Flu (Influenza)

Influenza (Influenza) is an acute viral infectious disease of the respiratory tract caused by influenza viruses. This disease can affect people of all ages, but those most vulnerable to it are older people, young children, pregnant women and people with weakened immune systems.

Transmission of influenza occurs from a sick person to a healthy person through airborne droplets, that is, through coughing, sneezing and talking. Influenza viruses can also be transmitted through contact with objects that contain them. The incubation period of the disease usually lasts 1-4 days, after which the first symptoms of the disease begin to appear in a person.

The first symptoms of the flu include headache, fever, loss of appetite, weakness and general malaise. Often accompanied by symptoms of runny nose, cough and sore throat. The illness usually lasts about a week, but may last longer in some people.

Most people recover from the flu without any problems by staying in bed and taking antiviral medications. However, sometimes complications occur, such as pneumonia, which can be caused by both primary post-influenza viral pneumonia and secondary bacterial pneumonia. Any type of pneumonia can lead to the death of the patient as a result of hemorrhage in the lungs.

The main bacteria that cause the development of secondary infections in humans are bacteria of the species Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus. Appropriate antibiotics are used to treat these infections.

Having had the flu creates immunity in the human body only to a certain strain or one type of virus, so every year it is necessary to re-evaluate influenza vaccines and update their composition in accordance with the most current strains of the virus.

Overall, influenza is a serious illness that can cause death in severe cases. It is important to follow preventative measures such as regular hand washing and flu shots to protect yourself and those around you from this disease.

Influenza is an acute infectious viral disease that affects the human respiratory system. It is a highly contagious disease as influenza viruses can be passed from person to person through coughing and sneezing. The most common symptoms of the flu are headache and fever. The flu can also cause loss of appetite and weakness, and may last about one week. Unfortunately, the flu can cause complications such as pneumonia. Pneumonia is an inflammation of the lungs that can occur due to infections caused by pathogenic bacteria or viruses. Any pneumonia can develop after influenza and can sometimes cause death. The main bacteria that cause secondary infection include streptococci, staphylococci and Haemophilus influenzae. Antibiotics are usually used to suppress these bacteria. A person who has had the flu will not become more resistant to this disease. If he gets the virus again, his immune system will fight it just as if he were a healthy person. You can get the flu at any age, from infancy to old age, but the likelihood of getting the flu is lower in older adults

Influenza is one of the most common and dangerous infectious diseases in the world. It is caused by a virus and is characterized by an acute onset, high fever, headache, weakness, loss of appetite and other symptoms. The virus is transmitted through airborne droplets from coughing, sneezing, or close contact with an infected person.

The flu usually lasts about a week and has an incubation period (the period from infection to symptoms) that can range from one to four days. Flu symptoms can vary depending on the type of virus. This may include headache and body aches, fever, fatigue, runny nose, cough, nausea. Some people may experience confusion, dizziness, or seizures. In rare cases, the flu can cause damage to the lungs, liver, heart or brain, or even death.

Treatment for the flu usually includes bed rest, drinking plenty of fluids, and taking vitamin C and other medications such as fever-reducers. However, antibiotics are also sometimes required if the infection is complicated by a secondary bacterial infection. Sometimes the flu can be accompanied by complications such as pneumonia, which can lead to serious consequences, including death.

The only effective way to prevent influenza is through vaccination, which guarantees protection against certain types of viruses. The vaccine should be given annually and is recommended for people at high risk of complications from influenza, such as pregnant women,
