Is there any method to reduce the risk of infectious diseases?

Good hygiene and immunization are the best ways to reduce the risk of infectious diseases.

There are several effective and proven ways to reduce the risk of infectious diseases. The main method to reduce the risks of being infected and spread the infection is immunization by vaccination. There are also a few simple changes you can adopt in your everyday life to prevent the spread of infectious diseases. Your primary care physician can advise on measures you can take for prevention of infectious diseases.

Practical Tips to Reduce the Risk of Infectious Diseases

In the case of individuals undergoing chemotherapy, or immunosuppressed patients, pregnant women, older people or children extra vigilance is needed.

Wash Your Hands Frequently

Microbes can live on inert surfaces from a few minutes up to longer periods. Disease-causing microbes can be found everywhere including our homes or workplaces. Doctors‘ recommendation is to wash our hands with soap and water vigorously and thoroughly for at least 30 seconds. In the absence of running water, alcohol-based hand gels or disinfectant wipes.

Never Share Personal Items

It's known that Hepatitis B can be transmitted from sharing toothbrushes or razors, so it is never safe to share your personal items. Towels, handkerchiefs, nail clippers can also be sources of infectious agents - viruses, bacteria or fungi.

Act with Common Sense when You Cough or Sneeze

Coughing or sneezing can spread these infectious disease-causing agents through microscopic droplets in the air. It is important to cover your mouth when you sneeze or cough. It is more recommended to cover your mouth with your arm sleeve or a handkerchief rather than with your bare hands.

Kitchen Hygiene and Eating Habits

Microbes thrive on foods, especially on the cooked meals left at room temperature. Foodborne infectious diseases often appear from poor food preparation and eating habits. Keep the countertops in your kitchen clean, use separate cutting boards for raw meats and vegetables, refrigerate your meal within two hours of preparation. Before you eat or cook fruits, vegetables or meat, wash them thoroughly.

Travel Wisely

Infectious diseases are often picked during traveling. While traveling use a safe water source for drinking and brushing your teeth. Use bottled water when you are in destinations where the quality of water is questionable. When you visit destinations with poor hygiene eat cooked food and try to avoid raw vegetables, fruits or wash them thoroughly and peel them. Update all immunizations that are required for your travel destination.

Practice Safe Sex

Most sexually transmitted infectious diseases can be prevented easily by using condoms.


Consult your primary care physician regarding your immunization status. By getting the recommended vaccinations you will protect you and your loved ones.

Make sure that:

  • Your children received the recommended childhood vaccinations.
  • Your adult vaccinations are up to date.
  • When traveling abroad, get the required additional immunizations.
  • Make sure your pets' vaccinations are up to date.
