3. Haemophilus Influenza
This bacteria used to be the number one way for children to contract meningitis. It would often wreak havoc on schools, camps, and other areas where there are tight quarters. As with other types of bacteria, this type may cause mild infections such as sinus infections or upper respiratory infections.
They can go away on their own or with medication. If the bacteria is left untreated and the sufferer does not recover, there’s a chance that it can spread to the bloodstream and turn into meningitis. Luckily, there are vaccinations that have been successful at almost eradicating this bacteria, so it is less likely to be contracted.
Those who have not been vaccinated may still contract it but are more likely o contract a more mild strain. The vaccines for this strain is mandatory for most states, and children cannot attend school or daycare if they have not been vaccinated.
