Public health is one of the major concerns of the 21st century. With lots of new viruses and diseases this is understandable. Health care institutes all around the world spend lots of money every year to provide people with vaccines or cures for all the new diseases, but they just seem to pop-up out of nowhere. Even television commercials were made to inform people about the best ways to take care of themselves and others around them.
The best way of doing that is for all to understand the basic ways that a certain virus is spreading and nevertheless the basic hygiene measures. As we all have been taught, it's better to avoid certain things than to have to cure them.
Moreover, it can be said that these days information is available to almost everyone so the "I didn't knew" excuse if not acceptable. The fewest, and to some unimportant, things can help us live healthier. As we come into contact daily with lots of people, lots of places, it is highly recommended that we wash our hands as often as we possibly can. Everyone comes in contact with lots of germs with our hands and it's highly possible that our organism isn't familiar with some of them. It is a useful method to prevent infection. Another method is to use wet wipes or antibacterial gels. Also covering your mouth and nose in case of cough or sneeze are mandatory measures.
Also, another method would be trying to open widows and let some fresh air into your home. Even if it's very cold outside, a dose of fresh air will strengthen your body and it will protect from viruses. Crowded places can also be a mean of spreading a virus as many of them have an oral spreading. It is recommended to avoid crowded places, but in our daily life it is sometimes impossible to do that. We need to be very careful when we choose to treat ourselves. Some diseases can have specific mutation so that the regular pill doesn't have the desired effect. Consulting a doctor is a good idea as he can provide lots of useful information regarding a specific illness.
All in all, it can be said that sometimes it is better to invest a little in prevention measures than to pay lots of money, and not to mention time, in an expensive treatment.
