Chronic infections can cause cirrhosis of the liver or liver cancer in later years. Meningitis-Meningitis, often known as spinal meningitis, is an infection of the spinal cord. It is usually the result of a viral or bacterial infection. Bacterial meningitis is more severe than viral meningitis and may cause brain damage, hearing loss, and learning disabilities. Symptoms include severe headache, fever, nausea, vomiting, lethargy, delirium, photophobia, and a stiff neck. Yellow fever-Yellow fever causes an over 30,000 deaths each year, out of over 200,000 cases. The disease has two phases.

Symptoms include visual impairment, rashes, lesions, intense itching, skin depigmentation, and lymphadenitis.
Pneumonia- Pneumonia has many possible causes, but it is usually an infection of the streptococcus or mycoplasma bacteria. These bacteria can live in the human body without causing infection for years, and only surface when another illness has lowered the person's immunity to disease. Streptococcus pneumoniae causes streptococcal pneumonia, the most common kind, which is more severe than mycoplasmal pneumonia. S. pneumoniae is responsible for more than 100,000 hospitalizations for pneumonia annually, as well as many as 6 million cases of otitis media and as well as over 60,000 cases of invasive diseases such as
