How Germs and Infections Spread in GP Surgeries and Clinics

Direct contact involves transfer through contact between people. Indirect contact involves an intermediate object or surface, such as shared equipment. For example, hands may become contaminated during a task and then touch another object. Whether that leads to infection depends on the organism, exposure and person involved.

The NHS National Infection Prevention and Control Manual sets out standard precautions and additional precautions for particular risks. These arrangements should guide practice procedures. Staff should not rely on a patient appearing well before applying routine hygiene measures.

A contaminated surface may contribute to transfer when someone touches it and subsequently touches a susceptible site, another person or equipment. Surface contamination is not the same as an infection, and simply finding germs does not establish where an infection came from.

Consider objects used by successive patients or staff: chair arms, check-in screens, pens and suitable reusable care equipment. Responsibility for decontamination should be agreed before use. Clinical equipment needs methods compatible with its manufacturer’s instructions and the practice’s procedures.

For busy areas, look at how use changes during the day. An evening clean may cover routine premises tasks while some items need attention between uses or following contamination. The clinical lead should help define those boundaries; a general cleaner should not improvise device decontamination.

Some infections can spread through respiratory particles released by an infected person. Exposure may involve close contact or particles in the air, depending on the organism and circumstances. Surface cleaning cannot remove all the risks associated with sharing an indoor space.

Practices therefore need arrangements for recognising symptoms, respiratory hygiene, patient placement and ventilation, with additional protective measures where indicated by current guidance. Reception teams should know the local escalation process when a patient reports potentially infectious symptoms.

Cleaning should support those controls. For a suspected infection, the clinical team should determine precautions and communicate any implications for cleaning access or methods.

The table below identifies everyday touchpoints to include in a local assessment. It is a planning aid, not a universal timetable. Frequency and method should reflect use, contamination, surface compatibility and the practice’s approved policy.

Cleaning can move contamination if tools and working methods are poorly managed. A cloth used in a washroom should not then be used at reception. Dirty solution, poorly stored mop heads or an overloaded trolley can also undermine separation between tasks.

Use the site’s agreed equipment separation or colour-coding system, change cloths and solutions as required, and follow a planned sequence. Keep clean supplies separate from used materials. Equipment should be cleaned or processed as appropriate and stored in a condition suitable for its next use.

Clean surfaces can be recontaminated during normal use. Equally, clean hands may become contaminated through contact with an unclean item. This explains why environmental cleaning and hand hygiene need to work together across the patient journey.

NHS standard infection control precautions include hand hygiene and safe management of the care environment. Staff should follow the relevant indications and technique in local policy. Gloves do not replace hand hygiene, and staff need suitable facilities and supplies to follow the procedure consistently.

Begin with clear responsibilities rather than buying a stronger product. Identify touchpoints, specify approved methods and decide who responds when a surface is visibly contaminated between scheduled visits. Agree an escalation contact for incidents requiring clinical advice.

Keep surfaces accessible, address damaged finishes and check that staff can find the current schedule. Review records when tasks are missed and make sure corrective work is completed. Plan cleaning around room availability so required product contact times can be achieved.

Cleaning alone cannot eliminate infection risks. It supports a broader system that includes hand hygiene, respiratory precautions, ventilation and appropriate clinical procedures. No cleaning contract should be treated as a guarantee that infections will not occur.
