When people think about infection prevention, they often picture hospitals: healthcare workers in gloves, disinfected surfaces, and strict handwashing routines. But some of the most important infection prevention happens in much less controlled environments like our homes.
This becomes especially important when someone is recovering from an illness, living with a chronic condition, caring for a newborn, recovering after surgery, or receiving nursing care at home. A home does not need to look like a hospital to be safe, but there are a few basic standards every family should understand.
Start with clean hands
Hand hygiene remains one of the simplest and most effective ways to reduce the spread of infection. The 2025 WHO and UNICEF guidelines specifically address hand hygiene in homes and other community settings.
At home, important times to clean your hands include before preparing food, before eating or feeding someone, after using the toilet or handling faeces, after coughing or sneezing, and whenever your hands are visibly dirty. Soap and water should be the first choice when hands are visibly dirty. When they are not visibly dirty, an alcohol-based hand rub containing at least 60% alcohol can be used.
This matters even more when someone in the household needs assistance with toileting, wound care, feeding, medication, or other personal care. Family members and caregivers should clean their hands before and after providing care, not only when their hands look dirty.
Clean the home without overdoing it
A clean home does not mean every surface needs to be disinfected constantly. Regular cleaning with soap or detergent and water is enough for most household situations. Disinfection becomes more important when someone is sick or when there is a particular risk of infection.
High-touch surfaces such as door handles, taps, light switches, phones, and frequently used bathroom surfaces should receive regular attention, particularly when someone in the home is unwell. Surfaces should generally be cleaned before disinfecting them because dirt and other material can reduce the effectiveness of disinfectants.
And one important safety rule should never be overlooked: never mix bleach with other cleaning products. Some combinations can release dangerous fumes. If bleach or another disinfectant is being used indoors, follow the product instructions and ensure there is adequate ventilation.
Be careful with laundry, waste and bodily fluids
Caring for someone at home can sometimes involve blood, urine, stool, vomit, wound drainage or other body fluids. These should be treated as potentially infectious rather than handled casually.
Anyone providing care should assess the risk of exposure and use appropriate protective equipment, such as gloves, when contact with blood or body fluids is expected. Used gloves do not replace hand hygiene; hands should still be cleaned after removing them. WHO includes hand hygiene, appropriate personal protective equipment, environmental cleaning, laundry, and waste management among standard infection prevention precautions.
Soiled laundry should be handled carefully to avoid shaking contaminants into the air or onto other surfaces. Waste from routine household care should be managed appropriately, while waste contaminated with potentially infectious material may require additional precautions depending on the illness and type of care involved.
Do not forget the air
Infection prevention is not only about surfaces and hands. Some respiratory infections can spread through particles in the air, particularly in crowded indoor spaces with poor ventilation.
Opening windows and doors where practical, using exhaust fans and allowing fresh air into rooms can improve ventilation. This is particularly useful when someone in the household has a respiratory infection or when several people are spending time together indoors.
In a Nigerian home, this also means thinking practically about how the household functions. If a sick person is sharing a room with other family members because of limited space, ventilation becomes even more important. Where possible, reduce unnecessary crowding around the person who is unwell.
Infection prevention is also about knowing when home care is not enough
Good infection prevention can reduce avoidable exposure, but it cannot replace medical assessment when someone is becoming seriously unwell.
A wound that is increasingly painful, swollen or producing unusual discharge, persistent fever, difficulty breathing, worsening weakness or a significant change in a person's condition should not simply be managed by cleaning the house more thoroughly. These may require prompt medical attention.
For families receiving professional care at home, infection prevention should be part of the care process rather than an afterthought. Healthcare professionals should assess risks, practise appropriate hand hygiene, use protective equipment when indicated, and help families understand how to safely continue care between visits.
A safer home does not have to be complicated
Infection prevention at home is mostly about doing the basics consistently: clean hands, clean surfaces, safe handling of body fluids and laundry, good ventilation, and knowing when professional medical help is needed.
For families caring for someone who is recovering or living with a health condition, these small routines can make the home a much safer place to receive care. And when care becomes more complex, having a trained healthcare professional involved can help the family understand what needs to be done, what to watch for, and when a situation has moved beyond what should be managed at home.
At Medic Connect, this is part of what professional home care should provide: clinical care that fits safely into the realities of everyday family life.
