Diseases Infectious

Infectious diseases, also known as contagious diseases or infectious diseases, are widespread and are caused by various pathogenic microorganisms such as bacteria, viruses, fungi or protozoa. These diseases are transmitted from person to person and through contact with infected animals or the environment.

Infectious diseases can have different symptoms and manifestations, depending on the specific pathogen and the organs that they affect. They can affect various body systems, including the respiratory, digestive, nervous and reproductive systems. Some of the most common infectious diseases include influenza, chickenpox, hepatitis, tuberculosis, AIDS, malaria, pneumonia, cholera and AIDS.

The spread of infectious diseases can occur in various ways. Droplet transmission of pathogens occurs through coughing, sneezing or talking with an infected person. Contact transmission of pathogens includes physical contact with infected surfaces or objects, as well as direct interaction with an infected person. Transmission through air, water or food is also possible.

Prevention and control of infectious diseases are based on several principles. Vaccination is one of the most effective ways to prevent infections. Vaccines help the body develop immunity to certain pathogens, which reduces the risk of disease or makes it milder. Other preventative measures include frequent hand washing with soap, practicing good hygiene, using condoms to protect against sexually transmitted infections, and isolating infected individuals to prevent the spread of disease.

Treatment for infectious diseases depends on their type and severity. Bacterial infections are often treated with antibiotics, which kill or slow the growth of bacteria. However, viral infections cannot be treated with antibiotics, and in such cases, antiviral drugs are used to help control symptoms and strengthen the body's immune system.

Controlling infectious diseases is an important public health challenge. Global organizations such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) play a key role in monitoring, preventing, and treating infectious diseases.

However, despite many advances in medicine and public health, infectious diseases remain a significant problem for the global population. New pathogens and variants of existing diseases continue to emerge, and some infections are becoming drug-resistant. This highlights the need for ongoing research, development of new diagnostic and treatment methods, and increased public awareness of infection prevention and protection.

Ultimately, the fight against infectious diseases requires the collaborative efforts of all parties: governments, medical organizations, the scientific community and the public. Striving for the development of effective vaccines, improved hygiene conditions, access to antibiotics and antivirals, and education and awareness of infection prevention must remain a priority to ensure the health and well-being of our planet.

In conclusion, infectious diseases pose a serious threat to public health. But thanks to scientific and medical advances, as well as preventive measures, we can reduce the spread and impact of these diseases. By continuing research and collaboration, we can strive for a healthier future, free from the burden of infectious diseases.



Infectious diseases (morbi infectious) are diseases that arise as a result of the action of pathogenic agents (bacteria, viruses, parasites, fungi) on the human body. Infection is the introduction of bacteria or viruses into the human body through damaged or unprotected skin or mucous membranes.

There are many infectious diseases, but they all have common symptoms and causes. The most well-known infectious diseases are influenza, measles, rubella, whooping cough, chicken pox, tuberculosis, HIV infection and others. During illness, a change in the internal environment of the body occurs under the influence of a pathogenic agent.

Examples of infectious diseases are: Influenza is the most common viral infection. The first symptoms are high fever, chills, headache, cough and general weakness. Treatment of the disease is symptomatic, often requiring antiviral drugs or antibiotics. Measles - manifests itself as a high temperature, runny nose, sore throat, headache, cough and a red spot on the conjunctiva of the eye. Treatment is antiviral and symptomatic. Rubella - causes general weakness, fever, sore throat, and malaise. The disease is transmitted by airborne droplets, treat it with symptoms
