TRANSMITTED DISEASES
The Aedes aegypti mosquito is responsible for the transmission of dengue, chikungunya, zika and yellow fever viruses, among other viruses that it transmits in different regions of the world.
DENGUE
THE SYMPTOMS ARE:
-
Between 3 and 14 days after the bite of the infected mosquito, a high fever (more than 38.5 °C) appears.
-
Very intense headache.
-
Pain behind the eyeballs.
-
Nausea.
-
Vomiting.
-
Pain in muscles and joints.
-
Enlargement of lymph nodes.
-
Rash.
MORE INFORMATION:
-
Dengue is a viral disease caused by a virus transmitted by the Aedes aegypti mosquito, vector of the disease.
-
Its symptoms appear between 3 and 14 days after the bite of the infected mosquito. A high fever appears (+ 38º).
-
Symptoms are: very severe headache, pain behind the eyeballs, nausea, vomiting, muscle and joint pain, enlarged lymph nodes, rash.
-
With two of these symptoms we must consult the doctor. Identifying the warning signs allows us to begin early intravenous fluid replacement and prevent shock, with a consequent reduction in mortality.
CHIKUNGUNYA FEVER
THE SYMPTOMS ARE:
-
High fever.
-
Headache.
-
Muscle and joint pain 3 to 7 days after being bitten by an infected mosquito.
-
Joint pain can last longer.
-
Its incubation can last from 3 to 7 days.
MORE INFORMATION:
-
Chikungunya fever is a viral disease also transmitted by the infected Aedes aegypti mosquito.
-
Symptoms appear about 3 to 7 days after being bitten by an infected mosquito.
-
The presence of chikungunya should be suspected when high fever, joint pain, and skin rash appear.
-
In most infections that occur during pregnancy, the virus is not transmitted to the fetus.
-
It can rarely cause death.
-
Non-steroidal anti-inflammatory drugs (ibuprofen, diclofenac) are contraindicated.
-
If there is vomiting, it is recommended to drink plenty of fluids and rest.
YELLOW FEVER
THE SYMPTOMS ARE:
-
Fever.
-
Headache.
-
Muscle pains.
-
Vomiting.
-
Jaundice.
-
In most cases the symptoms disappear after 3 or 4 days.
-
If the disease progresses, high fever returns, the gums may bleed, there may be blood in the urine or it may be dark in color, and intense abdominal pain may appear.
MORE INFORMATION:
-
Yellow fever is prevented with a very effective, safe and accessible vaccine. A single dose is enough to acquire lifelong immunity and protection. Thirty days after its application, the vaccine is effective in 99% of vaccinated people. Those who live or visit risk areas should get vaccinated.
-
Many cases of yellow fever are asymptomatic.
-
The initial symptoms are similar to those of the flu: fever, headache, muscle aches, vomiting. In most cases the symptoms disappear after 3 or 4 days.
-
If the disease progresses, high fever returns, the gums may bleed, there may be blood in the urine or it may be dark in color, and intense abdominal pain may appear.
-
Yellow discoloration of the skin and eyes may occur in some patients.
ZIKA
THE SYMPTOMS ARE:
-
Fever less than 39°.
-
Headache.
-
Muscle weakness and pain in the joints.
-
Inflammation (in hands and feet).
-
Non-purulent conjunctivitis.
-
Edema in the lower limbs.
-
Skin rash (tends to start on the face and then spreads throughout the body).
-
Less commonly, vomiting, diarrhea, abdominal pain, and lack of appetite occur.
-
Its incubation can last from 3 to 12 days.
MORE INFORMATION:
-
Zika is transmitted like the rest of the diseases, through the infected Aedes aegypti mosquito, but it has the particularity that other forms of transmission are added: from the pregnant mother to the baby (vertical transmission) and through sexual relations. Therefore, its presence is of great concern.
-
After being bitten by the infected mosquito, incubation can last between 3 and 12 days.
-
In 70 to 80% of cases, infected people do not show symptoms.
-
The person may have a fever of less than 39 °C, headache, weakness, muscle and joint pain, inflammation that is usually concentrated in the hands and feet, non-purulent conjunctivitis, edema in the lower limbs and skin rash, which tends to start on the face and then spreads throughout the body.
-
Less frequently, vomiting, diarrhea, abdominal pain and lack of appetite may occur.
-
Pregnant women should take extreme prevention measures due to the risk of fetal malformations such as microencephaly.
-
People of reproductive age should use condoms to prevent sexual transmission of the virus.
