Transmission means the way germs move from one person, animal, or surface to another. Simple changes in how you behave and care for your environment cut transmission a lot. This page gives clear, usable steps you can use at home, work, and in healthcare settings.
There are a few common routes: direct contact (touching an infected person), droplets (coughs and sneezes), airborne (tiny particles that float), fomites (contaminated surfaces), vectors (bugs like mosquitoes), sexual contact, and vertical (mother to baby). Some infections use more than one route. For example, Candida can spread from devices like catheters into the bloodstream in hospitals — that’s covered in our article "Catheters and Candida: Exploring Device-Linked Candidemia and Systemic Fungal Risks."
Knowing the route helps you pick the right prevention. Handwashing won’t stop mosquito bites, and bed-netting won’t block airborne particles. Match the measure to the risk.
Wash your hands with soap and water for 20 seconds or use an alcohol hand rub when soap isn’t handy. Do it before eating, after using the bathroom, and after being in public spaces. Don’t rush this — proper technique matters.
Cover coughs and sneezes with a tissue or your elbow. If you’re sick, stay home when possible and wear a mask in crowded or poorly ventilated places. Masks reduce droplet spread and help when airborne risk is present.
Improve indoor air: open windows, use exhaust fans, or add air purifiers with HEPA filters in rooms where people gather. Good ventilation lowers the concentration of airborne germs.
Clean and disinfect high-touch surfaces regularly — doorknobs, phones, keyboards. For shared items in schools or offices, a quick wipe-down with an appropriate disinfectant makes a big difference.
Practice safer sex and get tested if you think you’ve been exposed. For bloodborne viruses like hepatitis C, avoid sharing needles or personal items that can carry blood. We explain hepatitis C risks and liver effects in "Understanding the Connection Between Hepatitis C and Liver Disease."
In healthcare settings, ask questions: Are catheters really needed? Is the staff following sterile technique? Device-related infections are preventable with proper care and timely removal.
Use antibiotics only when prescribed and follow the full course. Misuse fuels resistant germs, making infections harder to stop. Read our guides on antibiotic choices and alternatives for practical context.
Vaccines are among the most effective tools to stop transmission for many diseases. If a vaccine exists for a threat in your community, getting it protects you and people around you.

Small, consistent actions add up. Hand hygiene, masks when needed, good ventilation, safe medical care, and smart medication use are practical steps anyone can take to cut transmission now.
