7 main symptoms of Zika vírus

Symptoms of Zika include low-grade fever, muscle and joint pain, as well as red eyes and red patches of skin. The disease is transmitted by the same mosquito as dengue, and symptoms usually appear 10 days after the bite.

Normally the transmission of the Zika virus occurs through the bite of the mosquito, but there are also cases of people who became infected through sexual contact without a condom. One of the biggest complications of this disease occurs when the pregnant woman is contaminated with the virus, which can generate microcephaly in the baby.

The symptoms of Zika are similar to those of Dengue, however, the Zika virus is weaker and therefore the symptoms are milder and disappear between 4 to 7 days.

Symptoms of Zika

The main symptoms that may be indicative of Zika virus infection are:

1. Low fever

Low fever, which can vary between 37.8°C and 38.5°C, occurs because with the entry of the virus into the body there is an increase in the production of antibodies and this increase raises the body temperature. So fever should not be seen as a bad thing, but as a sign that antibodies are working to fight the invading agent.

How to relieve: in addition to the remedies prescribed by the doctor, it may be useful to avoid very hot clothes, take a slightly warm bath to adjust the skin temperature and put cold cloths on the back of the neck and armpits, to lower body temperature.

2. Red spots on the skin

These occur throughout the body and are slightly elevated. They start on the face and then spread over the body and can sometimes be confused with measles or dengue, for example.At the medical center, performing the noose test can differentiate the symptoms of dengue, since the result will always be negative in case of Zika. Unlike dengue, Zika does not cause bleeding complications.

3. Itchy body

In addition to the small spots on the skin, Zika also causes itchy skin in most cases, however the itching tends to decrease in 5 days and can be treated with antihistamines prescribed by the doctor.

How to relieve: Taking cold showers can also help relieve itching. Applying cornstarch or fine oatmeal to the most affected areas can also help to control this symptom.

4. Joint and muscle pain

The pain caused by Zika affects every muscle in the body, and mainly occurs in the small joints of the hands and feet. In addition, the region may be slightly swollen and reddened, as is also the case with arthritis.The pain may be more intense when moving, less painful when at rest.

How to relieve: Medications such as Paracetamol and Dipyrone are useful for relieving this pain, but cold compresses can also help to deflate the joints, relieving pain and discomfort, in addition to In addition, one should rest whenever possible.

5. Headache

The headache caused by Zika mainly affects the back of the eyes, the person may have the feeling that the head is throbbing, but in some people the headache is not very severe or non-existent.

How to relieve: Placing cold water compresses on your forehead and drinking warm chamomile tea can help relieve this discomfort.

6. Physical and mental fatigue

With the immune system acting against the virus, there is a greater energy expenditure and consequently the person feels more tired, with difficulty moving and concentrating.This occurs as a form of protection so that the person can rest and the body can focus on fighting the virus.

How to relieve: you should rest as much as possible, drink plenty of water and oral rehydration serum, similar to the amount recommended for the treatment of dengue, and evaluate the possibility of not attend school or work.

7. Redness and tenderness in the eyes

This redness is caused by increased periorbital blood flow. Despite being similar to conjunctivitis, there is no yellowish discharge, although there may be a slight increase in tear production. In addition, the eyes are more sensitive to daylight and it may be more comfortable to wear sunglasses.

What to do in case of suspicion

When there is a suspicion of having Zika, it is recommended to go to the hospital immediately so that the doctor can observe the symptoms and assess whether they may be caused by the Zika virus.

In addition, the doctor may also order some tests to ensure that there is no other disease that could be causing the same symptoms.
