Infectious diseases are the conditions when you get sick due to microorganisms. It can be a bacteria, virus, fungus, or protozoa. You can not see them from your naked eyes, but they are visible under a high-resolution microscope.

Infectious diseases can be transmitted from one person to another. However, the route of transmission differs. Like you can get a respiratory tract infection through respiratory tract droplets, but you would not get a urinary tract infection through respiratory tract droplets. 

Moreover, some infections are transmitted through insects from one person to another such as malaria and dengue. You would not get dengue or malaria infection, just by spending time with the patient having it. But you can get it if a mosquito bites the infected person and then bites you. 

Some infections can be prevented with the help of vaccines. And for some, you need to exercise caution. Handwashing frequently and disinfecting things that come from outside can also help in lowering the incidence of infections. For the prevention of respiratory infections, expert advice is to wear a face mask. It can help in lowering the transmission of infection.

What are the Causes of Infectious Diseases?

Infectious diseases are caused by microorganisms, such as bacteria, viruses, fungi, and protozoa, that are invisible to our naked eyes. We even do not get to know when and how they enter our bodies. They can reach our bodies through the openings such as nostrils, eyes, ears, and mouth. Germs can also enter our bodies through cuts, abrasions, and open wounds. Therefore you need to take extreme care of a deep wound as it can enter your body directly through it. 

In diabetic people, it takes more time than healthy people to recover. Along with drugs that help get rid of the infection, they should monitor their blood sugar levels and keep them well under control. 

People who take immunosuppressant medications such as corticosteroids and azathioprine are at more risk of catching infections because their immune systems are weak. In a healthy person, the immune system helps get rid of the infection by getting activated and killing the foreign particles. But people who take immunosuppressants, their immunity may get low. They should avoid going to crowded areas and wear a face mask while going out. 

People who take chemotherapeutic drugs may also have low immunity. If you are at risk of catching infections, you may need to visit the healthcare provider time and again for expert advice. For that, you can consult with an Internal Medicine specialist in Lahore.
