Types of Fever

Types of Fever

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:

Patterns of Fever

Patterns of Fever

Before understanding the types and patterns of fever, it is essential to know its phases.

Methods of reducing fever

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Summary

Tick-borne relapsing fever, a Borrelia-caused zoonosis, is often misdiagnosed. Prompt diagnosis via spirochete identification in blood smears is crucial for effective antibiotic treatment.

Background:

Tick-borne relapsing fever (TBRF) is a zoonotic disease caused by Borrelia spirochetes transmitted by ticks.
This life-threatening illness is frequently misdiagnosed due to non-specific symptoms.

Observation:

A 54-year-old man presented with isolated fever after hiking in Morocco.
Initial assessments revealed inflammatory syndrome and liver dysfunction, with negative blood cultures and serology for HIV and Lyme disease.
The patient experienced recurrent fever episodes, prompting malaria suspicion and subsequent blood smear analysis.

Findings:

Microscopic examination of May-Grünwald Giemsa stained blood smears revealed Borrelia spirochetes.
This confirmed the diagnosis of tick-borne relapsing fever.
The patient responded well to treatment withcycline drugs.

Implications:

TBRF should be considered in patients with intermittent fever and non-specific clinical or laboratory findings, especially with relevant epidemiological exposure.
Accurate diagnosis relies on identifying spirochetes in blood or cerebrospinal fluid smears.
Increased awareness and diagnostic vigilance are necessary for managing this underrecognized disease.
