The Zika virus is a viral disease transmitted by the Aedes mosquito, this mosquito is the same that transmits Dengue and Chikungunya, which was discovered in monkeys from the Zika forest of Uganda in Africa, hence its name. This virus is of the Flavivirus genus and belongs to the flaviviridaes family.
The first outbreak of the disease was detected and Zika was classified as an emerging infectious disease, capable of spreading to areas where the Aedes mosquito is present. And that was how in the virus reached Easter Island and later reached America.
How the Zika virus spreads
There are two types of Aedes mosquitoes, the aegypti that cannot survive in cold climates and the albopictus, which is capable of living in climates with lower temperatures. These mosquitoes become infected by biting and having contact with the blood of an infected person, in this way they will transmit the virus to a healthy person by biting again.
Other transmission mechanisms are usually:
1. From mother to child: If the mother is contaminated with the virus, at the time of delivery the baby will also be infected. It can occur even before birth since the virus is able to cross the placental barrier, on the other hand, it is important to inform the population that the virus cannot be transmitted through breastfeeding.
2. Through sexual contact: the virus can be transmitted from men to women through semen, since the half-life of the virus is longer in it than in blood.
3. Through blood transfusions: since the virus is present in the blood of infected people, through blood transfusion it passes directly into the bloodstream of the other person.
Also considered risk factors for contracting the Zika virus, having traveled to regions where there have been recent cases of infection.
Zika virus symptoms
Virosis generally has a benign course. The symptoms appear 7 days after the person has been infected by the mosquito, because this is the incubation period of the virus, where there are no symptoms and sometimes it can extend up to 12 days, this means that you will know that you have the disease 7 to 12 days after being stung.
This disease can present moderately or without symptoms and is usually characterized by the presence of specific symptoms such as:
· Fever or moderately elevated body temperature, which is why it is also known as Zika fever.
· Redness of the eyes without discharge or itching.
· Erythematous skin rash (red dots) that is usually less itchy than the rash caused by the Chikungunya virus.
· Sporadic joint pain, not as strong as those that occur in Chikungunya.
· Muscle aches and back pain
· Headache or headache
· In some cases, congenital neurological problems have been seen, cases of microcephaly have been observed in babies of mothers who had Zika during pregnancy.
They must also have a history of having been in countries with the presence of the Aedes mosquito or on Easter Island during the two weeks prior to the onset of symptoms, or that the patient's sexual partner has returned from a trip to places with mosquitoes of this species in the last month.
Zika Prevention and Treatment
The prevention of Zika is based on the reduction or elimination of mosquitoes by discarding the breeding places (rubbers that may contain rainwater, buckets of water without lids in the open, flowers or plants capable of retaining rainwater, etc.) because the mosquito needs water to reproduce.
The use of mosquito nets is also recommended to reduce contact between mosquitoes and people, the use of air conditioning, the use of repellants and finally it is recommended to protect doors and windows with metal mesh.
As it is a virus, the treatment is symptomatic, that is, the symptoms that appear will be treated. In most cases, hospitalization is not warranted and can be treated at home.
In general, it is recommended that the patient remain at rest, the intake of abundant fluids to replace possible losses, the use of acetaminophen or paracetamol as an antipyretic and analgesic, to calm fever and joint pain, muscle and headache is the first option.
The use of antihistamines or antiallergics is also recommended for squid itching associated with the rash.
If you present any other symptoms or if the patient's neurological status is very deteriorated, it is advisable to visit your doctor again.
