The Karnataka health department has proactively issued a set of comprehensive guidelines to all districts across the state, mandating preparations for an anticipated increase in seasonal influenza cases. This directive follows a formal advisory from the National Centre for Disease Control (NCDC), projecting a surge in infections during the period from January to March 2026.
Enhanced Surveillance and Mandatory Testing Protocols
Under the new guidelines, district health authorities have been instructed to significantly intensify their monitoring efforts. The focus will be on tracking cases of Influenza-Like Illness (ILI) and Severe Acute Respiratory Infection (SARI). A critical component of the strategy involves mandatory testing of respiratory samples at designated laboratories.
The department has specified that 5% of all ILI samples and 100% of all SARI samples must be sent for analysis. These tests will be conducted at nine specialized influenza laboratories established across Karnataka. Key facilities include the Bangalore Medical College and the National Institute of Virology (NIV) branch located in Bengaluru.
Stockpiling Essentials and Protecting Vulnerable Groups
To ensure an effective response, districts have been ordered to verify and maintain adequate reserves of crucial medical supplies. The checklist includes the antiviral drug Oseltamivir, personal protective equipment (PPE) for healthcare workers, N95 masks, and a sufficient number of ventilators for critical care.
Vaccination has been highlighted as a primary preventive measure. The health department has emphasized that immunization campaigns should prioritize healthcare workers, infants, the elderly, pregnant women, and individuals with compromised immune systems. Protecting these high-risk demographics is considered essential to reducing severe outcomes and mortality.
Public Awareness and Digital Reporting
Beyond medical readiness, the guidelines call for a robust public communication strategy. District authorities are tasked with intensifying Information, Education, and Communication (IEC) campaigns. The goal is to encourage the public to recognize symptoms early and seek prompt medical attention.
A key tool in this effort is the Integrated Disease Surveillance Programme–Integrated Health Information Platform (IDSP–IHIP) portal. Health officials will promote the use of this digital platform for early reporting and real-time tracking of cases, enabling a faster and more coordinated state-wide response.
Seasonal influenza, a contagious viral infection affecting the respiratory system, spreads through droplets from coughs or sneezes and contact with contaminated surfaces. An infection typically lasts between five to seven days, with common symptoms including fever, chills, cough, sore throat, and body aches. The state's pre-emptive measures aim to mitigate the impact of the expected seasonal wave and prevent the healthcare system from being overwhelmed.
