Path of the Pathogen
Symptoms of the MEV-1 Virus Observed in Contagion:
The Centers for Disease Control
-US Governmental Agency.
Steps the CDC Takes to Stop a Disease
1. Research of the symptoms
-Headquarters in Atlanta Georgia.
-Founded July 1, 1946.
What the CDC is Involved With
The CDC involves itself in any situation having to do with disease.
The CDC partners with the World Health Organization (WHO) in the
event of a Pandemic.
2. Research of the chain of infection
3. Use of the statistics of the disease and the replication process to formulate a vaccine.
4. Use of media
Portal of Entry
Our First Stop
Portal of Exit
Mode of Transmission
The cyclical pattern of disease spread starts with the infectious agent.
In our case, the virus Mev-1 portrayed in the movie Contagion is the infectious agent.
Any object that has a suitable environment for the infectious agent to survive on is considered the reservoir.
The fruits on one of the trees in a chinese forest were the reservoir.
Timeline of Symptoms
Chain of Infection
The range at which the infectious agent leaves from one host and/or reservoir to the next.
Examples would be blood, breast milk and bodily fluids
The saliva from the initial contractor of the infectious agent (virus) would be the portal of exit because saliva is a bodily fluid.
This is the range at which the infectious agent travels from one host to the next.
In the movie, the bat retrieved the infectious agent through a fruit which. As he flew near a factory where pigs were being raised he dropped the fruit. One of the pigs ate the fruit and was killed to serve that same night. The chef that butchered him did not wash his hand before shaking Anna (firrst contractor of the virus) hand.
Infected millions of people worldwide
Much like an open door, it is the open fields of a host where the infectious agent can enter. Big examples of which infectious agents enter host are through the mouth and nose.
This man was a cleaner at the restaurant where the pathogen first started. He was the third person to contract the virus and is now coughing and sneezing around others. This can cause airborne sickness through the nose.
These are the organisms that are best prone to carrying the infectious agent.
Older adults and children were and still are in real life situations most prone to catch infectious agents because at a young age, your immune system is still building to fight against intruders. At an old age, your immune system is not working as well as it used to and can not function against infectious agents very well.
Viruses with DNA replicate via 2 cycles:
inject their genetic material into the host cell.
The DNA enters the hosts nucleus and uses the cells machinery to form copies of itself. The new virus bodies then burst out of the cell and infect others.
Viruses are non- living organisms that contain a genetic material surrounded by a protein coat called a capsid. Some viruses may contain an envelope surrounding their protein coat obtained from the host cell.
What are viruses?
Steps in controlling a virus and an outbreak
First, local laboratories examine the virus and try to match it with any existing virus. The CDC communicates with the public in clearly acknowledging what's known and what isn't known.
In the beginning of the movie, the disease, MEV-1, spreads at a rate of 15 deaths for 87 cases. This virus is very similar to the Nipah virus, which first broke out in Kampung Sungai Nipah, Malaysia in 1998. It spread at a rate of 105 deaths for every 257 cases. Today, Bangladesh is most affected from this virus as people can get it from consuming infected dates. On average, 2 out of 3 people die from the Nipah virus.
How Vaccines Work
Vaccines contain weakened forms of the disease.
The immune system identifies these viruses also known as antigens.
Live attenuated vaccines
Contain a living, but weakened, form of the germ (organism).
Contain a killed form of the organism.
Contain just the part of the organism that stimulates an immune response (the antigen).
Contain an inactivated bacterial toxin (toxoid).
There are 4 main types of vaccines:
Types of Vaccines
During the H1N1 Pandemic, the cases were reported locally and then to other government health organizations.
Once reported by the WHO, health officials used social media to distribute the information that they analyzed to inform the public.
What the Media Tells Us:
Symptoms of the Virus
Regions Affected by the Virus
Rates of Infection
Ways to Stay Healthy
A two way portal between health officials and society through which information is collected and then distributed.
Society communicates its concerns through social media, such as Facebook, Twitter, and through search engines. Through these websites, health officials are able to track down how many people are being affected by the disease, where the disease is affecting, and what are the symptoms that the infected are experiencing.
The Significance of Social Media during an Outbreak
The inserted DNA remains hybrid in the cell until triggered by a physical or chemical factor. When triggered it then enters the lytic cycle.
In the movie
, characters recorded their symptoms and came up with their own false conclusions about the virus.
Once antigens are identified white blood cells create antibodies, to fight of the antigens.
