Dengue virus warning: Sickness could be spread by sex after shock find

A MAN who contracted Dengue fever after a trip to Thailand had the virus in his semen, even after he had healed from the illness, pointing to troubling new evidence that the disease, like Zika, can be contracted sexually.

A study by the National Institute for Infectious Diseases (INMI) detected the presence of the virus in an Italian man’s sperm.  

Dengue fever is caused by the Dengue virus and is usually contracted through mosquitoes. There is no cure for the illness.

The Dengue virus is part of the Flaviviridae family, the same scientific system that includes other viruses like Zika, Yellow Fever and encephalaitis, with extreme symptoms including neurological disorders, heart disease and liver failure.

The bite of a mosquito carrying the Zika virus can cause birth defects in babies as the virus can be passed from a pregnant woman to her foetus. Men can also pass the virus through their semen.

And now, like Zika, a new risk of men passing Dengue fever through sexual intercourse could become a reality.

The study, published in Eurosurveillance , shows for the first time the presence of the Dengue virus in the semen of a man who had recently healed following a recent infection with dengue

Researchers at INMI found that the virus persists in active replication in the seminal fluid and in particular in its cellular fraction up to 37 days after the onset of symptoms.  

Tests were performed at the Institute's virology laboratory using molecular biology techniques on the 50-year-old man, who returned from Thailand in January 2018 with the infection. 

Dengue fever’s symptoms include arthralgia, asthenia and nausea. The unnamed man still displayed symptoms after the ninth day of infection. 

Further virological investigations were performed on semen and urine samples. Semen is said to be able to hold up to 27 viruses at one time.

The institute's findings highlight the possibility of transmitting DENV through sexual intercourse, which could play a role in an infection spreading to non-endemic areas. 

Previously, no similar cases had been reported, that fact that in 2016 alone, 2,601 travel-associated dengue cases were reported to The European Surveillance System (TESSy) at the European Centre for Disease Prevention and Control (ECDC). 

However, the findings are yet to be corroborated. 

Further studies are yet to be carried out, in order to quantify and clarify the implications of genital shedding of DENV for non-vector sexual transmission.


Absence of proof is not proof of absence.

Dengue = 37 days without sex....not sure stopping that route of spread is going to work so well.  Maybe the first few days when feeling rotten and weak from the fever, but 37 days, NO way.
