In the first 4 months of this year, Hai Duong Children's Hospital recorded a higher number of children with influenza B than the same period last year. The symptoms of influenza B and influenza A are basically the same and cause significant impacts on the health of patients.
* Symptom
Influenza A and influenza B can both be equally severe, with common symptoms including fever, chills, sore throat, cough, runny nose, sneezing, fatigue, and body aches.
Similar to the common cold, influenza B can cause respiratory symptoms. Initial symptoms often include cough, congestion, sore throat, and runny nose.
However, respiratory symptoms caused by influenza can be more severe and lead to other health complications. If you have asthma, respiratory infections can worsen your symptoms and even cause a severe asthma attack. If left untreated or in more severe cases, influenza B can cause pneumonia, bronchitis, respiratory failure, kidney failure, myocarditis or heart inflammation, blood infection, etc.
In rare cases, influenza B can also cause diarrhea or stomach pain. These symptoms are common in children and can easily be mistaken for stomach problems. Children infected with influenza B may also experience nausea, vomiting, abdominal pain, and loss of appetite.
* Treatment of influenza B
If you suspect you have the flu, you should drink plenty of fluids to avoid dehydration. You should also get plenty of sleep to help your body rest and recharge.
Sometimes flu B symptoms will go away on their own. However, people who are at high risk of complications from the flu should see a doctor immediately for prompt treatment.
People at high risk of complications include children under 5 years old, especially those under 2 years old; the elderly aged 65 years and older; pregnant women or women who have given birth less than 2 weeks ago; people with weakened immune systems or certain chronic diseases.
For children with the flu, parents should prioritize taking their children to a medical facility before applying home remedies. Some medications, if used indiscriminately, can increase the risk of complications. Children with a fever due to the flu should stay home for at least 24 hours after the fever subsides naturally (without medication). In some cases of flu, doctors will prescribe pain relievers and antiviral drugs to shorten the duration of the illness and prevent more serious complications from occurring.
Doctors and many health organizations around the world recommend that people get vaccinated against influenza B and other types of flu every year to protect themselves against common strains of the virus.
