Mosquitoes And Mosquito Bites: A Permanent Problem?
Without doubt only the most dedicated of entomologists and the most fervent followers of Buddha can honestly say that they like mosquitoes. The others of us in the world loathe them. The word 'mosquito' comes from either the Spanish or the Portuguese and means 'little fly'. They live in most countries throughout the world and are or have been to blame for spreading various diseases throughout history.
Malaria is the sickness most usually connected with mosquitoes and at one time malaria was widespread in Europe. Even London was a malarial city until they drained the marshes to create space for more housing a couple of hundred years ago. Until a hundred years ago, malaria was not thought to be associated with mosquitoes, it was considered to be brought on by 'bad air' ('mal aria').
Mosquitoes are blood-sucking insects, or at least the females are, that are still to blame for spreading many diseases throughout the animal kingdom. That is correct! They do not just affect humans. Dogs in particular get a fairly hard time from mosquitoes.
For a large part of their lives, mosquitoes happily drink nectar from flowers like bees do, but while the female is pregnant, she needs animal protein to produce eggs. This is what she obtains from us and other animals. The male never has to drink blood.
It is when the female is drawing a little blood, that an infected mosquito involuntarily deposits a couple of parasites into the host's blood stream, which could cause infection with malaria, dengue, encephalitis or numerous other diseases that are spread by parasites.
Not all bites from infected mosquitoes bring about sickness. In the case of malaria for example, it has been contended that a healthy person can fight off the parasites injected by up to fifty mosquitoes in a twenty-four hour period. After that though, the parasites grow in number too quickly for our defences and get to the organs that they like to colonize.
When a non-infected mosquito sucks blood from an infected human, that mosquito can pass the parasites on to other non-infected humans. It is thought that most mosquito bites happen indoors when the person is sleeping. Therefore, the WHO and other agencies have been distributing mosquito nets treated with insecticide in Africa, where most victims of mosquito borne infections reside.
However, there is a concern that treating the problem in this manner might make some sorts of mosquito immune to the insecticide or might even raise the chances of being bitten outdoors. There have been comparable concerns in Cambodia. Until recently, it took three days of hospitalization to cure a patient of malaria, but in one area of Cambodia it now takes five days.
Doctors treating patients in that area say that this is a very disturbing development. It is thought that if this local development spreads, then it could result in the deaths of millions of Africans again.
Most mosquitoes do not fly far. Most mosquitoes never go over two kilometres from where they hatched out; some move only a couple of metres away, although others can fly some 5 or 10 kilometres, and a very few species will even fly up to 50 kilometres, assisted by the wind, from their pupal locations.
