Q

Difference of paramyxoviridae from orthomyxoviridae

A

The peplomer of paramyxoviridae has both neuraminidase and hemagglutinin while in orthomyxoviridae we find neuraminidase and hemagglutinin in separate peplomer.

Q

Demyelinating disorder of the nervous system

A

Guillain-Barre Syndrome

23
Q

This virus produces respiratory tract infections that are similar to RSV

A

Human Metapneumovirus

24
Q

This is often a result of a previous viral infections

A

Guillain-Barré Syndrome

25
Q

What happens to the body of the patient if the person acquired Guillain-Barré syndrome?

A

The hosts immune system destroyed its own nerves or myelin covering of the nerves.

26
Q

Rubella is also known as

A

3 day measles or German measles

27
Q

Rubella is under what family?

A

Togaviridae

28
Q

Mildest form of common exanthem

A

Rubella

29
Q

Most common transmission of rubella virus

A

Respiratory

30
Q

In rubella virus, the infected mother can pass the infection to the fetus. This process is called?

A

Congenital Transmission

31
Q

Incubation period of mumps

A

7-25 days

32
Q

Severe mumps can lead to the what infections?

A

Parotitis, aseptic meningitis, and meningoencephalitis.

33
Q

True or False

All mumps infection is characterized by the inflammation of parotid glands

A

False. Not all mumps infection leads to inflammation of parotid glands

34
Q

Organs that can be affected if patient has mumps

A

Testes, pancreas, ovaries, and the CNS

35
Q

True or False

When a patient gets infected with rubeola and mumps, after infection they acquire lifelong immunity.

A

True

36
Q

Severe rubeola can lead to?

A

Secondary bacterial infection, Giant cell pneumonia, acute encephalitis, and subacute sclerosing panecephalitis.

37
Q

In Nipah virus, what animal is considered as natural reservoirs?

A

Bats

38
Q

Human may be infected by this virus by resulting from contact with infected horses

A

Hendra Virus

39
Q

All cases of Hendra Virus are confined in?

A

North-East coast of Australia

40
Q

This virus can be acquired through pig-to-human or human-to-human contact

A

Nipah Virus

41
Q

Incubation period of rubeola virus

A

9-11 days

42
Q

It is the least performed and least practical viral detection

A

Viral isolation or culture

43
Q

It is the gold standard for detecting viral infection

A

Viral isolation

44
Q

Why is viral isolation not practical?

A

Because of the long turn around time and it needs a highly skilled and trained laboratory personnel

45
Q

This viral detection is currently considered as the best method for case detection

A

Nucleic Acid Amplification

46
Q

It is a test that is highly sensitive and has very high specificity

A

Nucleic acid amplification

47
Q

It is a test that is not reliable for current cases

A

Antibody detection

48
Q

What test is used to check past infections

A

Antibody detection

49
Q

What viral detection is the most expensive?

A

Viral isolation

50
Q

It is a test that most likely to produce false-positive results

A

Nucleic acid amplification

51
Q

This viral detection test is commonly used today but is not as sensitive as nucleic acid detection

A

Antigen Detection

52
Q

This test most likely to produce false negative results

A

Antigen Detection

53
Q

This detects the presence of viral genome but it does not necessarily mean that the patient has infective virus particles

A

Nucleic acid amplification

54
Q

Its progeny matures by budding through the endoplasmic reticulum and golgi

A

Coronaviridae
