How to Tell Influenza from Meningococcal Infection

How to distinguish between influenza symptoms and meningococcal symptoms?

Seasonal influenza, referred to as "flu", is an acute respiratory disease caused by influenza viruses. Symptoms include fever, cough, sore throat, runny nose, muscle pain, fatigue and headache, but occasionally vomiting and diarrhea may occur. Most people usually recover on their own within 2 to 7 days.

Meningococcal infection is actually caused by Neisseria meningitidis. Like the influenza virus, it is mainly spread through droplets produced by coughs and sneezes or direct contact with respiratory secretions of patients. It especially likes to "live in seclusion" in the nasal cavity of young people and attacks children with low immunity. Therefore, we often hear about outbreaks of meningococcal infections in student dormitories.

The initial symptoms of meningococci are very similar to influenza, such as high fever, severe headache, muscle aches, stiff neck and drowsiness. However, it can worsen quickly and may lead to skin bruising, rash, vomiting, photophobia or confusion. Shock may also occur. If any of the above-mentioned symptoms occur, you should seek medical advice immediately.
