How to Prevent Spreading Respiratory Infections

Stop the Spread Before It Starts

You wake up with a scratchy throat, a runny nose, and that heavy feeling that tells you something is coming. Maybe it’s a cold, the flu, or another respiratory infection. Your first thought might be about how to feel better fast — but your second thought should be about the people around you. Respiratory infections spread easily from person to person, and a few simple habits can make a big difference in protecting your family, friends, and community.

Respiratory infections include illnesses like the common cold, influenza, COVID-19, RSV, and others that affect your nose, throat, and lungs. They spread through tiny droplets and particles in the air when an infected person coughs, sneezes, talks, or even breathes. Understanding how they spread is the first step toward stopping them.

Wash Your Hands — Often and the Right Way

Handwashing is one of the most powerful tools you have. When you touch your eyes, nose, or mouth with unwashed hands, germs can enter your body. Washing your hands regularly removes those germs before they have a chance to make you — or someone else — sick.

The Centers for Disease Control and Prevention recommends washing your hands with soap and water for at least 20 seconds. That is about as long as it takes to hum the “Happy Birthday” song twice. Make sure to scrub the backs of your hands, between your fingers, and under your nails. When soap and water are not available, use a hand sanitizer that contains at least 60% alcohol.

Focus on washing your hands at key moments — after blowing your nose, before eating, after being in public spaces, and after touching shared surfaces like doorknobs or shopping carts. These small habits add up to big protection over time.

Cover Coughs and Sneezes

A single sneeze can send thousands of tiny droplets into the air around you. Those droplets can carry viruses and bacteria that may infect others nearby. Covering your cough or sneeze is one of the simplest and most considerate things you can do when you are sick.

The best method is to cough or sneeze into a tissue, then throw the tissue away immediately and wash your hands. If a tissue is not handy, use the inside of your elbow rather than your hands. Coughing or sneezing into your hands spreads germs to everything you touch right after.

Teaching children to cover their coughs and sneezes early helps build a lifelong habit. Kids spread respiratory infections quickly in schools and daycares, so practicing this at home can help protect whole classrooms.

Stay Home When You Are Sick

This one sounds simple, but it can be hard to do. Many people push through illness because of work, school, or family responsibilities. However, going out while you are sick is one of the fastest ways to spread a respiratory infection to others.

You are often most contagious in the early days of an illness, sometimes even before your symptoms feel their worst. Staying home when you first notice symptoms — fever, cough, sore throat, runny nose, or body aches — helps keep germs from reaching other people. Most healthcare guidelines suggest staying home until you have been fever-free for at least 24 hours without the help of fever-reducing medicine.

If you need medical advice but do not feel well enough to leave home, telehealth services like SendClinic make it easy to connect with a licensed provider by phone or video without stepping outside. Getting guidance quickly can help you recover faster and make smarter decisions about when it is safe to return to your normal activities.

Avoid Touching Your Face

People touch their faces more than they realize — research has shown it can happen many times per hour without us noticing. Each time you touch your eyes, nose, or mouth, you give any germs on your hands a direct path into your body.

Breaking this habit takes practice. Try keeping your hands busy with other tasks, or use a reminder like a sticky note near your desk. If you wear glasses, get in the habit of adjusting them from the frame rather than touching near your eyes. Small changes like these can reduce your risk of picking up an infection from contaminated surfaces.

Keeping shared surfaces clean also helps. Regularly wipe down high-touch areas like phones, keyboards, light switches, and countertops with a disinfectant. Viruses can survive on surfaces for varying amounts of time, so keeping your environment clean lowers the risk for everyone in your home or workplace.

Stay Up to Date on Vaccines

Vaccines are one of the most effective ways to prevent certain respiratory infections or reduce how severe they become. Flu vaccines, COVID-19 vaccines, RSV vaccines for eligible individuals, and the pertussis vaccine (found in the Tdap shot) are all designed to protect you and those around you from serious illness.

Vaccines work best when more people in a community get them. This is sometimes called community immunity or herd immunity. When enough people are protected, it becomes harder for a virus to find new hosts and spread widely. This is especially important for protecting people who cannot receive vaccines due to age or health conditions.

Talk to a healthcare provider about which vaccines are right for you based on your age, health history, and risk factors. Staying current on recommended vaccines is a year-round commitment, not just a one-time event.

You Have the Power to Protect Others

Preventing the spread of respiratory infections does not require anything complicated or expensive. Washing your hands, covering your coughs, staying home when you are sick, avoiding touching your face, and keeping up with vaccines are all steps anyone can take. These habits protect not just you, but the people you love and the broader community around you.

If you or someone in your family comes down with symptoms and you want fast, convenient medical guidance, SendClinic offers affordable video and phone visits with licensed providers — no insurance needed, no waiting room required. Taking action early can help you feel better sooner and keep others safe along the way.
