Brief Summary
The goal of this observational analytic study with a cohort desing is to evaluate the epidemiology, risk factors and clinical phenotype of headache during Influenza infection. The study will be done in collaboration with the Healthcare Sentinel Network of Castile and Leon (Red Centinela Sanitaria de Castilla y León, RCSCYL) and the National Influenza Center of Valladolid (CNGV). First, the historical data of the VIGIRA network of the 2010-2022 flu seasons will be analyzed, assessing the epidemiology and risk factors of headache during Influenza infection; and second, a study with a case series design with prospective follow-up will be carried out for the incident cases of the 2022-2023 and 2023-2024 Influenza seasons, evaluating the clinical phenotype and the duration of the headache.

Outcome Measures
Primary Outcomes (1)
Prevalence of headache as an influenza symptom
To calculate the proportion of patients who reported headache during the course of influenza infection
During each influenza season, starting on the season 2010 and until the season 2022, an average of 1 year per season
Secondary Outcomes (7)
Prevalence of headache as an influenza symptom - prospective
During the 2022-2024 influenza seasons, an average of 1 year per season
Predictors of headache as an influenza symptom
Including data from influenza seasons 2010-2022, an average of 1 year per season

Study Arms (1)
Patients with headache during the course of influenza
Patients with influenza infection who experience new-onset headache during the course of the disease, or a two-fold worsening of a prior headache disorder, according to the International Classification of Headache Disorders
Interventions
A trained physician will administer a structured questionnaire
Eligibility Criteria
The study population will be patients with a confirmed influenza infection. Patients belonging to a general practitioner or sentinel pediatrician quota who are evaluated in primary care (PC) by an IRA. Sample collection is performed in some patients who consult within 5 days from the onset of symptoms, especially if there is a clinical picture of fever.
You may qualify if:
- Confirmed diagnosis of influenza virus infection, using molecular techniques (PCR) or antigen test.
- Age older than 18 years old.
You may not qualify if:
- Critical medical situation that makes impossible the clinical interview and evaluation of clinical symptoms.
- Prior history of dementia or cognitive impairment that makes it difficult to assess patients or describe symptoms.
- Speech or language impairment, or insufficient comprehension of the Spanish language that makes evaluation difficult.
- Deceased during the course of the flu infection before they could be tested.
- Decline to be interviewed.
