Mono
Infectious mononucleosis (also known as mono, the kissing disease, Pfeiffer's disease, and, in British English, glandular fever) is a disease seen most commonly in adolescents and young adults, characterized by fever, sore throat and fatigue. It is caused by the Epstein-Barr virus (EBV) or the cytomegalovirus (CMV). It is typically transmitted through saliva or blood, often through kissing, or or by sharing a drinking glass, an eating utensil or a needle. The virus is also found in the mucus of the infected person, so it is also easily spread through coughing or sneezing. It is estimated that 95% of adults in the world have been infected with the Epstein-Barr virus at some point in their lives.

Dengue Fever
Dengue and dengue hemorrhagic fever (DHF) are acute febrile diseases, found in the tropics, with a geographical spread similar to malaria. Caused by one of four closely related virus serotypes of the genus Flavivirus, family Flaviviridae, each serotype is sufficiently different that there is no cross-protection and epidemics caused by multiple serotypes (hyperendemicity) can occur. Dengue is transmitted to humans by the mosquito Aedes aegypti (rarely Aedes albopictus).

Epstein Barr
The Epstein-Barr virus (EBV), also called Human herpesvirus 4 (HHV-4), is a virus of the herpes family (which includes Herpes simplex virus and Cytomegalovirus), and one of the most common viruses in humans. Most people become infected at one point with EBV, which is often harmless. It is named after M.A. Epstein and Y.M. Barr, who, along with B.G. Achong, discovered the virus in 1964.

West Nile Virus
West Nile virus is a newly emergent virus of the family Flaviviridae, found in both tropical and temperate regions. It mainly infects birds, but is also the cause of a number of conditions in humans, horses, and some other mammals. It is transmitted by bites of infected mosquitoes.

Shingles
Herpes zoster, colloquially known as shingles, is the reactivation of varicella zoster virus, leading to a crop of painful blisters over the area of a dermatome. It occurs very rarely in children and adults, but its incidence is high in the elderly, as well as in any age group of immunocompromised patients. Treatment is generally with acyclovir. Many develop a painful condition termed postherpetic neuralgia.

Chicken Pox
Chicken pox, also spelled chickenpox, is a common childhood disease caused by the varicella-zoster virus (VZV), also known as human herpes virus 3 (HHV-3), one of the eight herpesviruses known to affect humans. It is characterized by a fever followed by itchy raw pox or open sores.

Smallpox
Smallpox (also known by the Latin names Variola or Variola vera) is a highly contagious disease unique to humans. It is caused by two virus variants called Variola major and Variola minor. V. major is the more deadly form, with a typical mortality of 20-40 percent of those infected. The other type, V. minor, only kills 1% of its victims. Many survivors are left blind in one or both eyes from corneal ulcerations, and persistent skin scarring - pockmarks - is nearly universal. Smallpox was responsible for an estimated 300-500 million deaths in the 20th century. As recently as 1967, The World Health Organization (WHO) estimated that 15 million people contracted the disease and that two million died in that year.
