Among humans, influenza viruses are easily spread from person to person through coughing or sneezing; people become infected by inhaling airborne particles containing the virus. Less commonly, people may be infected by touching surfaces or objects with the virus, and subsequently touching their faces.

Similar to the symptoms of the flu or influenza, such as:

• Fever
• Cough
• Headache
• Fatigue
• Muscle or joint pains
• Lack of appetite
• Runny nose
• Sore throat
• Diarrhea, nausea, and vomiting in some cases

Most people will recover with only supportive management (e.g., bed rest, increased fluid intake, good nutritional diet). Patients admitted to hospitals may be given anti-viral medication like oseltamivir, so it is very important for people showing flu-like symptoms to consult a doctor immediately or inform proper health authorities. 

For children under 16 years old with fever and muscle aches, aspirin should not be given, as this may lead to a reaction called Reye's Syndrome; instead, paracetamol is advised.

Observe proper personal hygiene:
• Cover your nose and mouth when coughing or sneezing.
• Wash hands regularly with soap and water at least for 20 seconds or use an alcohol-based hand sanitizer, especially before and after eating, after using the toilet, and as necessary.
• Avoid touching your eyes, nose, or mouth to prevent the spread of the virus.

Boost your body's immunity:
• Sleep at least 8 hours each night.
• Be physically active.
• Manage your stress.
• Drink plenty of fluids.
• Eat nutritious food, especially fruits and vegetables.

Practice social distancing:
• Avoid crowded places.
• Avoid close contact with sick people.
• Stay home if you are sick until you are free from symptoms to prevent the spread of the virus.
