WHAT YOU NEED TO KNOW ABOUT ZIKA
WHAT IS ZIKA?
The Zika (ZEE’-ka) virus was first discovered in monkey in Uganda in 1947 – its name comes from the Zika forest where it was first discovered.
It is native mainly to tropical Africa, with outbreaks in Southeast Asia and the Pacific Islands.
It appeared in Brazil in 2014 and has since been reported in many Latin American countries and Caribbean islands.
HOW IS IT SPREAD?
It is typically transmitted through bites from the same kind of mosquitoes – Aedes aegypti – that can spread other tropical diseases, like dengue fever, chikungunya and yellow fever.
It is not known to spread from person to person.
Though rare, scientists have found Zika can be transmitted sexually. The World Health Organisation recently warned the mode of transmission is ‘more common than previously assumed’.
And, the Centers for Disease Control and Prevention recently issued first-time guidance, saying couples trying to conceive should abstain or wear condoms for six months if the male has confirmed or suspected Zika.

Additionally, the CDC said couples should abstain or wear condoms for eight weeks if the female has confirmed or suspected Zika, or if the male traveled to a country with a Zika outbreak but has no symptoms.
During the current outbreak, the first case of sexually transmitted Zika was reported in Texas, at the beginning of February.
The patient became infected after sexual contact with a partner diagnosed with the virus after travelling to an affected region.
Now, health officials in the US are investigating more than a dozen possible cases of Zika in people thought to be infected during sex.
There are also reported cases in France and Canada.
Prior to this outbreak, scientists reported examples of sexual transmission of Zika in 2008.
A researcher from Colorado, who caught the virus overseas, is thought to have infected his wife, on returning home.
And records show the virus was found in the semen of a man in Tahiti.
So far, each case of sexual transmission of Zika involves transmission from an infected man to his partner. There is no current evidence that women can pass on the virus through sexual contact.
The World Health Organization says Zika is rapidly spreading in the Americas because it is new to the region, people aren’t immune to it, and the Aedes aegypti mosquito that carries it is just about everywhere – including along the southern United States.
Canada and Chile are the only places without this mosquito.
ARE THERE SYMPTOMS?
The majority of people infected with Zika virus will not experience symptoms.
Those that do, usually develop mild symptoms – fever, rash, joint pain, and red eyes – which usually last no more than a week.
There is no specific treatment for the virus and there is currently no vaccine to protect against infection, though several are in the developmental stages.
WHY IS IT A CONCERN NOW?
In Brazil, there has been mounting evidence linking Zika infection in pregnant women to a rare birth defect called microcephaly, in which a newborn’s head is smaller than normal and the brain may not have developed properly.
Brazilian health officials last October noticed a spike in cases of microcephaly in tandem with the Zika outbreak.
The country said it has confirmed more than 860 cases of microcephaly – and that it considers them to be related to Zika infections in the mother.
Brazil is also investigating more than 4,200 additional suspected cases of microcephaly.
However, Brazilian health officials said they had ruled out 1,471 suspected cases in the week ending March 19.
Although Zika has not been conclusively proven to cause microcephaly, the World Health Organization has said that there is a ‘strong scientific consensus’ that it does.
The WHO also stated that researchers are now convinced that Zika is responsible for increased reports of a nerve condition called Guillain-Barre that can cause paralysis.
A team of Purdue University scientists recently revealed a molecular map of the Zika virus, which shows important structural features that may help scientists craft the first treatments to tackle the disease.
The map details vital differences on a key protein that may explain why Zika attacks nerve cells – while other viruses in the same family, such as dengue, Yellow Fever and West Nile, do not.
CAN THE SPREAD BE STOPPED?
Individuals can protect themselves from mosquito bites by using insect repellents, and wearing long sleeves and long pants – especially during daylight, when the mosquitoes tend to be most active, health officials say.
Eliminating breeding spots and controlling mosquito populations can help prevent the spread of the virus.
One of the best known summer pests, mosquitoes breed in stagnant water or soft soil and can develop from egg to adult in 10 to 14 days. Squads of Mosquito from a variety of water sources and hidden under small bushes invade your environment causing these pest to ruin your family time and parties.
Typically, a female mosquito seeking a blood meal will detect a host from a distance (120 ft. or more) downwind, fly up the odor plume, and land nearby but not on the host. After a brief rest, she will fly the short distance to the host, land, and feed. After she has taken her fill, she will fly a short distance away (usually less than 10 ft.) and rest on a vertical surface for more than an hour while she eliminates about half of the water from that blood meal before she flies off to a typical breeding site, to finish developing and laying her eggs.
This is done by almost every species of human-biting mosquitoes.
Mosquitoes have four stages: Eggs, Larvae, Pupae, and Adults.
Eggs are laid in or near water. Not all mosquitoes lay eggs on stagnant water. Asian Tiger Mosquitoes and their relatives lay single eggs either in or on moist organic matter (like old leaves) or mud at or near the normal surface of some water body or standing water. House Mosquitoes and their relatives lay their eggs stuck together in “rafts” on the surface of standing water. Malaria Mosquitoes and their relatives lay single eggs directly on the surface of standing water.
Larvae of nearly all species feed on tiny bits of organic matter they strain out of the water, using brushes on their mouths. They usually move by jerking their body, end-for-end, in a sideways whipping motion. Nearly all species must come to the water surface fairly often, where they breathe atmospheric air through a special tube or plate at their back end.
Pupae are a non-feeding, but active stage that must stay in the water to live. They also must breathe air at the water’s surface through special tubes on their backs.
Adults emerge from pupae in the water. If water is not calm enough, they may not emerge normally; and may get stuck or drown. They have to sit on top of the water until their body and wings dry and harden. They fly to nearby plants and feed on nectar or juices, getting energy from the sugars in those. Males need about 24 hours after they emerge before they can mate. After mating, females find vertebrate hosts and take a blood meal which provides protein for their eggs. Each full blood meal usually provides enough protein and energy for the female to produce about 100 eggs.
Adults usually rest on vertical surfaces like tree trunks, twigs, or walls with their head upward.
Female mosquitoes suck our blood. Male mosquitoes feed on plant nectars. They can develop from egg to adult in 10 to 14 days. They are most active from dusk to dawn and will fly up to 14 miles for a blood meal.
Mosquitoes as Vectors
These “vectors” are the #1 killers of human beings throughout the world:
- Malaria – from Anopheles species
- Yellow Fever – from Aedes species
- Dengue – from Aedes spp. (recent outbreak in Hawaii)
- Encephalitis diseases – many kinds, including West Nile Virus – most species are capable of spreading it, but Culex is the most important in New Jersey
