[55] Because of the lack of infection-fighting neutrophils , a bacterial infection can spread rapidly; this fever is, therefore, usually considered to require urgent medical attention. [ 56 ]
Febrile seizures are due to fevers, [12] usually those greater than 38 °C (100.4 °F). [16] The cause of the fevers is often a viral illness. [1] The likelihood of a febrile seizure is related to how high the temperature reaches. [1] [6] Some feel that the rate of increase is not important [1] while others feel the rate of increase is a risk ...
It is unclear if rapid viral testing in the emergency department for children with acute febrile respiratory infections reduces the rates of antibiotic use, blood testing, or urine testing. [11] The relative risk reduction of chest x-ray utilization in children screened with rapid viral testing is 77% compared with controls. [11]
Approximately 2 weeks after initial HIV infection, with viral loads being high, an acute retroviral syndrome can present with fevers, rash and mono-like symptoms. [4] Immune reconstitution inflammatory syndrome is a common cause of FUO when a previously suppressed immune system is re-activated. The newly active immune system often has an ...
Meningism is a set of symptoms similar to those of meningitis but not caused by meningitis. [1] [3] [4] Whereas meningitis is inflammation of the meninges (membranes that cover the central nervous system), meningism is caused by nonmeningitic irritation of the meninges, usually associated with acute febrile illness, [1] [2] especially in children and adolescents. [2]
Febrile infection-related epilepsy syndrome (FIRES), is onset of severe seizures (status epilepticus) following a febrile illness in someone who was previously healthy. [1] The seizures may initially be focal; however, often become tonic-clonic. [4] Complications often include intellectual disability, behavioral problems, and ongoing seizures ...
