14. Summary
1. Dried blood samples on filter paper are easy to collect, transport and store.
2. Results equivalent to those from the alternative testing method in serum.
3. An excellent solution for areas with no structure or with precarious laboratory
structure.
4. Studies by Brazilian institutions show that, contrary to the syringe collection
method, dried blood samples on filter paper maintain their properties under
extreme temperature conditions such as 51oC, even when combined with high
humidity.

• Normative instruction SVS/MS No. 151, October 14, 2009
• Official Gazette October 16, 2009
• LIST OF REASONS
• ...“Brazil is going to update the standards for performing anti-HIV tests. The purpose is to
include the most modern methods to increase the options for performing the exams at
laboratories from the public and private systems in Brazil.”
• The main change proposed by the STD/AIDS Department is meant to make testing to
diagnosis HIV in the laboratory quicker.
• The new document could also open the way for the first time for doing tests with dried blood,
using the filter paper collection. The main advantage of the method is the ability to store
blood samples for up to 12 weeks without refrigeration. This methodology, due to its
easiness, doesn’t need specialized collection and transport, and, consequently, lowers the
cost of exams. Another advantage is that the method allows for sending material by mail,
taking the diagnostic method from the urban centers to more distant locations where there is
no available laboratory capacity. Technically, the dried blood samples are not considered
biologically infectious, which facilitates handling and transportation.

17. The Importance of Prevention
“HIV infection in the pediatric population is
a growing problem, mainly in developing
countries hit by the AIDS epidemic.
The most frequent means for children to
become HIV-positive is through their
mothers, during pregnancy, labor or
breastfeeding.

18. The Importance of Prevention
In the 21st century, the perinatal HIV epidemic
remains out of control in many countries of the
world. The Joint Program of the United Nations for
HIV/AIDS (UNAIDS) estimates that 40 million people
are living with HIV/AIDS, 5 million people are
infected every year, of whom nearly 3 million are
children; of these, 500,000 die as a result of infection
and 700,000 will acquire new infections in that year,
and many of them will be dead before reaching
adolescence.

19. The Importance of Prevention
Whatever the disease, it is always better to identify it in the pre-
symptomatic phase or in its early stages. This is the reason why
programs that aim at prevention and early diagnosis of various
pathologies are the main objective of current health initiatives. The
main purpose of these educational and prevention initiatives is to
provide all subsidies to publicize the information necessary to
reduce the rates of infection and mortality.
For example, treatment of syphilis, a disease that can cause
blindness or even death in newborns, can be done with a single dose
of benzathine penicillin in primary cases, or up to three doses (one
per week), in cases of latent or secondary syphilis.

20. The Importance of Prevention
These initiatives can be applied to:
• General Screening Programs: For men and women, for
screening of diseases such as AIDS, syphilis, Chagas disease
and hepatitis B and C.
• Prenatal Screening Programs: To detect infectious disease
in women before or during pregnancy.
• Newborn Screening Programs: Screening (heel prick test)
in newborns.

21. The Importance of Prevention
The importance of diagnostic tests to detect infectious diseases has
been widely publicized by the Brazilian government, and various
prevention programs have become mandatory in Brazil, such as the
newborn screening program which is performed on all children born
in the country.
Programs with this scope, given their magnitude, can only be
implemented using filter paper to collect samples.
These programs, as well as the use of filter paper, were the subjects
of reports, such as the two annexed to this presentation, which were
broadcast on the Brazilian TV news program with the largest
audience, with a statement by the Brazilian Minister of Health.

22. AIDS in Brazil
From 1980 to June 2009*, 544,846 AIDS cases were registered in Brazil. During this period,
there were 217,091 deaths due to this disease. Every year, 33,000 to 35,000 new cases of
AIDS are reported. In relation to HIV, the estimate is that there are 630,000 infected
people in the Brazil.
The epidemic grew inland. From 1997 to 2007, the incidence in cities with fewer than
50,000 inhabitants doubled, showing that the epidemic has moved inland. In 1997, the
rate in cities with under 50,000 inhabitants was about eight times less than that reported
for cities with over 500,000 people. In 2007, this ratio dropped to three times.

23. Syphilis
Around 1 million new cases of syphilis are reported every year in Brazil, according to estimates from
the Ministry of Health. After AIDS, the sexually transmitted disease of most concern to doctors is
syphilis, mainly due to the transmission from mother to child.
From 1998 to June of 2009, 55,124 cases of congenital syphilis (transmitted from mother to child)
were reported in those younger than one year of age in Brazil. On average, 5,000 cases are reported
every year. The Ministry of Health estimates, however, that there should be 12,000 reports annually.
Beginning in 2005, cases of syphilis in pregnant women also began to be reported. From the beginning
of notification up to 2008, 19,608 cases of pregnant women with syphilis were reported, with 6,955
just in the last year – the estimate is that around 48,000 pregnant women contract syphilis annually.
From the perspective of public health, the main challenge in fighting syphilis is the vertical
transmission. During pregnancy, the disease can cause miscarriage and death of the fetus. Its
congenital manifestations include deformed bones, deafness, blindness and neurological problems,
among others, for children.

24. The chances of vertical transmission of congenital syphilis can
be eliminated and HIV infection can drop to 1%, if adequate
prevention and treatment measures are adopted.
