Winter - Spring is a special time for respiratory and digestive diseases. Cold, humid and damp weather creates a favorable environment for bacteria and viruses to grow, leading to diseases such as flu, respiratory infections, pneumonia, measles, chickenpox and many other infectious diseases.
In addition, polluted air, dust and smoke from daily activities, traffic and coal burning in the cold season are also factors that reduce the body's resistance, making people susceptible to respiratory diseases such as pneumonia, asthma, acute bronchitis, or allergies.
Furthermore, this is also the festive season, when many people gather in large crowds, creating conditions for the spread of respiratory diseases, especially in cold and poorly ventilated environments.
According to the latest report, Vietnam has recorded several deaths due to influenza A/H1N1pdm in Binh Dinh province. The Ministry of Health has directed medical facilities to strengthen infection control measures, proactively monitor and promptly intervene to prevent deaths. In addition, one case of influenza A(H9N2) infection in humans has been recorded.
This case occurred in an adult with underlying medical conditions who required hospitalization and monitoring. In addition, H5N1 avian influenza has also appeared in Khanh Hoa province, with a 21-year-old male student dying from the infection.
According to a representative of the Safpo/Potec vaccination system, the current flu vaccination rate among people has not fluctuated much, which shows that people are still quite subjective about this disease.
People who have been vaccinated against influenza have a 26% lower risk of being admitted to the intensive care unit (ICU) and a 31% lower risk of dying from influenza than those who have not been vaccinated, according to a representative of the Safpo/Potec vaccination system.
In the elderly and those with underlying medical conditions, the vaccine can reduce influenza-related deaths by 70-80%. In particular, the flu vaccine also helps pregnant women reduce the risk of stillbirth by 51% and reduce the risk of hospitalization for infants under 6 months of age by 72%.
Currently, Vietnam has two new generation quadrivalent influenza vaccines, which prevent four common influenza virus strains: influenza A/H1N1, A/H3N2, B/Yamagata and B/Victoria, for both children from 6 months old and adults. This vaccine is up to 90% effective in preventing the disease, while also helping to prevent complications such as otitis media, sinusitis, pneumonia, myocarditis and respiratory failure.
According to medical experts, seasonal flu is an infectious disease that can spread quickly, especially during the cold season. The disease is caused by the influenza virus (Influenza virus) of the Orthomyxoviridae family, with two common groups: influenza A (accounting for about 75% of cases) and influenza B (accounting for about 25%).
Flu viruses are easily transmitted from person to person through coughing, sneezing, or contact with contaminated surfaces. Getting vaccinated can help reduce your risk of getting the flu and protect you from exposure to large crowds at events.
Flu symptoms typically include fever, headache, muscle aches, fatigue, runny nose, sore throat, and cough, and usually resolve within 2 to 7 days. However, the illness can become severe and lead to death if the virus invades the organs, causing pneumonia, myocarditis, encephalitis, or sepsis.
People at risk of severe complications from the flu include people aged 65 and over, pregnant women, young children, and people with underlying medical conditions such as heart disease, asthma, chronic obstructive pulmonary disease, kidney failure, and diabetes. One of the most dangerous complications of the flu is pneumonia.
Influenza is an acute respiratory infection caused by influenza virus, which can spread rapidly through droplets when coughing, sneezing or contact with virus-infected surfaces.
Although flu is usually mild and self-limiting in healthy people, for those with weakened immune systems, flu can lead to serious complications such as pneumonia, respiratory failure, or even death.
In addition, flu can also increase the risk of other diseases such as otitis media, sinusitis or worsen underlying diseases such as cardiovascular disease and diabetes.
