Patient N.T.T. (73 years old, in Hanoi) after 5 days of hospitalization, his fever had gone away but he was still tired, had to use a ventilator to help him breathe, and was actively treated at the hospital.
This is one of the A flu infections admitted to the hospital in severe condition, after 3 days of fever.
Mr. T. was one of the serious cases, admitted to the hospital in a state of respiratory failure, with the background of COPD (chronic obstructive pulmonary disease). The flu worsened, causing him to be hospitalized for COPD.
The treating doctor said that in the first days of admission, patient T.'s COPD was very severe, starting on the basis of lung influenza. The patient's blood air began to have CO2 stagnation, which is an increase in CO2 in the blood. The patient has been prescribed bronchial dilation drugs and should consider a non-invasive ventilator, said the doctor.

According to experts, CO2 is a waste product of metabolism in the body, transported through blood to the lungs and excreted through breath. Prolonged CO2 in the blood can cause serious complications, including organ dysfunction, metabolic disorders and heart failure.
According to information from leading hospitals in Hanoi, flu infections, including influenza A cases, have increased in recent weeks, many of which are children and adults, with dangerous complications.
An infectious disease specialist is concerned that the number of influenza A cases is currently higher than that of patients in the same period in 2024; and is likely to continue to increase in the coming time, due to the weather this year with heavy rain, some cases of humid dames appearing early, which are favorable conditions for the influenza virus to develop and spread in the community.
Doctors at a leading infectious hospital in Hanoi note that although many people are infected and self-treated, influenza A is not benign. Chest pain, purple, shortness of breath, sudden fatigue... are signs of dangerous symptoms caused by influenza A.
According to MSc. Dr. Le Thanh Khoi - Head of the Medical Council of the Long Chau Pharmacy and Vaccination Center, the flu causes more severe symptoms than the common cold and can lead to serious complications such as pneumonia.
The most fearsome and common complication is severe pneumonia caused by influenza A infection. The influenza virus attacks directly the lungs, causing joint damage and reduced gas exchange. The patient had a lot of coughing, shortness of breath, chest pain, cyanosis, rapid breathing and could have respiratory failure in a very short time.

Previously, due to limited resources, vaccination was often prioritized only for young children, with the desire to prevent infectious diseases from breaking out in young people. Currently, lifelong vaccination is a common trend, helping to protect the health of all ages, helping to protect the whole, preventing epidemics from breaking out in the community.
According to Dr. Khoi, to protect personal health, especially for high-risk groups such as children, the elderly, pregnant women and people with underlying diseases, proactively getting vaccinated against influenza is very important and should be done as soon as possible.
