Unfortunately, it’s said that between 3,000 to 49,000 people who get the flu are at risk for death caused by this particular health issue or their symptoms. The WHO also notes that pregnant women, children below 59 months (less than 5 years old), elderly people 65 years old and above, the immunocompromised, and people diagnosed with chronic conditions have a higher risk for developing severe flu cases or complications.
-
Viral pneumonia: This is a lung infection wherein the alveoli, or small air sacs in the lungs responsible for key functions, become inflamed. It’s known that some viruses make their way to the upper portion of your respiratory system when you’re sick. However, if they move further down into the lungs and get extremely close to the alveoli, they can trigger infection and inflammation.
Common pneumonia symptoms include cough, chills, and fever. However, medical care is urgently needed should breathing difficulties, chest pains, severe coughing that expels large quantities of mucus, severe chills or sweating, and persistent high-grade fever above 38.9 °C become present.
-
Bronchitis: This occurs when the mucous membranes of the bronchi in your lungs become irritated. The bronchi are responsible for delivering air from the trachea or windpipe to each of your lungs. Common indicators of bronchitis include fatigue, mild fever, cough accompanied by mucus, tightness of the chest, and chills.
-
Sinusitis: It’s known as swelling of the sinuses, wherein the flu virus may spread to the upper airways of the noise. Sinusitis is characterized by lessened sense of smell or taste, nasal congestion, sore throat, postnasal drip, cough, and pain located in the sinuses, upper jaw, and teeth.
-
Otitis media or ear infection: This is inflammation and swelling of the middle ear. Common symptoms include fever, chills, hearing loss, vomiting, ear drainage, or mood changes.
-
Encephalitis: This is a rare condition wherein the flu-causing virus enters brain tissue and triggers inflammation. Encephalitis may lead to the destruction of nerve cells, bleeding in the brain, and brain damage. Some warning signs of encephalitis include vomiting, high-grade fever, severe headaches, drowsiness, and sensitivity to light.
-
Myocarditis: Some studies have linked certain flu strains to myocarditis or inflammation of the heart muscle., Symptoms include headache, joint aches, fever, sore throat, chest pain, fatigue, swelling present in the legs, ankles, or feet, shortness of breath, lightheadedness, and rapid or irregular heartbeats.
-
Myositis: It’s a chronic and progressive inflammation of the muscles, particularly muscles around the neck, shoulders, back, hips, and thighs. While it only affects a small percent of flu patients, particularly children, myositis may cause muscle pain or weakness and difficulties with movement.
These vaccines may help shield the body against influenza viruses responsible for the illness. Flu vaccines are available in multiple types:
- Inactivated: contains a killed or inactivated virus
- Recombinant: contains higher amounts of antigen compared to standard - dose vaccines
- Adjuvanted: contains an ingredient that helps create a stronger immune response and is recommended for adults 65 years old and above
