecting humans, caused by neurotoxins secreted by ticks during feeding.
• The condition, while having geographical tendencies, is globally distributed and can present with symptoms mimicking other neurological disorders.

Purpose of the Study:

• To report the first documented cases of tick paralysis in children in Egypt.
• To differentiate tick paralysis from other neurological diseases presenting in rural Egyptian children.

Main Methods:

• Clinical assessment of four children presenting with neurological symptoms.
• Exclusion of other potential diagnoses including rabies, myasthenia gravis, botulism, and diphtheritic polyneuropathy through clinical and laboratory data.
• Identification of ticks infesting the affected children and their domestic animals.

Main Results:

• Four children in Giza Governorate, Egypt, were diagnosed with tick paralysis.
• Clinical presentations were initially confused with other neurological conditions common in rural areas.
• Ticks identified included Rhipicephalus sanguineus, Hyalomma dromedarii, Hyalomma anatolicum excavatum, and Haemaphysalis sp. from associated animals.

Conclusions:

• This study represents the first recorded instance of tick paralysis in Egypt.
• Accurate diagnosis requires considering tick exposure, especially when clinical signs are ambiguous and other diseases are ruled out.
• Highlights the importance of veterinary and public health surveillance for tick-borne illnesses in new geographical regions.
