Introduction

Fever usually refers to an elevated body temperature. Recurrent fever in a 1-year-and-4-month-old baby may be related to low immunity, upper respiratory tract infection, gastroenteric flu, or other causes. It could also be associated with conditions such as tuberculosis or hyperthyroidism. It is recommended to visit the pediatric department of a hospital as soon as possible, identify the underlying cause, and receive appropriate treatment.

Fever usually refers to an elevated body temperature. Recurrent fever in a 1-year-and-4-month-old baby may be related to low immunity, upper respiratory tract infections, gastroenteric cold (gastrointestinal viral infection), and other causes.

1. Low resistance: The immune system of a 1-year-and-4-month-old baby has not yet fully developed. When pathogens such as bacteria or viruses invade the body, immune cells may fail to promptly recognize and eliminate them. This allows the pathogens to multiply extensively inside the body, triggering inflammatory responses that affect the normal function of the body's temperature regulation center, leading to fever.

2. Upper respiratory tract infection: Babies of this age are particularly susceptible to upper respiratory tract infections when exposed to cold conditions. If the infection is not completely treated and persists chronically, it may lead to recurrent fever in the baby, often accompanied by symptoms such as coughing and phlegm production.

3. Gastroenteric cold: Pathogens such as respiratory syncytial virus and adenovirus can enter the baby's body and cause chronic inflammatory reactions. These not only disrupt gastrointestinal function but also trigger systemic symptoms, potentially resulting in nausea, vomiting, diarrhea, and recurrent fever.

Recurrent fever in a 1-year-and-4-month-old baby may also be associated with other conditions such as tuberculosis or hyperthyroidism. It is recommended to seek prompt medical evaluation at a pediatric department in a hospital to determine the underlying cause and receive appropriate treatment.

After being scratched by a small hamster and receiving an injection, can I take fever-reducing medicine if I develop a fever?

If the fever exceeds 38.5°C, or is accompanied by significant discomfort such as headache, muscle aches, and fatigue, taking antipyretic medications (such as acetaminophen tablets or ibuprofen suspension) can help relieve symptoms and prevent potential adverse effects of high fever on the body. Antipyretics do not interact with vaccines administered after scratches or wounds, nor do they interfere with the vaccine's ability to induce an immune response; therefore, there is no need to worry about drug interactions.
