Is Cellulitis Contagious? Can You Catch It From Someone Else?
Wondering if cellulitis is contagious? Learn whether cellulitis can spread from person to person, who is most at risk, and how the infection develops.
Is cellulitis contagious? Can you catch it from someone else?
In our experience, many people wonder whether close contact with someone suffering from cellulitis could pose a risk. In most cases however, cellulitis is not considered contagious and unlike infections such as colds, flu or some stomach bugs, it doesn’t usually spread from person to person through everyday contact.
Why it usually doesn’t spread between people
The bacteria that commonly cause cellulitis often live harmlessly on the skin or in the environment so simply being near someone with cellulitis won’t usually lead to infection. You cannot normally catch cellulitis by touching someone for example, sharing a room with them or having casual contact. The infection occurs within the affected person's skin and deeper tissues rather than sitting on the surface waiting to spread.
Who may be more prone to catching cellulitis?
People with weakened immune systems, chronic skin conditions or circulation problems may be more vulnerable to infections in general, but cellulitis itself is still not considered something that is easily passed from one person to another. However, it’s best to avoid direct contact with a sufferer’s open wounds or areas that are actively leaking fluid. Washing hands after dressing changes or wound care is also a sensible precaution.
Certain factors increase the likelihood of developing cellulitis. These include diabetes, poor circulation, lymphoedema, chronic swelling, eczema and injuries that damage the skin barrier.
People who have had cellulitis before may also be more likely to experience it again, particularly if the underlying cause has not been addressed.
Final thoughts
Cellulitis is a bacterial skin infection, but it is not generally considered contagious. You cannot usually catch it through normal social contact, touching someone or spending time with them.
The infection develops when bacteria enter through damaged skin rather than being passed directly from person to person. While good hygiene remains important, there is usually no need to avoid someone simply because they have cellulitis.
