Many evidence confirms that the 3 main routes of Zika virus transmission are through mosquito bites, sex and blood transfusions.

According to CBS News (USA), the rapid spread of Zika virus to an alarming level has raised concerns and doubts about the infection pathways of this brain atrophy virus.

Zika virus disease is difficult to recognize when it is estimated that about 80% of people infected with Zika have no symptoms, including: mild fever, conjunctivitis, headache, joint pain and rash. In particular, Zika can cause brain atrophy for the fetus in the mother's stomach infected with the virus.

According to research by scientists, many evidence confirms that the three main routes of Zika virus transmission are through mosquito bites, sex and blood transfusions.

Mosquito bite

Dr. Tom Frieden, Director of CDC, said Aedes mosquitoes, which carry Zika virus, can suck blood from 4-5 people at the same meal, meaning it can spread disease quickly.

So far in the US, local health officials have reported at least 79 cases of Zika infection when traveling, meaning those people have gone to sick, infected areas and got sick right after returning home.

Sex

Health facilities around the world have recorded a number of sexually transmitted cases of Zika, including one in Texas, USA. According to the report, the person was infected with the virus after having sex with a patient who had just returned from Venezuela, where the Zika virus was outbreaking.

According to CDC, Zika virus may exist in male semen 10 weeks after the onset of the disease. Some people are infected but do not show signs of transmitting the virus to their sexual partners.

Therefore, CDC recommends that men who live or travel to Zika-affected areas should avoid sexual activity, or use preventive measures such as condoms, especially for pregnant women. to protect the fetus.

Blood transfusion

In the United States, large blood banks, including the American Red Cross, have asked people not to donate blood if they have just arrived in Mexico, the Caribbean, South or Central America within 28 days.

In addition, scientists also found Zika virus can be found in breast milk, saliva and urine . However, at this time, there has been no case of infection through these pathways.

On the afternoon of March 23, Mr. Tran Dac Phu, Director of Preventive Medicine Department, Ministry of Health, said Vietnam received information from the focal point of the International Health Regulation of the World Health Organization (WHO). ) announced in Australia to identify a case of Zika virus infection after returning from Vietnam.
