Picornavirus (enteroviruses, Rhinovirus, Hep A) And Calicivirus

1. In the summer a poor,

Herpes Simplex Virus

Rotavirus

Coxsackievirus A
NA: ssRNA
Transmission: fecal-oral

Enterovirus 71

Coxsackievirus A is the correct answer because it is known to cause herpangina in young children during the summer. It is transmitted via the fecal-oral route. Enterovirus 71 may cause hand, foot, and mouth disease, but does not typically present with herpangina. Herpes Simplex Virus is not associated with this clinical presentation. Rotavirus is primarily known for causing gastrointestinal infections and does not typically present with herpangina or rash.

2. What virus can a 7 yr old child develop aseptic meningitis, myocarditis, and pleuritis after eating at a dirty restaurant?

Coxsackievirus B

aseptic meningitis: Echoviruses serotype serotype 9: 12.7%,30: 9.5%

Rotavirus

Influenza virus

Norovirus

Coxsackievirus B is known to cause various symptoms like aseptic meningitis, myocarditis, and pleuritis. Norovirus, Influenza virus, and Rotavirus are not typically associated with these specific symptoms.

3. What is the condition shown in the photo below? What are the two picornaviruses that cause it? Is it contagious?

Corneal Ulcer; Herpes Simplex Virus and Varicella Zoster Virus; Yes.

Acute Hemorrhagic Conjunctivitis

Coxsackie A and "Enterovirus"

Pink Eye; Rhinovirus and Influenza; No.

Conjunctivitis; Adenovirus and Respiratory Syncytial Virus; No.

Acute Hemorrhagic Conjunctivitis is caused by Coxsackie A and Enterovirus, leading to redness and bleeding in the eye. It is highly contagious, easily spreading through contact with infected persons or contaminated surfaces.

4. In Nigeria/India Pt comes in with Aspetic meningitis, asymmetric acute flaccid paraysis. What does the pt have? Route? Common COD? (What part of the brain is effected to cause this?)

Tuberculous meningitis from contaminated food or water

Paralytic poliomyelitis from infetion or live vaccine recombination

COD: repiratory failure, medulla

Malaria from respiratory droplets

Hepatitis A from mosquito bites

Paralytic poliomyelitis is the correct diagnosis for a patient presenting with aseptic meningitis and asymmetric acute flaccid paralysis. The route of transmission can be through infection or live vaccine recombination. The common cause of death is respiratory failure, often affecting the medulla region of the brain leading to paralysis.

5. #1 cause of GI disease outbreaks is responsible for 70-80% of outbreaks worldwide. Food-borne but can be person to person.

Norovirus

Hepatitis A

Salmonella

E. coli

Norovirus is the leading cause of GI disease outbreaks globally, with its ability to spread easily from person to person and through contaminated food. While Salmonella, E. coli, and Hepatitis A are also well-known causes of foodborne illnesses, they are not as commonly associated with outbreaks on the scale that Norovirus is.
