In the context of meningitis, particularly bacterial meningitis caused by Neisseria meningitidis, the presence of petechiae is significant. This bacterium can lead to septicemia, where the bacteria enter the bloodstream and can cause disseminated intravascular coagulation. This condition can result in bleeding under the skin, manifesting as petechiae.

Their presence can prompt urgent medical intervention, as they suggest a possible systemic infection that requires immediate attention.

The other symptoms listed may be associated with a variety of illnesses and conditions, but they do not have the same direct correlation with meningitis as petechiae do. Cough may indicate a respiratory illness, rash could result from numerous dermatological conditions or viral infections, and jaundice generally points to liver dysfunction rather than CNS infections.
