Respiratory
tract infections (RTIs) are a group of infections that affect the respiratory system, which includes the organs
and tissues involved in breathing. Typically caused by viruses, bacteria, or
fungi, RTIs manifest with symptoms like coughing, sneezing, nasal congestion,
and difficulty breathing. Prevention and
management of respiratory tract infections often involve good hygiene
practices, vaccination (such as the flu vaccine), and, in some cases, antiviral
or antibiotic medications.
