Deadly Viruses

[ed84c]

I was wondering. In our contries where we dont have outbreaks of such Tropical diseases, e.g. Ebola etc. is this because there is NO viruses or like literally one or two, not nearlly enough to cause infection (prosumabley it takes a few million). If you were able to see an individual virus (deadly tropical) how many would you see in a normal day?

We do not have outbreaks of Tropical diseases in North America because it is not a tropical climate.. *lol*

I suppose you mean Florida?

Sanitation is the key and vaccinations.

Most of the viruses, diseases, etc that are prominent in other parts of the world (ie. 3rd world countries) are due to a lack of proper sanitation and vaccination capabilities.

Exactly. These viruses require some sort of vector to be transmitted, ie. mosquitoes or rats. These vectors usually thrive in conditions unsterile to humans. Swamps, fetid water are great breeding grounds for mosquitoes, which carry the viral strains. Unsterile conditions in swampy, tropical regions cause the vectors to thrive, and transmit their viruses to humans, and other animals.

so thats a no then?

[Cyanide]

A "No" pertaining to what exactly?

[PiLoT]

viral spread can be very rapid even from third world countries due to improved transportation...remember sars? so even if we dont currently have major outbreaks going on, it won't be too farfeched if we get an outbreak several days following another one in a location on the other side of the world.

The US is plagued by the flu every year. Although it might not be considered a deadly one, its still a major concern as it causes losses in productivity.

as cyanide mentioned, yes sanitation is very important as well as knowledge. The availability of hospitals allows sick individuals to get checked out right away and thus prevent further spread of disease.

Today, many of the outbreaks are caused by bacteria contaminated water supplies and with very nasty results. idk too much about this topic but supposedly many of these outbreaks can be contained through efficient collaboration between local, state, and national health systems.

 

btw this is an awesome forum

A couple of factors not mentioned: emergent virus and human immunity

 

the pathology of the virus - as a virus emerges the population is highly susceptible (population is not immune to the virus (high virulence) & the virus tends to be more deadly). Isolating individuals who have been in contact with the infected individual or vector is key from stopping it from spreading. This is a difficult task. 1st world country have a false sense of security that their health systems are adequate for this. Emergency services constantly work on improving this task.

 

The virus will over time becomes less deadly (if a virus kills it's host to quickly, it won't infect other hosts - over time the virus serotype that survives will be the less deadly form). The population overtime will develop a little immunity to the virus.

 

Examples of this - SARS - it took time to get the procedures down to stop the pandemic

 

West Nile Virus - making it's way across the US - cities need to reduce mosquito breeding grounds

 

a side not on Ebola - or even Marburg(just in news) - when these outbreaks occur the virus is still pretty deadly - it kills too fast and with a high % that it's hard to transmit that virus - They usually show up after they destroyed a village.

if you were asking why uk/us dont have epidemics of deadly diseases, then the answre is that they do.

 

influenza can mutate into a lethat form - the last time this happened in the uk (1918) something like 22,000,000 people died. i think the last time it happened in the us was 1976 ('76 swine fever?), and there are indicators that the H1N5 influensa currently infecting chickens could mutate into another pathogenic strain of human flu soon, which would probably be more lathal than ebola

 

and of course theres HIV...

Also, so many people live across tropical asia, africa and america, there's going to be mroe people dying because there are more people living.

Basically ur answer is that climatically in certain places bacteria of a certain type do not survive.

Thaere is also the sanitation and cleanliness that prevents the growth of bacteria and the developement of the bacteria. If thation to grow and develop.Your answer is based on löogic.
