Key differences between seasonal flu and RSV: symptoms and high-risk groups

The Saudi Health Ministry’s 'Live Well' platform has highlighted the key differences between seasonal flu and respiratory syncytial virus (RSV). Both conditions have distinct symptoms, risk groups, and preventive measures.

Seasonal flu symptoms appear suddenly and can be severe. They include high fever, muscle aches, and persistent coughing. Vulnerable populations include older adults, children under five, pregnant women, individuals with chronic illnesses, and those with weakened immune systems or severe obesity. The Ministry recommends annual vaccination for flu prevention, with eligibility typically starting at a certain age in months, as determined by health guidelines.

RSV symptoms, on the other hand, develop more gradually. They may include a runny nose, coughing, wheezing, and a decreased appetite. High-risk groups for RSV complications are infants—particularly those under six months—premature infants, older adults (especially those aged 75 and above), and individuals aged 50 and over with chronic medical conditions. Targeted immunization is available for some of these high-risk groups, as recommended by health authorities.

Both seasonal flu and RSV can be mitigated through preventive measures. These include frequent handwashing, covering the mouth and nose while coughing or sneezing, and maintaining good hygiene practices. Vaccination appointments can be scheduled through the Sehhaty app, making it easier for individuals to protect themselves from these respiratory illnesses.
