How are Infections Transmitted?
Viral infections are caused by tiny organisms that move from person to person. These microscopic organisms are called microbes, and they enter through openings in our bodies, such as our nose, mouth, ears, anus, or genital passages. Insect or animal bites can also transmit diseases when they pierce the protective layer of our skin.  For many common viral infections, your doctor may prescribe Zovirax (acyclovir), Zovirax cream, Valtrex (valacyclovir), or Famvir (famciclovir) to treat your symptoms. Preventing the transmission of viral infections comes down to blocking harmful microbes from entering our bodies.
Practice Good Hygiene
The best way to avoid spreading an infection to others is to prevent getting an infection. Good personal hygiene habits will help defend against pathogens that try to get into your body. You can significantly reduce the transmission of viral infections by:
- Washing your hands well
- Covering up when you cough or sneeze
- Cleaning and bandaging wounds
- Not picking at scabs, blemishes, and pimples
- Not sharing eating utensils
- Not touching napkins, tissues, or handkerchiefs used by others 
Hygienic Food Preparation
Manufacturers, farms, and food companies take steps to handle and supply food safely. But mass production means we don’t always know where our produce comes from or how far it traveled before it lands in our shopping cart. The time our food spends on display means it interacts with millions of germs every day, so hygienic food practices are important for stopping the transmission of infections through food. 
When shopping, you may want to purchase refrigerated or frozen items after picking non-perishable foods to reduce the time between thawing and cooking. This is because frozen microbes can reactivate and multiply once no longer frozen. If the packaging for meat or poultry is torn, don’t choose it. You should also avoid buying food that has passed its listed expiration date.  Once you get home, you’ll want to follow four steps to handle your food:
- Clean: wash surfaces and hands often. A good rule of thumb for handwashing is to use warm water and soap for 20 seconds before and after handling food.
- Separate: avoid cross-contamination between raw meats and other foods. After cutting raw meat, clean countertops, utensils, and cutting boards with hot water and soap. Cover the dish when marinating meat. When thawing frozen meat, try to ensure juices do not drip onto other foods.
- Cook: ensure your meal is cooked at the right temperature. Undercooking meat is a common mistake that allows viruses to transmit.
- Chill: refrigerate leftovers promptly. Food left out at room temperature for more than two hours should be discarded. 
Vaccines can help your body defend against viruses. They are designed to expose you to a safe amount of the weakened virus so that your immune system learns to recognize and attack the infection.  Health care providers recommend that children take their childhood vaccinations, and adults should ensure their vaccinations are up to date. The most common vaccines include vaccines against the flu, meningitis, pneumonia, shingles, measles, mumps, and hepatitis.  Vaccinating your pets against parvovirus, distemper, hepatitis, and rabies can help protect you and your family. 
Sexually Transmitted Diseases
Because close contact is the primary way viruses transmit, infections by sexual transmission are common. The only way to one hundred percent avoid a sexually transmitted infection is not to have sexual contact. If that isn’t feasible, the next best way to avoid sexually transmitted diseases (STDs) is to practice safe sex guidelines. You and your partner can get tested to ensure you are negative for HIV and other STDs. Then, limiting your sexual partners to each other is advised. Any time you have a new sexual partner, make sure they are tested as well. 
Prior to traveling abroad, ask your doctor about immunizations you may need. Some areas have specific insect-borne diseases. For example, mosquitoes in various tropical regions may carry malaria, dengue, yellow fever, or Japanese encephalitis. Be wary about getting shots or tattoos while overseas because needles and syringes in some places are reused. Boiling tap water before drinking and using bottled water to brush your teeth can reduce the risk of infections. 
Ticks and mosquitoes are carriers of many viruses and bacteria. Most mosquitoes don’t carry diseases in northern climates, but some still do. Ticks can transmit Lyme disease and encephalitis. Since bugs are common in the wild, they are usually transported into your home through contact with your pets. Steps you can take to reduce the risk of bug-related infections include:
- Limiting outdoor activity during peak mosquito hours
- Using insect repellants
- Draining standing water to avoid mosquitoes from breeding
- Removing ticks with tweezers and cleaning the area of the tick bite with an antiseptic. 
Because microbes are invisible to the naked eye, viral infections can be difficult to prevent completely. This is why drugs like Zovirax (acyclovir), Zovirax cream, Valtrex (valacyclovir), and Famvir (famciclovir) are available to treat symptoms when infections do occur. The good news is that practicing good hygiene can help you prevent a large portion of potential infections.
