What is meningococcal carrier state?
Bacteria called Neisseria meningitidis cause meningococcal disease. About 1 in 10 people have these bacteria in the back of their nose and throat without being ill. This is called being ‘a carrier. ‘ Sometimes the bacteria invade the body and cause certain illnesses, which are known as meningococcal disease.
Which types of viral hepatitis have a carrier state?
However, hepatitis B and C disease can have a carrier state or become chronic, leading to life-threatening liver conditions.
What is a carrier of hepatitis referring to?
Hepatitis B carriers are people who have the hepatitis B virus in their blood, even though they don’t feel sick. Between 6% and 10% of those people who’ve been infected with the virus will become carriers and can infect others without knowing it.
Which hepatitis virus has no carrier state?
Hepatitis E is thought to be caused by a 32 nm icosahedral non-enveloped virus in the Calicivirus family. The viral particles may be found in the stool of infected humans aggregated by antibodies during the acute and convalescent phase of infection. This form of hepatitis does not have a carrier state (Figure 3).
How do you get meningococcal disease?
How is meningococcal disease spread? It spreads from person-to-person by coughing or coming into close or lengthy contact with someone who is sick or who carries the bacteria. Contact includes kissing, sharing drinks, or living together.
Is meningococcal the same as meningitis?
Meningitis and meningococcal disease are not the same thing. Neither of these types of meningitis can be called meningococcal disease. There are also non-infectious causes of meningitis, such as traumatic brain or spinal cord injury. Certain immune conditions can also cause it.
Which of the following viral hepatitis infections will lead to chronic carrier states?
Whereas HAV and HBV are the most common causes of acute hepatitis in the United States, HCV is the most common cause of chronic hepatitis.
What is a carrier state in medical terms?
The condition of harboring an infective organism without manifesting symptoms of infection.
What happens if you are a hepatitis B carrier?
These “acute” cases don’t always need treatment. But it can become chronic. If that happens, it can cause scarring of the organ, liver failure, and cancer, and it even can be life-threatening. It’s spread when people come in contact with the blood, open sores, or body fluids of someone who has the hepatitis B virus.
What are the first signs of meningococcal?
Symptoms

Which of the following hepatitis viruses is associated with the highest risk of progression to chronic infection in adults?
Viral Hepatitis It is unclear whether the Hepatitis G virus is pathogenic in humans or not. Hepatitis A, B, C, and D are endemic to the United States with hepatitis A, B, and C viruses causing 90% of acute viral hepatitis in the United States and Hepatitis C being the most common cause of chronic hepatitis.
Which types of hepatitis develop into a chronic form of the disease?
Hepatitis C can range from a mild illness, lasting a few weeks, to a serious, life-long (chronic) infection. Most people who get infected with the hepatitis C virus develop chronic hepatitis C. Hepatitis A can last from a few weeks to several months.
What does it mean to be a carrier of an infection?
As noted earlier, a carrier is a person with inapparent infection who is capable of transmitting the pathogen to others. Asymptomatic or passive or healthy carriers are those who never experience symptoms despite being infected.
What is a carrier status?
Carrier status tests detect genetic variants that can cause inherited conditions. These variants are often found primarily in certain ethnicities. Test Examples. Relevant Ethnicities. Blood Syndrome.
Can hepatitis B carrier live long?
The estimated carrier life expectancy is 71.8 years, as compared to 76.2 years among noncarriers (Figure 5). These results are consistent with other estimates, which indicate that 15% to 40% of HBV carriers die of liver complications.
Can you be a carrier of Hep B and not have it?
People living with chronic hepatitis B can be carriers. Often, carriers do not have symptoms. This means that they may unknowingly transmit the virus to others. However, within the U.S., there is a low rate of hepatitis B infections, which means that there is a small number of carriers.
