What is tetanus?

Tetanus is a serious nervous system disease caused by toxigenic bacteria. Tetanus is an infection caused by bacteria called Clostridium tetani.

The bacteria typically exist in soil, dust, and animal waste, and they enter the body through skin breaks, most frequently cuts or puncture wounds brought on by contaminated things. It frequently causes the neck and jaw muscles to lock, which makes it difficult to open the mouth or swallow.

Tetanus is different from other diseases that can be prevented by vaccination in that it cannot be transmitted from person to person.

Tetanus needs a medical emergency. Aggressive wound care and
antibiotics will be required.

Severe complications from tetanus can be life-threatening. This bacterium produces toxins that affect the brain and nervous system, causing muscle stiffness. The common way for tetanus to
enter the body through pores can be through broken skin, usually an injury, into a person's body.

Tetanus bacteria are more likely to infect certain breaks in the skin such as wounds contaminated with dirt, f***s or saliva, puncture wounds, burns, crush injuries and injuries with dead tissue.

After exposure to tetanus, it can take 3 to 21 days for symptoms to appear. In infants, it may take 3 days to 2 weeks for symptoms to appear.

Have you had diarrhea after eating something raw?

It’s probably a salmonella infection (Salmonellosis). Salmonellosis, a common bacterial condition that affects the gastrointestinal system.

Salmonella also can be found in undercooked meat, poultry, and eggs or egg products or by drinking unpasteurized milk. The sources also can be from eating contaminated food or drinking contaminated water and touching infected animals, their f***s, or their environment.

What happens if you are infected by Salmonella?

Hemophilia is usually an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery.

There are few symptoms of hemophilia:
• Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work.
• Many large or deep bruises.
• Unusual bleeding after vaccinations.
• Pain, swelling or tightness in your joints.
• Blood in your urine or stool.
• Nosebleeds without a known cause.
• In infants, unexplained irritability.

CHOLESTEROL

So, what is cholesterol? What does it do?

Cholesterol is a waxy substance. It’s not inherently “bad.” Your body needs it to build cells and make vitamins and other hormones. But too much cholesterol can pose a problem.

Cholesterol comes from two sources.
-Your liver makes all the cholesterol you need.
-The remainder of the cholesterol in your body comes from foods from animals. For example: meat, poultry and dairy products all contain dietary cholesterol.

Why cholesterol matters?

Cholesterol circulates in the blood. As the amount of cholesterol in your blood increases, so does the risk to your health. High cholesterol contributes to a higher risk of cardiovascular diseases, such as heart disease and stroke. That’s why it’s important to have your cholesterol tested, so you can know your levels.

The two types of cholesterol are:
1. LDL cholesterol, which is bad
2. HDL cholesterol which is good.

Too much of the bad kind, or not enough of the good kind, increases the risk cholesterol will slowly build up in the inner walls of the arteries that feed the heart and brain. Cholesterol can join with other substances to form a thick, hard deposit on the inside of the arteries. This can narrow the arteries and make them less flexible – a condition known as atherosclerosis.

If a blood clot forms and blocks one of these narrowed arteries, a heart attack or stroke can result.

When it comes to cholesterol, remember: check, change and control.

Tahukah anda bagaimana denggi menjangkiti kita?
- dari seekor nyamuk yang mempunyai virus tersebut, ia menggigit kita dan melepaskan air liurnya bersama virus tersebut ke dalam badan kita.

Apa yang berlaku dalam sistem badan kita?
- ia akan bereplikasi dan dilepaskan ke dalam sistem darah kita (proses ini dipanggil viremia). Ada sesetengah dari kita yang akan mendapat jangkitan serius (denggi berdarah).

Dan bagaimana orang lain boleh berjangkit denggi dari kita?
- seekor nyamuk aedes lain akan datang menggigit kita (ada virus denggi dalam badan kita), lalu membawa virus itu kepada orang lain yang digigit kemudiannya.
