Someone needs to draw her. I'm not a drawfriend, but I can offer some ideas.
>Zika virus is spread to people through mosquito bites.
So some mosquito looking wangs, instead of bat wangs? Maybe antennas? I could see messy black hair suiting this as well. You maybe able to get away with putting some flecks of white or another light color in her hair to resemble the pattern seen on a mosquito.
>The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes).
>conjunctivitis
Maybe make her a stoner? Brazil is suffering from drug related issues like much of South America, so it would make sense.
>Brazil has reported nearly 2,000 cases of babies born with microcephaly, or unusually small brains, the World Health Organization (WHO) said this month.
Maybe her sigil can be a brain with the aforementioned mosquito wangs?
>The National Flower of the country Brazil is the Ipê-amarelo or Tecoma chrysostricha.
She can have this flower in her hair as well.
