Asian tiger mosquitoes discovered in Windsor (Canada) trap

Two adult aedes albopictus mosquitoes were found in a single local surveillance trap, said Health officials on the lookout for the presence of mosquitoes capable of transmitting the Zika and West Nile viruses.

asian tiger mosquito

This kind of mosquito, also known as the Asian tiger mosquito, can transmit viruses including Zika, Chikungunya or west nile virus.

A lab analysis determined these two mosquitoes were not carrying West Nile or Zika nore chikungunya.

During the surveillance program last year, 17 Asian tiger mosquitoes were trapped locally and none had Zika or West Nile. In the fall, the health unit reported it had also discovered aedes aegypti larvae. This species of mosquito, also known as the yellow fever mosquito, is responsible for most of the Zika cases in the Caribbean, South America and Florida. The mosquitoes that officials reared from the aedes aegypti larvae all tested negative for Zika.

The Asian tiger mosquitoes have been found across the U.S., including in areas with climates similar to here, like Vermont, New York, New Hampshire and Massachusetts.

The two found this summer may be from a new colony — perhaps transported from the U.S. in shipping containers or cross-border trucks — or they may have originated from last year’s colony, which may have survived the winter because of the mild weather.

“The discovery of the Asian tiger mosquitoes again this year is an important reminder to everyone that we should continue to protect ourselves and our families from mosquito bites,” acting medical officer of health Dr. Ahmed said in the news release.

Until freezing temperatures arrive, it’s important to take precautions against mosquito bites, the health unit says. These include: using insect repellents containing DEET, Icaridin or other approved ingredients; wearing long pants, long-sleeved shirts and hats when outdoors; and making sure window screens and doors don’t have any holes or other openings that allow mosquitoes to get indoors.

Would chikungunya drive the luxury tourists away ?

At the Taina marina, yacht charter high season was shortened to eight weeks because of the chikungunya epidemic, which has driven international clients in November of businessmen and multinational employers. “The mega yacht Noble House, which rents 250,000 dollars a week, was used only four weeks since August, the Tuamotu and Bora Bora, in his first season in Tahiti, says Etienne Boutin, manager the company Tahiti Ocean. And again, this is because the contracts were signed before the explosion of the epidemic. Since then, we have more requests. ”
Yet this boat 52 meters generally good press from foreign rich. It will soon be leaving the dock it is not certain that it will retry the Polynesian experience, then it is highly demanded in Fiji.
On Douce France, it’s even worse. This boat is one of the largest luxury sailing catamarans in the world. It measures 43 meters long, has two high masts of 42 meters each, and includes eight crew members, six luxury cabins with marble bathrooms and a 250-bottle wine cellar.
This impressive catamaran had come to spend the season in Polynesian waters for the first time since 2006 and despite its lower price than Noble House (150 000 dollars a week) “no one has even praised” says Etienne Boutin.

Despite the economic downturn, manage Tahiti Ocean wants to remain optimistic: “We hope that the chikungunya epidemic will be completed in April-May and this will be announced in the media worldwide as when it starts. It should then bringing back our customers. ”

Chikungunya epidemic decrease in Tahiti

Twice fewer cases than last week in Tahiti

About a thousand new probable cases of chikungunya have been identified by the Health Surveillance Office Country last week of January 2015, against more than 2,000 the week before. This seems to confirm the net decline of the epidemic on the Windward Islands, the Leeward Islands and Tuamotu Gambier.

Pic in the Austral?

The circulation of the virus is still very active in the Austral contrary: the southernmost island of French Polynesia reported 160 new cases of chikungunya in the last week of January, which is currently the peak on highest recorded in the Austral, especially in Rurutu.

Decrease the Marquesas

In the Marquesas finally there were 450 new cases of chikungunya identified during the last week of January is still a lot, but again the decay begins. There was indeed more than 1,000 new cases during the third week of January and more than 800 the following week.

A quarter of the population would have consulted

Overall, the country’s health authorities estimate that a quarter of the Polynesian population consulted for the first clinical signs of chikungunya since the declaration of the epidemic in October 2014. Since the beginning of the epidemic, 938 cases were hospitalized for reasons related infection chikungunya virus (including 6.5% for severe forms). Furthermore, seven cases of Guillain-Barre Syndrome (GBS) have been identified as being related to an earlier chikungunya infection.

Transgenic mosquitoes in Florida this year 2015 ?

will Tigers GM Mosquitoes be used in Florida?

Florida is studying the possibility of releasing three million genetically modified tiger mosquitoes over 6 months. This measure aims to fight against chikungunya, a disease transmitted by this insect, which causes high fever and severe pain. Indeed, the idea is to introduce males whose offspring is not sustainable in nature in order to reduce the number of insects. Oxitec (The company that launched this experiment) conducted several trials in Brazil and the Cayman Islands. The company ensures that these tests showed a reduction of more than 90% of the populations of the Aedes aegypti. On the basis of these results, the US Medicines Agency (FDA) could give discharge to the project. Oxitec could then begin to release these GM mosquitoes into the wild in the next few months, with several times a week.

Raising shields in Florida

Opponents of the “mutant mosquito” are concerned about the environment and their potential impact on humans and other animal species. They also question the fact that a group of independent experts did not consider the British firm’s research. They argue that there have been no cases of dengue in the Keys for years, which shows the effectiveness of current mosquito population control methods. While the Office of mosquito control in the archipelago of the Florida Keys has agreed to work with Oxitec who built a GM mosquito breeding laboratory, more than 145,000 people have now signed a petition urging the authorities object to the state become “a place of experimentation with these mutant insects”

First local dengue case in France

Yesterday, thursday, augut 21st, the regional health agency confirmed the first autochtone dengue case in France this year, in the Var department.

It is for now an isolated case, and the contamined person visited his doctor, who confirmed that there’s nothing to worry about his health.

An autochtone case means that the person has contracted the virus on national territory and has not traveled in a contamined zone (in another country) during the 15 pervious days.

Dengue, like chikungunya, is a desease due to a virus that can be transmitted by the tiger mosquito bite.

The Var department has officially been promoted to level 2 of anti dissemination plan for dengue and chikungunya. This means that demoustication actions have been planed all around the residence zone of this contamined person.

As a reminder, two cases of dengue autochtone cases had been confirmed in 2010 in France, and also 2 chikungunya autochtone cases.

First Local Chikungunya Cases in United states

The first locally acquired case of chikungunya in the continental United States

Health officials confirmed : “Chikungunya has been reported in a Florida man and woman who had not recently traveled”
This confirmation is the first indication that the chikungunya virus may have taken up residence in the United States.

Health experts had said it was only a matter of time before the virus, carried by asian tiger mosquito, made its way to the U.S.
This moquito is spreading rapidly in the Caribbean and Central America, and even in New York
Usually, U.S. cases happen for people who had recently traveled to affected regions, but this time, it’s a local case. The first local case.

Two cases are officially delcared : one in Palm Beach County (a 50-year-old man), and one in Miami-Dade County (a 41-year-old woman)

“Since 2006, the United States has averaged 28 imported cases of chikungunya (chik-un-GUHN-ya) per year in travelers returning from countries where the virus is common. To date this year, 243 travel-associated cases have been reported in 31 states and two territories,” CDC said.

“However, the newly reported case represents the first time that mosquitoes in the continental United States are thought to have spread the virus to a non-traveler. This year, Puerto Rico and the U.S. Virgin Islands reported 121 and two cases of locally acquired chikungunya respectively.”

More info on dengue virus and chikungunya virus.

The Aedes aegypti and Aedes albopictus (also know as tiger mosquito) mosquitoes that spread chikungunya are found across the southern United States and as far north as New York.

There is a huge difference between a traveler carrying it and a locally transmitted case :

  • First case : a person comes from infected country with the virus and becomes sick un US. End of story.
  • econd case : a person comes from infected country with the virus and becomes sick un US. The perso is bitten by a tiger mosquito, which transmits the virus to another person

The second case is mutch more worrying, because what happen here proves that the virus could spread and infecte several dozens of persons allover Miami or Palm Beach, or even thousands of persons allovers the United states (see what happened in 1999with West Nile virus).

“The arrival of chikungunya virus, first in the tropical Americas and now in the United States, underscores the risks posed by this and other exotic pathogens,” said Roger Nasci, who heads CDC’s Arboviral Diseases Branch. “This emphasizes the importance of CDC’s health security initiatives designed to maintain effective surveillance networks, diagnostic laboratories and mosquito control programs both in the United States and around the world.”

CDC and the Florida Department of Health said they are looking for other locally acquired cases. “More chikungunya-infected travelers coming into the United States increases the likelihood that local chikungunya transmission will occur.”

Chikungunya coming soon to United States ?

Chikungunya virus is spreading in the “Antilles” indecember/january

During the last days of december and first day of janvier 2014, the chikungunya virus is spreading in the “antilles”. It’s now confirmed in Martinique, Guadeloupe and Guyane, after it had infected Saint Martin in décembre (with two dead people). One case is waiting for confirmation at Saint-Barthélemy. The virus origin seems to be asiatic, and is different from the one that had spread in “La Réunion” in 2005 et 2006. A large spread is possible in the Etats Unis, said specialists.

Spread in the United States ?

“The situation is potentially explosive”, said Pr Xavier de Lamballerie to the AFP (Agence France Press). “There is an extremly high risk that this chikungunya virus spread in the United States and some other countries of South America”. Indeed, a mosquito called “Aedes Aegypti” is endemic from those regions and can carry this virus.

The outbreak represents the first known indigenous transmission of chikungunya fever in the Americas. The ECDC said that the outbreak underscores the recommendations it made earlier this month, urging health providers to heighten their vigilance against the disease, especially with increased travel during the holidays.

New York man contracts dengue fever from local mosquito

For the first time ever, someone in New York State contracted dengue fever locally, health officials said. You get dengue virus from a mosquito bite. That means he got the virus from a local mosquito that probably had previously bitten an infected traveler.

Dengue can cause illness and death in tropical and subtropical countries in some conditions.

“The exact route of transmission in this case is unknown,” said Dr. James Tomarken, “However, we have determined that this individual acquired dengue virus locally, as he had not traveled outside of the local metropolitan area during the incubation period.” Recent other dengue infections had more liekly happened while those patients were travelling in other countries.

The dengue fever can be spread by two mosquitoes : aedes albopictus (also known as asian tiger mosquito) and aedes aegypti.
