However, if you develop any kind of allergy against vaccines or developed in past, then don’t take the vaccine without consulting your doctor.

What is Typhoid Fever?

Typhoid is a type of fever that appears due to bacterial infection caused by the bacterium “Salmonella Typhi”. It can expand all over the body and affect vital organs in the human body.

When someone gets affected, the bacterium goes into the intestine, and then blood-stream, white blood cells carry it throughout the body. The fever can be fatal if not treated immediately, and it is highly transmissible.

Some people don’t have symptoms, rather they are carriers who become major vectors of this disease in an outbreak and spread in larger quantities. You should get tested if surrounding people are showing the symptoms and feeling sick. Do get your vaccine and stop contributing in the downfall of the human health.

Infected people can pass the bacteria through the excretory processes; stools, and urine. It spreads when someone eats food or drinks water contaminated with feces of an infected human. Unhygienic conditions often let this decease spread quicker. Hence everyone must get typhoid vaccine injection or pills.

Lining infection is also known as Peritonitis. In peritonitis, the peritoneum tissue is effected which covers internal organs like liver, kidney, and bowel. Peritoneum tissue doesn’t have an inbuilt defense system like other organs.

In peritonitis, the infection first goes into blood before other organs, and this can cause multiple organ failure as blood is circulated all over the body. If it is not timely and properly treated, the patient can die eventually.

The most common symptom is sudden stomach pain, which will keep getting worse over time. Peritonitis can only be treated at a hospital with 24/7 care and respective anti-biotics are injected. At the end of the treatment, a surgery closes the intestinal holes.
