1. Introduction to Health Sciences HOMEWORK
Dear students because Dr. Jorge Sinclair can’t sent you his presentation of Hanta virus & to
avoid confusion I have decided to sent you a small homework from which we will use has a
backbone when writing your examination questions.
It doesn’t have a grade, yet I consider you should all do it. If you send a copy of it in .pdf I could
check it and review it.
1. What is hanta virus (which microbe (kingdom, family, species etc) (how many species are?
Filogenetics plz!, how many are new continent and how many are old continent?)
2. Search the history of this disease (first out brakes, where, who? They found the virus or
just suspected? Give places, dates, names)
3. Mechanism of transmission (animal, which body fluid, how it infects humans)
4. Does hanta virus diseases are encoded in the CIE 10?? Which code? And what CIE 10 stands
for?
5. Name the 2 mains syndromes hanta virus produce? What HVPS means?
6. Which are the Panamanian species of hanta virus and where they are found? First year
found? Could you search and compare the differences between Panamanian hanta virus
disease vs other places in the world? Mortality is the same, less or greater?
7. Classify this disease has emerging or reemerging? And what do these words mean? Can you
name other emerging or reemerging diseases?

1. What is hanta virus (which microbe (kingdom, family, species etc) (how many species are?
Filogenetics plz!, how many are new continent and how many are old continent?)
Hanta virus is a life-threatening disease spread to humans by rodents.
Family: Bunyaviridae
Genus: Hantavirus
Species: Hantaan virus
Species: 32 are new continent, 10 are old continent

3. 2. Search the history of this disease (first out brakes, where, who? They found the virus or
just suspected? Give places, dates, names)
In the past century, two major outbreaks of disease led to the discovery of hantaviruses in the Old
and New Worlds. The first outbreak occurred during the Korean War (1950 to 1953), wherein more
than 3,000 United Nations troops fell ill with Korean hemorrhagic fever, which is commonly
referred to as hemorrhagic fever with renal syndrome (HFRS). The second outbreak of disease
occurred in the Four Corners region of the United States in 1993 and was initially referred to as
Four Corners disease, which is now called hantavirus pulmonary syndrome (HPS) or hantavirus
cardiopulmonary syndrome (HCPS). These viruses can cause serious diseases in humans and
have reached mortality rates of 12% (HFRS) and 60% (HPS) in some outbreaks.
3. Mechanism of transmission (animal, which body fluid, how it infects humans)
It is transmitted by infected rodents through urine, droppings, or saliva. Humans can contract
the disease when they breathe in aerosolized virus. Rodent control in and around the home
remains the primary strategy for preventing hantavirus infection.
4. Does hanta virus diseases are encoded in the CIE 10?? Which code? And what CIE 10 stands
for?
ICD 10 stands for The International Classification of Diseases, 10th Revision, Clinical Modification
(ICD-10-CM). It contains codes for diseases, signs and symptoms, abnormal findings, complaints,
social circumstances, and external causes of injury or diseases.
Hantavirus is encoded in the ICD 10, its code is B33.4 for cardio pulmonary syndrome and
A98.5 for Hemorrhagic fever with renal syndrome.
5. Name the 2 mains syndromes hanta virus produce? What HVPS means?
The 2 main syndormes are cardio pulmonary syndrome and hemorrhagic fever with renal
syndrome.

4. 6. Which are the Panamanian species of hanta virus and where they are found? First year
found? Could you search and compare the differences between Panamanian hanta virus
disease vs other places in the world? Mortality is the same, less or greater?
The Panamanian species of haunt virus are Choclo and Calabazo, they were found in Los Santos.
7. Classify this disease has emerging or reemerging? And what do these words mean? Can you
name other emerging or reemerging diseases?
This disease is considered to be reemerging. Emerging means to become evident, whereas
reemerge means to become evident once again.The emergence of zoonotic pathogens remains
one of the great unsolved mysteries in biology. In the past century, numerous pathogens have
emerged and reemerged, with an estimated frequency of one new pathogen every 18 months.
Of these new pathogens, the majority have zoonotic origins in wildlife, and many have been
RNA viruses such as the hantaviruses, severe acute respiratory syndrome coronavirus (SARS CoV),
Ebola virus, Nipah virus, Hendra virus, West Nile virus, and, most recently, the 2009 H1N1 swine
flu that initially emerged in Mexic
