The COVID-19 pandemic significantly altered how patients access medical services globally. Recent research highlights a concerning shift in dengue healthcare seeking behavior during and after the outbreak. While the pandemic overwhelmed health systems, it also created a "smokescreen" effect. Clinicians often misattributed febrile illnesses to COVID-19. Consequently, this led to critical delays in dengue diagnosis and management.
A sentinel surveillance study in Puerto Rico compared data from 2014–2020 to 2020–2023. Researchers found that the median age of patients seeking care for dengue increased during the latter period. Furthermore, the duration of illness before presenting to a healthcare facility shifted significantly. This change reflected how communities perceived risk and accessible care. Therefore, these delays can lead to a higher risk of severe complications. Such complications include plasma leakage and dangerous hemorrhagic manifestations.
In India, where dengue is hyper-endemic, clinicians observed similar trends. Many patients avoided hospitals due to fear of COVID-19 infection. Others found that diagnostic resources were redirected to pandemic needs. Therefore, clinicians must remain vigilant during monsoon seasons. Early identification of "warning signs" is essential for patient survival. These signs include persistent vomiting, abdominal pain, and mucosal bleeding. Additionally, the National Guidelines for 2023 emphasize that early fluid management is the cornerstone of treatment. Because symptoms overlap with other viral infections, laboratory confirmation is vital. Providers should use NS1 antigen or IgM ELISA for timely intervention.
The pandemic demonstrated that health-seeking patterns are fragile. By understanding these shifts, providers can better educate patients on when to seek immediate care. Continuous surveillance and public awareness are necessary. These efforts ensure that seasonal dengue outbreaks do not result in preventable deaths due to delayed presentation.
The overlap of symptoms like fever and body ache often led to misdiagnosis. Additionally, many patients delayed seeking care due to lockdowns or fear of contracting COVID-19 in hospitals.
Patients should seek urgent medical attention if they experience severe abdominal pain, persistent vomiting, rapid breathing, or bleeding gums, as these indicate a progression toward severe dengue.
