Why does molluscum contagiosum cause skin bumps?

Short answer
Molluscum contagiosum causes skin bumps when the virus infects surface skin cells, making them multiply into small, smooth, dome-shaped lesions.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

How the bumps develop
Skin Bumps is a common presentation of Molluscum Contagiosum. The lesions are often pearly, flesh-coloured, or pink and may have a small central dip. They can occur on the trunk, arms, legs, or face. The virus spreads through close skin contact and can also move from one body area to another when a person scratches or rubs a lesion. Several bumps may appear over time, and surrounding skin can become itchy or inflamed as the immune system reacts. Appearance alone cannot confirm the diagnosis because other bumps can look similar.
Reducing spread and irritation
Avoid scratching, shaving over, or picking the bumps. Wash hands after touching the area and do not share towels, razors, or personal items that contact affected skin. Cover lesions when practical during close contact, swimming, or sports, following local clinical advice. A clinician can discuss observation or treatment based on age, location, eczema, immune health, and the number of lesions. Do not apply harsh chemicals without guidance.
When a clinical review matters
Arrange an assessment if bumps are near the eyes or genitals, become very painful, ooze, or are surrounded by spreading redness. Review is also helpful when lesions are numerous, persistent, repeatedly scratched, or occurring in someone with reduced immune defence. A clinician can confirm the cause and check for secondary irritation or infection.
Questions to discuss
Ask whether the appearance fits molluscum, how to protect household contacts, and whether eczema around the lesions needs separate care. Ask which treatment is appropriate for the location and how to care for the skin afterward.

Questions people ask
Can molluscum bumps spread to other skin?
Yes. Scratching or rubbing can move the virus from one lesion to nearby skin, so keeping hands and nails clean helps limit spread.
Should molluscum bumps be squeezed?
No. Squeezing can injure the skin and spread the virus or introduce bacteria.
