However, these procedures are not totally efficient and they vary from country to country.Most mosquitos on aircraft do not carry malaria. The few that do are relatively inefficient invaders. In addition, further natural protection is offered by constraints of the hosting countrys climate.A list of airports at risk has been proposed. International sanitary regulations require the area of airports and the perimeter of 400 m (1,300 ft) around the airport to be made free of Aedes aegypti and Anopheles mosquitos. However, the application of disinsection varies from country to country. Outlook
Airport malaria is not considered a serious public health problem but has a high fatality rate and poses a local threat. The prognosis is poor with fatality rates ranging from 16.9% to 26% with almost all the reports being of the falciparum type. History
There were reports from as early as 1925 that diseases including cholera, plague, smallpox, typhus, yellow fever and malaria could make their way across countries within short periods of time on aircraft. Based on the International Sanitary Convention for Aerial Navigation (1933) (Hague), which came into force in 1935 to protect communities against diseases liable to be imported by aircraft, air-traffic health control administrations, dealt with by the Office International dHygiène Publique, Paris, were able to impose maximally excepted measures for this purpose, but left their actual application to each country concerned. Information regarding disease surveillance was supplied by "The Health Organization of the League of Nations" and updates were published and circulated regularly. Individual governments drew up their own regulations accordingly.
Together, these findings strongly suggest that language impairments are the result of an underlying neurological defect in an area of the brain related to language. Studies looking at long-term outcomes for individuals with specific language impairments such as expressive language disorder track these individuals from childhood to adulthood. As Whitehouse and his colleagues  suggest, "When childhood language problems persist into adulthood, they can have far reaching consequences in terms of academic, social and vocational outcomes." These researchers found that children diagnosed with an SLI would have persistent problems with language and are more likely to pursue vocational training rather than university, thereby avoiding professions requiring high levels of literacy. A lower socioeconomic status was also noted by adults who were diagnosed with an SLI as a child. Whitehouse  also reported that these adults had more difficulties in establishing friendships, most likely due to a decreased ability to express themselves socially. Current educational interventions for students with an SLI
Specific language impairments are often secondary characteristics of other disorders such as autism spectrum disorder and attention deficit hyperactivity disorder. In these cases, issues with speech and language are often not treated specifically, but rather attention is given to the primary complaint. Due to the high correlation of an SLI with other disorders, it is difficult to tell the difference between "pure SLI" or language impairments due to the presence of another disorder. See also
