Biomaterial: urine

– Abstain from alcohol and medications the day before. – Do not perform local procedures the day before. – Perform a morning toilet with plain water. – For the study, the first portion of morning urine is taken.

Biomaterial: saliva

– It is recommended to take the test on an empty stomach, or 3-4 hours after eating. – You should not chew gum before taking the test. – You should not smoke an hour before taking the test. – You should refrain from drinking alcohol for 24 hours. – You should not wear cosmetics (lipsticks, lip balms) on your lips.

Biomaterial: blood

– For PCR research and PCR genetics, venous blood is donated. – Blood is collected on an empty stomach, after an overnight fast, or 8-12 hours after eating. – On the day of blood donation, a small amount of clean water is allowed. – 6-12 hours before the study, stressful situations should be excluded and physical activity should be limited. – Avoid fatty foods, alcohol, and smoking. – If possible, medication should be excluded. – For infants – allow the maximum possible pause between feedings before donation.

Cytomegalovirus (CMV) is one of the most common viruses in humans. It belongs to the Herpesvirus family and is called human herpesvirus type 5, or HCMV. This infection can cause serious health problems, especially in people with weak immune systems and newborns.

Cytomegalovirus is also known as the “gentle enemy” because many people live with this virus and it can remain in the body throughout life, remaining in the “repositories” of neurons and other cells. Most cytomegalovirus infections are asymptomatic and undetectable to the immune system.

However, for some populations, such as newborns and people with severe immunodeficiency, this virus can be dangerous. The main routes of transmission of cytomegalovirus include vertical transmission from mother to child during pregnancy, contact with saliva, urine, birth canal secretions, and blood.

Symptoms of CMV infection in newborns can be serious. These include birth defects such as blindness, deafness, mental retardation, and other developmental defects. In adults and children with healthy immune systems, CMV infection may be asymptomatic or may be similar to a mild flu.

Various methods are used to diagnose cytomegalovirus infection, including blood tests for the virus and antibodies to it. This allows you to determine whether there is an active infection, as well as assess the state of the patient's immune system.

Treatment for cytomegalovirus infection is usually not needed for immunocompetent individuals, as their immune systems are able to suppress the virus. However, in newborns and immunocompromised patients, antiviral drugs such as ganciclovir or valganciclovir may be prescribed to suppress the virus and reduce the severity of symptoms.

Prevention is an important part of managing CMV infection. In particular, for women of childbearing age who have active infection or are at risk of infection, it is important to follow safety measures during pregnancy and when in contact with newborns. It is also recommended to create hygienic conditions for handling saliva and other body fluids, especially in health care settings.

In summary, cytomegalovirus infection is common among humans and for many it is of no clinical significance. However, for vulnerable groups such as newborns and immunocompromised patients, it can be a serious health threat. Cytomegalovirus infection requires appropriate monitoring, diagnosis and, in some cases, treatment, as well as adherence to preventive measures to prevent transmission of the virus.
