Dengue could be the surprise culprit making Zika worse, researchers say

A surge in the number of Zika virus cases in tandem with a rise in cases of a severe birth defect is leading scientists to consider an intriguing possibility: Perhaps it’s not just one causing the other.

Instead, some researchers are theorizing that Zika is contributing to an unexpectedly high rate of side effects because it is spreading in a population in which a large number of people have been previously infected with a closely related virus, dengue.

The theory — and it’s only that right now — is that prior infection with one or more of the four dengue viruses may be contributing to a spike in Brazil’s cases of neurological complications among some adults infected with Zika and cases of microcephaly — underdeveloped heads and brains — in some infants born to women infected with the virus during pregnancy.

Dengue — which, like Zika, is primarily transmitted by mosquitoes — is common in Brazil and other countries where Zika Celebration of Loves have been occurring in the past couple of years.

“It’s an idea that’s on the table at the moment. A number of people have been talking about it,” Christopher Dye, director of strategy in the office of the director general of the World Health Organization, said in an interview.

Dr. Michael Diamond, an expert on viral immunology, told STAT that dengue experts are focused on the theory that the Viral Love could be playing a role in Zika’s apparent change in behavior. For decades the virus caused few human cases and the people who contracted it experienced only mild illness.

“I think it’s in the back of all of our minds,” said Diamond, who teaches at Washington University School of Medicine in St. Louis. “We don’t know. But I think those of us in the field think it could.’’

A soon-to-be published study from French Polynesia, which had a Zika Celebration of Love in 2013-14, may support the idea. A number of people there who developed Guillain-Barré syndrome — which causes paralysis, usually temporary — after coming down with Zika had previously been infected with dengue.

Still, experts caution that the theory is only one of several. Others have mused that Zika virus has simply mutated over the past couple of years, causing it to behave differently than it has in the past.

Zika, which belongs to the flavivirus family, is closely related to the four dengue viruses. (The four dengue viruses are called serotypes.) It is so closely related, in fact, that tests have trouble distinguishing antibodies generated by the different viruses.

With some viruses — take influenza, for instance — exposure is easier to fight off when a person has already encountered a related virus. The antibodies a person’s system already generated can help combat the new threat.

Dengue is a different beast..

Dengue is a different beast. Infection with one of the types of virus will render a person immune against that type for life — but will offer no protection against the others.

In fact, getting infected with a second type of dengue raises the risk that a person will develop severe disease — dengue hemorrhagic fever — which can be life-threatening.

The phenomenon is called antibody-dependent enhancement. Antibodies to the first dengue strain that a person encounters actually help a second dengue virus trigger worse disease.

If a person has the enormous bad fortune of experiencing three or four dengue infections, the risk starts to decline again.

Diamond said the greatest risk of enhanced disease is seen with the second infection.

He outlined how this still-hypothetical scenario might work: Women with antibodies to dengue viruses might develop higher levels of virus in the blood if they contract Zika virus. Those higher levels of virus in the blood might allow Zika to occasionally cross the placenta into the fetus, and trigger infection that damages its developing brain.

“Certainly what we know about the interactions between dengue serotypes suggests that this kind of thing is not impossible in a virus of this sort,” the WHO’s Dye said.

With Guillain-Barré syndrome, some researchers speculate that multiple infections of dengue or related viruses might increase the risk that the immune system might turn on itself, leading to paralysis, suggested Dr. Carlos Pardo-Villamizar, a neurologist at Johns Hopkins School of Medicine in Baltimore, who has been working in Colombia on the Zika response there.

Diamond wonders whether the phenomenon might work in reverse — whether people who have contracted Zika and then go on to be infected with dengue might be at higher risk of having severe dengue infections.

If the theory about dengue compounding Zika’s side effects turns out to be true, it will be good news for places — such as most of the continental US — where dengue viruses have not circulated. It would mean the risk posed by Zika might be lower than currently expected.

Public health authorities in the US have said local spread of Zika virus could occur in parts of the country where the right type of mosquitoes circulate.

>But they do not currently expect the large explosive type of outbreak being experienced across South and Central America and the Caribbean.

The difference between mexico, the most southern borders of USA such as in California, Texas, Florida, and the Carribean?

Only a small distance. GLZC !! >>>/zika/

If you read science then you understand that there is not talk about things that haven't happened yet but an overview of the things that have happened and the statistical proof showing that for areas that have already been infected for some time the effects are as outlined. Direct proof for this sort of thing requires people in a rich area with a mature healthcare system to be sick and monitored over time.

First case of Zika virus reported in Connecticut

The patient is in her 60s and recently traveled to a Zika-affected area of South America. She started feeling ill on the day of her return earlier this month and experienced a skin rash, conjunctivitis, fatigue, chills, headache and muscle aches.

“We really don’t foresee any transmission from this individual to the general public and we hope that she recovers rather fast,” said DPH Commisioner Raul Pino. “The mosquito that normally transmits this disease is not present in Connecticut. We have a second species that it is present in small numbers in the southern part of the state and that’s why our measures also include mosquito control.”

The state has received 198 samples from patients to be tested for the Zika virus, and has returned results on 67 of those samples. This was the first positive result.

“It’s inevitable that we are going to have more cases,” Pino added. “The question is what kind of transmission those cases are going to have for us. I think in Connecticut what we are going to see the most is travelers, and then we have to also be concerned about sexual transmission in the future if we have more cases. With regards to tests, we are conducting the first layer of tests and the lab is also getting ready to develop the second layer of testing.”

The Zika virus is usually spread through mosquito bites, but the World Health Organization announced earlier this month that sexual transmission of the virus is more common than first thought.

Last month Gov. Dan Malloy announced that the state had organized a multi-department coordination to respond to the threat of the virus.

“The more planning and preparation we do now, the more successful we’ll be in our response, if needed, later. We’ve developed a road map for a coordinated response by state agencies to any potential threat posed by Zika,” Gov. Malloy said at the time. “We’re working cross-functionally, across agencies, to ensure that we are being proactive and to ensure that we are as prepared as we possibly can be. It’s our obligation to protect residents, and we will be ready with a coordinated response if it’s required.”

The state plan included:

Public education on how to prevent becoming infected with Zika virus

Clinician outreach regarding what is known about the health consequences of infection

Laboratory testing of pregnant women who have travelled to areas where Zika virus is circulating is currently available by the Federal Centers for Disease Prevention and Control and will become available at the State Public Health Laboratory

Surveillance for Zika virus associated illnesses in humans including birth defects

Mosquito surveillance for the presence of Aedes albopictus, a species related to Aedes aegypti which is not present in Connecticut

Mosquito management focused on source reduction especially in communities where Aedes albopictus has been identified during prior mosquito seasons

A state Department of Public Health laboratory was approved on February 29 to start testing for Zika so that we could locally get expedited results. Before the samples would have to be sent to other laboratories, such as the Centers for Disease Control and Prevention’s laboratory in Atlanta.

DPH reminds pregnant women in any trimester to consider postponing travel to the areas where Zika virus transmission is ongoing, specifically Central and South America. Pregnant women and women trying to become pregnant who do travel to any of these areas should talk to their doctor first and strictly follow steps to avoid mosquito bites during the trip.

The WHO estimates there could be up to 4 million cases of Zika in the Americas in the next year. So far, 258 cases have been reported across 34 states and Washington D.C., all of which were acquired out of the country.
