OFFICE OF THE CITY MANAGER
NO. LTC # 323-2016 LETTER TO COMMISSION
TO: Mayor Philip Levine and Members of he City Corn fission
FROM: Jimmy L. Morales, City Manager
DATE: August 2, 2016
SUBJECT: ZIKA VIRUS —WHAT YOU NEED T KNOW
In light of recent developments regarding mosquitoes and potential transmittal of the Zika virus, the
City of Miami Beach would like to make the following information available to its constituents in
efforts to stimulate awareness of the Zika virus and the mosquito that is known to be able to carry
the virus. The attached flyer from the Center for Disease Control (CDC) details the life cycle of the
mosquito. We provide this to enlist the assistance of the community to help remove standing water
that has been in place for more than a few days and could lead to breeding of mosquitoes. Based
upon the information from the CDC, it takes approximately 7-10 days for a mosquito egg to
become an adult mosquito. By reducing the population of mosquitoes it could slow the
transmission of the virus.
Common Zika virus symptoms include: fever, rash, joint pain and conjunctivitis (red eyes). Other
symptoms include: muscle pain and headache. Symptoms can last for several days to a week, and
will rarely require hospitalization. However, scientific studies have shown that pregnant women are
most vulnerable to this virus and may potentially cause birth defects if infected.
Miami Beach is continuing its efforts to remove standing water throughout the City with weekly
sweeps and modified operating procedures. Constituents are encouraged to look for and to
remove standing water from their properties as well as to report any water that has been standing
for more than 48 hours via the eGov App or by calling our Public Works Department at 305-673-
7625. Additional information on the Zika virus can be found at: www.cdc.gov/zika.

Eggs
• Adult,female mosquitoes lay eggs on the inner,wet walls
of containers with water,above the waterline. �,
• Eggs stick to container walls like glue.They can survive s look like black di
drying out for up to 8 months.Mosquito eggs can even
survive a winter in the southern United States.
• Mosquitoes only need a small amount of water to lay eggs.
Bowls,cups,fountains,tires, barrels,vases,and any other
container storing water make a great"nursery:'
Larva
• Larvae live in the water.They emerge from mosquito eggs.

Etapas del ciclo de vida de los mosquitos ,
Aedes aegypti y Aedes albopictus
Huevos s
• Los mosquitos hembra adultos depositan sus huevos sobre las paredes internas de recipientes con agua,las cuales estan
humedas,del nivel de agua hacia arriba.
• Los huevos se adhieren a las paredes de los recipientes como si ,tuevas tienen el aspect°de alto
tuvieran pegamento.Pueden sobrevivir sin estar dentro del agua
por un period°de hasta 8 meses.Los huevos de mosquito
pueden incluso sobrevivir un invierno en la zona sur de Estados 641°
Unidos.
• Los mosquitos solo necesitan una pequena cantidad de agua
p ara depositar sus b ue y os.De man era ue los tazones,las tazas,
las fuentes,los neumaticos,los barriles,los floreros y demas
recipientes que contengan agua son una fabulosa"incubadora".
Larva :.
• Las larvas viven en el agua.Salen de los huevos de mosquito.
Este proceso tiene lugar cuando los huevos quedan cubiertos
por agua(de la Iluvia ode un rociador).
• Las larvas pueden verse en el agua.Son sumamente activas,por
lo que a veces se las llama"saltarinas".
,� r
• Las crisalidas viven en el agua.De la crisalida sale el mosquito
adulto,el cual se desplaza volando hacia diversos lugares.
Crisalidas en el agua.
Adulto
• Los mosquitos hembra adultos pican a personas y animales.Los
mosquitos necesitan sangre para poner huevos.
• Despues de alimentarse,los mosquitos hembra buscan entornos
acuosos para depositar sus huevos.
• Los mosquitos Aedes aegypti y Aedes albopictus no vuelan largas
distancias.En toda su vida,un mosquito vuela una distancia 7
equivalente a unas pocas cuadras.
• Los mosquitos Aedes aegypti prefieren vivir cerca de las personas Un mosquito adulto sale de una crisalida.
y picarlas.
• Debido a que los mosquitos Aedes albopictus pican a personas y
animales,pueden vivir cerca de viviendas o en las areas agrestes
cercanas.
• Los mosquitos viven en ambientes internos y al aire fibre.
