If Haemophilus influenzae Type B disease leads to pneumonia, or an inflammation and infection of the lungs, the symptoms are fever, chills, extreme fatigue, cough, and shortness of breath, says the Centers for Disease Control and Prevention. Other symptoms are chest pain when the patient breathes, sweating, headache and muscle pain. Older patients may not have a fever but may actually see their temperature go down.
Haemophilus influenzae can also lead to bacteremia, which is an infection in the blood. The symptoms also include fever, chills, great fatigue and shortness of breath, but they are accompanied by pain in the abdomen, nausea, vomiting, diarrhea and anxiety, states the CDC.The patient may also be confused.
Meningitis can also be caused by Haemophilus influenzae, according to the CDC. This is an inflammation of the meninges, or the membrane that covers the brain and the spinal cord. The symptoms are fever, headache, nausea, vomiting and stiff neck, says the CDC. The patient is photophobic and also confused. A baby with this type of Haemophilus influenzae infection may be lethargic and not able to feed well. Young children may have abnormal reflexes.
Haemophilus influenzae Type B is spread from person to person, says the CDC. A person can get it when an infected person coughs or sneezes around them.
