Introduction: background of the covid-19 pandemic The covid-19 pandemic, caused by the SARS-CoV-2 virus (Severe acute respiratory syndrome coronavirus), broke out at the end of 2019 and soon became a global health crisis. The aforementioned pandemic has caused serious changes in all aspects of our lives, from health and economy to social interactions. All this had the effect of "overnight" changing the way of life, business and communication between people. With this text, we want to provide you with all the relevant information about the corona virus to which we have been exposed, in order to continue to protect our health from various types of mutations and strains. Virus SARS-CoV-2 characteristics SARS-CoV-2 belongs to the corona virus family and is characterized by high infectivity. The main characteristics of the virus include: Ability to transmit from person to person via droplet. An incubation period of 2-14 days, during which symptoms may not appear immediately. Ability to cause a wide range of symptoms, including respiratory problems, fever, loss of sense of smell and taste. Symptoms of corona virus Symptoms vary from person to person, and in some people the virus can be completely asymptomatic. The classic symptoms of the corona virus can be divided into two groups: Mild symptoms: Increased body temperature A cough Pain in throat Fatigue Loss of sense of smell and/or taste A headache Muscle and joint pain Weak physical strength More severe symptoms: Difficulty breathing Inflammation of the lungs (pneumonia) A high temperature that does not respond to antipyretics Disturbance of the digestive system Cloudiness or confusion Chest pain Symptoms in children: In children, the symptoms are often mild and similar to those of a cold or flu. However, it is not excluded that complications may occur in children as well, especially in those with weakened immunity and health problems. Risk groups for covid-19 Not all people are equally susceptible to more severe forms of covid-19. There are certain risk groups that are more susceptible to complications, including: Older adults: especially those over 65, are more susceptible to more severe illness and death from covid-19. Older people often have a weakened immune system and a greater number of chronic diseases. People with chronic diseases: such as diabetes, hypertension, obesity and heart disease are at greater risk for severe forms of the corona virus. People with weakened immunity: including patients with transplanted organs or oncological diseases, are more susceptible to serious complications from covid-19. The impact of the corona virus on pregnant women and newborns The covid-19 pandemic brought with it a risk for pregnant women, because they are more sensitive due to changes in the body's immune system during pregnancy. The following items of the impact of the corona virus on pregnant women and newborns are important: Higher risk for serious symptoms - these include breathing difficulties, pneumonia and the need for hospital treatment. Older pregnant women and those with chronic diseases, such as diabetes or hypertension, are particularly susceptible to a higher risk. Increased risk of premature birth - which can lead to complications for the baby. Premature babies are more susceptible to respiratory problems and other health complications. Transmission from mother to child - although there are no records, there is a possibility of transmission of the virus from mother to child during pregnancy or during childbirth. So far, the definitive mechanism of transmission has not been confirmed, but it is important to follow the doctor's instructions in order to reduce the possibility of transmission of the virus. Vaccination and pregnancy - studies have shown that the coronavirus vaccines approved for use by Pfizer-Biontech, Moderna, AstraZeneca and Johnson & Johnson are safe for pregnant women. Vaccination of pregnant women can protect both the mother and the unborn child. Pregnant women should consult with their doctors to make informed decisions about vaccination. Precautions - pregnant women should adhere to strict hygiene practices, wearing masks, maintaining distance and avoiding close contact with persons who are potentially exposed to the virus. Also, regular communication with a doctor about symptoms or potential exposure to the corona virus is essential for quick reaction and protection of mother and baby. The corona virus has a special impact on pregnant women and newborns, with an increased risk for serious symptoms and complications. Proper prevention, vaccination and cooperation with doctors are very important to ensure the health of mother and baby during the pandemic. Pandemic statistics so far The statistics of the covid-19 pandemic are constantly changing as new data is collected. Basic statistical data in Serbia contain useful information about the corona virus and include the following: Total number of registered cases: is the total number of confirmed infections with the SARS-CoV-2 virus. The number of cases is constantly updated. Number of people tested: is the total number of people who have been tested for the corona virus since the beginning of the pandemic. Number of persons tested in the last 7 days: who
