Unlike mild respiratory infections, influenza can cause high fever, extreme tiredness, body pain, and respiratory discomfort. In severe cases, it can lead to pneumonia or worsen existing medical conditions such as asthma, diabetes, or heart disease.

• Can infect both humans and animals
Influenza Type B

• Often goes unnoticed
Understanding these types helps doctors predict flu patterns and prepare vaccines accordingly.
