This article discusses a believed epidemic in Brazil currently, the pathogen, Zika, has been known to scientists for more then 70 years but for some reason has broken out in South America. The pathogen generally presents with mild symptoms in the general population however much like how antibodies can be transferred from mother to child so can many things. Inluding, unfortunately, Zika which in organisms which have an underdeveloped immune system is quite harmful. In infants this means the children are generally born witha condition called microcephaly in which the skull is smaller and results in an underdeveloped brain. Brazil has experienced over 1500% more cases of microcephaly this year when compared to last year. Although only about 1% of infants die due to microcephaly they require life long medical attention and will have learning difficulties and neurological illnesses. It is being spread by mosquitos throughout the country despite the governments best attempts to educate the population and encourage the use of nets and insect repellant. The virus is lytic as it is virulent extremely quickly.
