7 items containing ‘bacterial nests’ that can easily cause respiratory diseases

TV remote control

Bacteria from hands, leftover food and dirt easily accumulate in the crevices of the TV remote. If not cleaned regularly, this item can become a vector for disease transmission between family members.

Computer keyboard

Computer keyboards are often rarely cleaned even though they are used every day. Dirt, dead skin cells, food residue and grease stuck between the keys create a favorable environment for bacteria to multiply and survive for a long time.

Cellular phone

Mobile phones can contain many bacteria and viruses if not cleaned regularly. Due to frequent contact with hands, public surfaces and sometimes being carried into the toilet, microorganisms easily spread to hands, increasing the risk of disease.

Kitchen sponge

Sponges and dish towels are moist and porous, easily retaining food debris, creating a favorable environment for bacteria such as Coliform to grow. If not disinfected or replaced regularly, these items can spread pathogens to dishes, kitchen surfaces and users’ hands, indirectly increasing the risk of infection.

Toothbrush holder

A toothbrush holder placed near the toilet or sink is susceptible to bacteria from splashing water and air. Some bacteria such as E.coli, Staphylococcus can exist on brushes and racks, especially when not completely dried. When used, bacteria can follow the hands or oral cavity into the body, affecting oral and whole body health.

Door handles, light switches

Doorknobs and light switches are surfaces that are touched many times a day but are often poorly cleaned. Bacteria and viruses can stick to surfaces, spread from person to person through hands, and then enter the body through the nose, mouth or eyes.

Handles and surfaces in the refrigerator

Although the handles and surfaces inside the refrigerator look clean, they are susceptible to bacteria from users’ hands, fresh food, and spilled food. If not cleaned regularly, these areas can contain microorganisms such as E.coli and Salmonella, causing food contamination. Bacteria from contaminated food or hands can indirectly enter the body.
