Doctors describe MERS-CoV as a flu-like illness with signs and symptoms of pneumonia. Sufferers of MERS generally develop severe acute respiratory illness with symptoms like cough, fever, difficulty in breathing, chest pain, body ache, sore throat, malaise, headache, diarrhoea, runny nose, pneumonia and kidney failure.

This is untrue. Rhinovirus does not spread through mosquitoes.

Type 1 poliovirus was the common cause of epidemics. It is the most pervasive strain of poliovirus and highly infectious in nature.

Flavivirus is not an enterovirus. It does not colonise the intestines.

Besides intestine, poliovirus also multiplies in the oropharynx.

A person with fever, salivation and vesicular (blister-like) eruptions on the palms, fingers and toes is infected with foot and mouth disease virus.

Yellow fever virus is transmitted through Aedes mosquitoes (Aedes aegypti).

Amantadine can cure influenza. The mechanism of antiviral activity of amantadine involves interference with the viral protein, M2, a proton channel. Resistance to the drug class is a consequence of mutations to the pore-lining residues of the channel, leading to the inability of the sterically bulky adamantane ring that both share in entering in their usual way, into the channel.

Small rodents act as primary host in tick-borne encephalitis virus. It can complicate to paralysis and long-term brain damage.

This is the incorrect pair. Genital herpes is caused by HSV-2 virus.

Hantavirus can induce hemorrhagic fever in humans. Due to this, overall vascular system is impaired.

Respiratory synctial virus is the major cause of bronchiolitis and pneumonia in infants that are less than one year old.

Swelling of lymph nodes below the ear and at the nape of the neck are the characteristic lesions produced by the infection of rubivirus. This virus causes rubella.

This is the correct match. Morbillivirus produces Koplik's spots as a characteristic symptom of measles. Edmonston strain was used to make live measles vaccine. Mumps is characterised by parotitis (painful swelling of parotid gland). Joint pain occurs in chikungunya.

The initial symptoms of Crimean-Congo hemorrhagic fever (CCHF) are mood instability, agitation, mental confusion and throat petechiae, then soon nosebleeds, vomiting and black stools. The liver becomes swollen and painful. Disseminated intravascular coagulation may occur as well as acute kidney failure, shock and sometimes acute respiratory distress syndrome.
