Staphylococcus, or staph, refers to a group of bacteria frequently found on the skin and in the nose of healthy individuals. The most common type, Staphylococcus aureus, causes infection when it enters the body through a cut or break in the skin, resulting in conditions that range from minor skin abscesses to more serious issues. Taking a bath is generally discouraged due to the risk of spreading the bacteria, though safety depends heavily on the specific type and severity of the infection. Any decision regarding bathing or hygiene with an active staph infection must be made in consultation with a medical professional.
Understanding the Risks of Submersion
Submerging an active staph infection in a traditional tub bath presents two primary risks: contamination of the bathwater and the potential for the bacteria to spread across the body. When a draining lesion, such as a boil or abscess, is placed in water, the staph bacteria shed into the surrounding environment. This contaminated water can then act as a vehicle for the bacteria to reach other areas of the body, a process known as autoinoculation.
The bacteria can easily enter minor cuts, abrasions, or mucous membranes, potentially leading to new infection sites. Staph bacteria may also survive on the tub surface after the water is drained, creating a risk of transmission to other household members. Since Staphylococcus aureus can persist on inanimate objects for extended periods, the bathtub becomes a reservoir if not immediately and thoroughly disinfected.
This risk is particularly pronounced if the infection is draining or involves an open wound, as pus from an infected wound is highly infectious. The warm, moist environment of a bath can also encourage bacterial proliferation, making the contamination of the water more significant. Medical guidance usually directs patients to avoid soaking the infected area completely to minimize the spread of bacteria.
The potential for environmental contamination extends beyond the immediate bath, as the contaminated water can also splash onto nearby surfaces. Household environmental contamination is a significant factor in the spread and recurrence of infections, including Methicillin-resistant Staphylococcus aureus (MRSA) strains. The risk of acquiring a new strain or experiencing a recurrent infection increases when the immediate environment is not kept clean.
Safe Hygiene Alternatives During Infection
Showering is the preferred alternative to bathing when managing a staph infection, as it allows water to run off the body without prolonged soaking. The infected area should be covered with a clean, dry, and preferably waterproof dressing before entering the shower. This measure helps prevent water from directly contacting the wound, minimizing the shedding of bacteria into the water stream and protecting the wound from external contaminants.
After showering, the waterproof dressing should be removed, and a fresh, dry bandage should be applied immediately to the infected area. Soiled dressings must be disposed of promptly and carefully, and hands should be washed thoroughly both before and after this process. The goal is to keep the wound clean and dry while minimizing the risk of spreading the bacteria via touch.
A healthcare provider may recommend specific localized soaks or antiseptic washes as part of a decolonization regimen. These may include chlorhexidine-based soaps or dilute bleach baths to reduce the amount of Staphylococcus aureus on the skin. Dilute bleach baths are typically prepared by mixing a small amount, such as one-quarter cup of regular-strength bleach, into a quarter-full bathtub of water, and are only to be used under a doctor’s explicit direction.
If a prescribed medicated wash is used, it is often applied to the body from the neck down, paying particular attention to skin folds where bacteria can hide. These specialized treatments are generally reserved for recurrent infections or as a decolonization strategy, and they should be used exactly as prescribed by the medical team. The patient should rinse thoroughly with clean water after the prescribed contact time to avoid skin irritation.
Preventing Spread in the Home Environment
Controlling the household environment is an important step in preventing the transmission of staph to others and reducing the chance of reinfection. Staph bacteria, including resistant strains, can survive on surfaces, making environmental cleaning a necessary component of infection control. High-touch surfaces in the bathroom, such as the sink, counter, and toilet seat, should be cleaned daily with a household disinfectant that specifies it kills Staphylococcus aureus.
Laundry protocols must be followed for any items that have contacted the infected skin, including towels, bed linens, and clothing. These items should be washed in the hottest water setting possible, and a drying cycle using high heat is also helpful in killing the bacteria. It is best practice to handle soiled laundry away from the body to avoid transferring the bacteria onto clean clothing.
Personal hygiene items must never be shared while an infection is active. This includes towels, washcloths, razors, and deodorant, as these items can easily become contaminated and transfer bacteria from one person to another. Frequent handwashing with soap and water for at least 20 seconds remains the single most effective intervention for disrupting the transmission of staph bacteria.
