Hello Everyone My name is: Dr Vincent Icheku, a senior
Introduction Hello Everyone My name is: Dr Vincent Icheku, a senior lecturer in the School of Health and social care, London South Bank University.

Presentation topic: My presentation focuses on:
“A new report that may provide clue as to why for 70 years there was no documented cases of birth defect in Africa where Zika virus originated”
4
Background You may recall that the World Health Organisation (WHO) on the 1st of February 2016 declares Zika virus a Public Health Emergency of International Concern. WHY?
5
Zika virus outbreak in Brazil in May 2015 resulted:
WHO (2016)reported: Zika virus outbreak in Brazil in May 2015 resulted: More than 1 million cases, With 4,000 suspected cases of microcephaly and 270 confirmed cases linked to the virus.
6
What is Microcephaly? Microcephaly is a rare congenital disease that is linked with incomplete brain development and causes babies to be born with unusually small heads and, in the majority of cases, brain damage(see figure 1 below).

8
WHO (2017) recently reported that:
Zika virus related microcephaly has now been reported in 20 countries. As many as four million people may be infected with the virus Thus poses a global public health threat
9
Microcephaly in Africa
The African nations were recently alarmed by the World Health Organization (WHO) report confirming an outbreak of the Zika virus on the African island chain of Cape Verde, linking it to cases microcephaly (WHO, 2016).
10
East African Link Zika was first discovered in East Africa in 1947 with no known link to brain or birth defect until the WHO reported cases in May 2016. The question, therefore, is: if the Zika virus has been in Africa for 70 years, why wasn’t any association to microcephaly detected before the recent WHO findings?
11
Aim of this presentation
This presentation is focuses on a new report that seem to offer a clue as to why there was no cases of birth defect in Africa where Zika virus originated. The evidence in the report is part of other possible explanations discussed in my recent book, entitled: “Is Zika virus is the definitive culprit in the cases of microcephaly?”
12
Argentine doctors’ new report
A group of doctors in Argentina calling themselves, “Physicians in the Crop-Sprayed” issued a report that challenges the theory that the Zika virus epidemic in Brazil is the cause of the increase cases of microcephaly.
13
State mosquitoes controlled programme
The report argued that Pyri- proxy-fen’s chemical used in a State-controlled programme aimed at eradicating disease- carrying mosquitoes in Brazil is a dangerous poison capable of birth defects.
14
What is Pyri-proxy-fen
Pyri-proxy-fen is a growth inhibitor of mosquito larvae, which alters the development process from larva to adult, thus generating malformations in developing mosquitoes and killing or disabling them.
15
Pyri-proxy-fen may be responsible the birth defects in Brazil
The report claimed that malformations detected in thousands of babies from pregnant women living in areas (North East) where the Brazilian state used the chemical Pyriproxyfen are not a coincidence.
16
State Denial The Brazilian federal government dismissed the report for lacking scientific base. Contrary to the government’s denial, European Centre for Disease Prevention and Control (ECDC), warned that if authorities continue with chemical spraying (see figure 2), it could increase children's risk of brain disorders

In Conclusion The new report on chemical spraying in North East of Brazil where majority cases of Microcephaly were reported challenges the theory that the Zika virus is the main cause of microcephaly. The fact that there is no documented evidence of Zika-linked microcephaly in Africa where Zika virus existed for over 70 years opens up a new debate as to the relationship between Zika virus and microcephaly.
19
recommendation Finally, research studies are recommended to explain the role of pyri-proxy-fen in the cases of birth defect in the North Eastern Brazil.
