Both viruses and bacteria cause infections, but antibiotics only work against bacteria
Viral Infections
- Colds, flu, croup, laryngitis, chest colds (bronchitis) and most sore throats are caused by viruses.
- Are more contagious than bacterial infections.
- If more than one person in the family has the same illness, it is most likely a viral infection.
- Can make you just as sick as bacterial infections.
- Usually get better in 4-5 days but it may take as long as three weeks to fully recover.
Antibiotics do not work against most viruses
Bacterial Infections
- Are less common than viral infections.
- Do not spread as easily from one person to another as viral infections.
- Cause infections such as pneumonia and strep throat.
