Obligately Transmissible Diseases

Obligately transmissible diseases are a group of diseases that are transmitted only through a specific transmission mechanism. These diseases involve the transmission of pathogenic microorganisms from one organism to another through vectors such as insects, birds, animals or humans.

Obligately vector-borne diseases can be caused by various microorganisms, such as viruses, bacteria, fungi or protozoa. They can cause various diseases such as fever, malaria, encephalitis, typhus, Lyme disease and others.

Transmission of obligately vector-borne diseases occurs through contact with a vector, which is the main source of infection. For example, in malaria, the vector is a mosquito that transmits the malaria virus from a sick person to a healthy person.

Treatment of obligately transmissible diseases depends on the specific disease and its causative agent. In some cases, treatment may include the use of antibiotics or other medications. However, the most effective treatment is prevention, which includes the use of vector protection and good hygiene.

It is important to note that obligately vector-borne diseases are a serious problem for human health and society as a whole. They can lead to serious consequences such as disability and even death. Therefore, it is important to take measures to prevent the spread of these diseases and ensure the safety of the population.

What is an obligate vector-borne disease?

**Obligately transmitted or obligate infection** is a form of infectious process in which the pathogen can be transmitted from a patient only through blood, saliva, urine, feces, genital secretions, etc. The substrate for obligate transmission of infection can be both biological fluids of the human body (blood, urine, etc.) and those secreted to it during physiological excretion (feces, vaginal secretions).

*Many infectious diseases such as syphilis, brucellosis, visceral leishmaniasis, rabies and others are transmitted throughout the world through undisinfected meat products.*

> Obligate infections are characterized by a wide range of sources of infection and the possibility of transmission of the pathogen by any biological tissue (in particular, mucous membranes).

With obligate transmission, infection does not necessarily occur after direct contact of the source of infection with a susceptible person. Under the influence of factors that activate species-specific protective mechanisms and allow bacterial cells
