Swine flu
Humans are not immune to the swine flu (N1H1) virus. For the treatment or prevention of swine flu, the American Centre for Disease Control and Prevention (CDC) recommends the antiviral drugs Oseltamivir or Zanamivir. There are also everyday actions that can help prevent the spreading of germs and viruses:
- The influenza virus is killed by heat or alcohol wipes. Wash your hands and living environment regularly.
- Cover your nose and mouth with a tissue when you cough or sneeze.
- Avoid touching your eyes, nose and mouth, as this is the easiest way for germs to spread.
- Avoid close contact with sick people.
- Stay home for seven days if you're sick, or until you have been symptom-free for 24 hours, to prevent others from contracting the virus.

Meningitis
Meningitis is an infection of the fluid that surrounds the brain and the fluid of the spinal cord. It is a very dangerous and infectious disease. Meningitis is usually caused by a bacterial or viral infection and the treatment and severity of each differ. If you suspect that you have meningitis, go to hospital immediately. Meningitis caused by a viral infection can be mild and harmless, but there is a chance of complications and a home cure should not be attempted until doctors give you permission. Bacterial meningitis is very dangerous because of the high risk of additional symptoms, such as seizures, prolonged fever and loss of hearing or vision. Treat all new complications immediately to avoid permanent damage. The correct antibiotics will also have to be administrated in order to clear out the infection.

Here are a few warning signs that you may have meningitis:
- An unexplained and rapidly high fever
- A painful headache
- Severe pain in your neck and back
- A rash where spots can be small and red, or large and bruise-like
- Your eyes are suddenly sensitive to light
- Vomiting or fatigue

Tuberculosis
According to the CDC, more than one-third of the world's population carry the tuberculosis bacteria, and a new infection occurs once every second. Tuberculosis attacks the lungs and causes chest pains, causing you to cough up blood and have a phlegm-filled cough that lasts more than three weeks. It also triggers night sweats, appetite loss, weight loss and fatigue. If left untreated, there is a 50% you could die. Treatment involves long periods of antibiotic therapy that lasts from six months to a year.

If you suspect you may have contracted TB:
- Visit your doctor immediately and take the medication prescribed by them.
- Stay at home. TB is highly contagious and you are required by law to stay in isolation while you are infected.
- Take extra vitamin B6, as it helps the liver counteract the negative side-effects of the anti-tuberculosis drugs.
- Eat lots of fruits and vegetables to aid your body's healing process.
- Stay away from smoke or other airborne irritants.
