The patient presented with a fever, cough, runny nose, conjunctivitis, and rash
Differential Diagnosis
1. Measles:
The patient presented with a fever, cough, runny nose, conjunctivitis, and rash; They have recent travel to Europe about 10 days ago, which is within the incubation period for measles.; absence of rash on palms and soles is characteristic. The absence of rash on the palms and soles is characteristic of measles.
2. Kawasaki Disease:
In this case, the patient’s fever lasts four days, indicating Kawasaki disease. He also have bilateral conjunctival injection, mild cough, and cervical lymphadenopathy. Other symptoms, like red lips, swollen hands and feet, are not mentioned in the physical examination. Regardless of color or ethnicity, Kawasaki disease can affect children. Children from East Asian or Asian ancestry families are more likely to experience it. Most kids with Kawasaki disease are under the age of five. Boys experience it more frequently than girls do.
3. Rubella:
This causes fever, rash, lymphadenopathy, and spreads to the face, trunk, and extremities. Recent travel to Europe may increase the child’s risk of exposure due to outbreaks in different regions. The first symptom of rubella is typically a rash that is pink or light red in color and forms uniformly colored patches. It can itch for up to three days and lose afflicted skin in tiny flakes as it heals.
Primary Diagnosis
The most likely cause is measles. The presence of a recent travel history at Europe, together with the symptoms of fever, cough, runny nose, pinkeye (conjunctivitis), and the distinctive rash that extends from the head to the trunk and extremities, strongly suggests measles. On the physical findings of the skin it is Erythematous, blanching macular-papular rash from hairline to toes.
According to WHO: Since the beginning of 2023, measles cases have been reported in 17 nations in the WHO European Region. By the end of February, there had been more cases reported than there had been in the entire year of 2022 (almost 900).
Pathophysiology
The measles virus, a highly contagious RNA virus from the Paramyxovirus family, is what causes the disease. Measles is a systemic infection primarily affecting alveolar macrophages or dendritic cells. After replication in the lung, the virus spreads to lymphoid tissues, leading to a systemic infection. A second viremia occurs 5-7 days after infection, where infected lymphocytes and dendritic cells migrate into the subepithelial cell layer and transmit measles toepithelial cells. The virus is released into the respiratory tract. It spreads quickly in places with low immunization rates and is mostly transferred by respiratory droplets. The characteristic rash and other systemic symptoms are brought on by the virus’s initial replication in the respiratory tract, which spreads to the rest of the body.
Management
Confirm diagnosis by performing laboratory tests, providing supportive care, isolating the patient, ensuring immunization status, monitoring complications, and providing prompt medical intervention.
Inform public health authorities about the diagnosis and provide timely medical intervention.
Monitor the patient’s progress and ensure symptom resolution.
Educate the patient’s mother about the importance of vaccination and the risks of not vaccinating.
Refer the patient to a pediatric infectious disease specialist or general pediatrician for evaluation, diagnosis, and appropriate management of viral infections.
Schedule follow-up appointments to ensure the patient’s well-being.
Provide catch-up immunizations after child’s recovery.
