According to writer, Drs Robert Schechter and Judith K. Grether from California Departement of Public Health, there is permanent improvement a few latter years in diagnosing trouble cases autis, what covers autis and related condition.
Some groups is maintaining autis because of or triggered by preservative presentation based on mercury in vaccine. Content timerosal approximant 50% etilmerukri based on wt. and applied to kill or prevents growth various pathogens.
In the year 2001, timerosal pulled from most all vaccines in America Utar and Europe. Step by step replaced with material non mercury and some vaccines is formulation so that didn"t require again preserver.
Schechter and Grether cases data analysis autis child of at California Departement od Developmental Service from the year 1995 until March 2007. Finding they as follows :
* For every year age 3-12 years, estimation of prevalence autis child of increasing during study period.
* For child of bearing before 1993, prevalence autis at the age of 3 year is 0,3 / 1000 chlids.
* The year 2003, prevalence autis child of age 3 year is 1,3 per 1000 chlids.
* estimation of Highest prevalence happened the year 2006, that is 4,5 of 1000 chlids borns the year 2000 estimated to suffers autis.
* Although too early to calculate prevalence for age 6 year or more children borne after the year 2000, prevalence at the age of 3-5 years had increased every year since the year 1999.
* Timerosal has pulled at the same period with case autis child of age 3-5 years increases.
* Based on image of quarter, case number autis at the age of 3-5 years increases every quarter from January 1995 ( 0,6 per 1000 life births) up to maret 2007 ( 4,1 per 1000 life births).
Writer concludes that based on their analysis to data Departement of Developmental Service indicates that happened improvement of autis in Kalfornia although timerosal eliminated from all vaccines. They support continuation effort for invention of modification risk factors for autis and related condition.
