In interview for REFORMA, Yéssika Moreno, medical director of Pfizer Mexico, resolves the most frequent doubts about rare diseases.
"A disease is defined as rare based on the prevalence of affected patients within a given population. In Mexico, a disease is rare if it affects less than 5 per 10,000 people, "he explains.
According to the specialist, the quantity and variety of these diseases is such that it is not possible to think of a common symptomatology that encompasses them all.
" There are among 6 thousand and 8 thousand rare diseases, of which 72 percent are of genetic origin and 70 percent affect exclusively the pediatric population, "abounds.
" It is estimated that the prevalence of rare diseases in the world population is 3.5 to 5.9 percent, which implies that in Mexico between 4.3 to 7.3 million people are affected at any stage of their life. "
The complexity of these diseases , he explains, means that even in countries with robust health systems, their diagnosis can take between 6 and 8 years.
