Paraguay confirms domestic case of chikungunya

Paraguay on Tuesday confirmed the first domestically-acquired case of chikungunya, a woman who became infected after contact with a couple who contracted it in Puerto Rico, bringing to four the number of people in the country with the virus, Dr. Andrea Ojeda, the spokesperson for the Health Monitoring agency, told Efe.

Ojeda said that the Asuncion resident is in the subacute phase of the disease, experiencing joint pain but not infectious.

The doctor added that the woman works as a housekeeper for two people who had picked up the virus during a trip to Puerto Rico, a pair of cases that were detected in late October at a private health clinic in the Paraguayan capital.

Including the couple, there are now three imported cases of chikungunya in Paraguay, after a person coming from the Dominican Republic was found to be infected in September.

At the end of last month, the Public Health Ministry urged the public to avoid travel to countries reporting cases of chikungunya, including Brazil, Colombia, Venezuela and the nations of Central America and the Caribbean, as a way of preventing the virus from making its way to Paraguay.

The landlocked South American nation is currently in the season where there is a high risk of dengue outbreaks, as well as the potential for importing chikungunya, both of which are transmitted by the Aedes aegypti mosquito, the ministry said. EFE

Rh negative people more resistant to chikungunya

Rh positive blood groups are more susceptible to chikungunya fever over Rh negative individuals are resistant to it, a new study suggests. Also, people with ‘O’ positive blood group are more susceptible to infection by the virus than people of other blood groups, the research says.


The researchers studied genetic predisposition to chikungunya fever, based on blood group antigens, on 100 families affected by the disease. They conducted blood group (ABO) tests by focusing on individuals who were likely to have a risk of chikungunya and identified the blood group involved in susceptibility/resistance to chikungunya.

The individuals were screened under four groups — A, B, AB and O. The result obtained showed that all Rh positive blood group individuals were susceptible to chikungunya fever.

Among ABO groups, O +ve individuals were found to bemore susceptible to chikungunya than other blood groups. No blood group with Rh negative was affected with chikungunya, indicating more resistance to chikungunya.

Chikungunya (pronunciation: \chik-en-gun-ye click to hear pronunciationExternal Web Site Icon) virus is transmitted to people by mosquitoes. The most common symptoms of chikungunya virus infection are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Outbreaks have occurred in countries in Africa, Asia, Europe, and the Indian and Pacific Oceans. In late 2013, chikungunya virus was found for the first time in the Americas on islands in the Caribbean. Chikungunya virus is not currently found in the United States. There is a risk that the virus will be imported to new areas by infected travelers. There is no vaccine to prevent or medicine to treat chikungunya virus infection. Travelers can protect themselves by preventing mosquito bites. When traveling to countries with chikungunya virus, use insect repellent, wear long sleeves and pants, and stay in places with air conditioning or that use window and door screens

The number of autochthonous chikungunya cases rose by nearly 50,000 cases in the Caribbean and Latin America during the past week with the total such cases now topping 350,000. Of the 355,617 locally acquired cases reported, Hispaniola accounts for 245, 257 cases (Dominican Republic with 193,413 and Haiti with 51,844), accounting for 69 percent of cases.

Health and Disease journalist, Chuck Simmins reports that in the United States to date, The Centers for Disease Control (CDC) announced July 8 that they have received reports of 153 cases of chikungunya in U.S. However, he notes that a compilation of state reports show that the continental U.S. has 42 more cases than in the CDC report. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page

What is the current situation of chikungunya 28th Aug 2014

In December 2013, the World Health Organization (WHO) reported local transmission of  in Saint Martin. Local transmission means that mosquitoes in the area have been infected with chikungunya and are spreading it to people. This is the first time that local transmission of chikungunya has been reported in the Americas.

Local transmission of chikungunya is now being reported in other countries in the Caribbean. As of August 11, 2014, the following Caribbean countries have reported cases of chikungunya:

The Centers for Disease Control and Prevention released the latest numbers yesterday concerning both imported and locally-acquired chikungunya cases on the continental United States, Puerto Rico and the US Virgin Islands.  As of July 22, a total of 497 chikungunya cases have been reported to ArboNET from U.S. states and territories.

The data reported to ArboNET, as of July 22 shows that 70 percent of the states have reported imported, or travel associated chikungunya cases. One quarter of the 300 imported cases have been reported from Florida. Countries or territories visited include Anguilla, Dominica, Dominican Republic, Guyana, Haiti, Indonesia, Martinique, Puerto Rico, Saint Barthelemy, Saint Martin, Sint Maarten, and Tonga.

In addition to the continental US, the CDC shows the numbers from Puerto Rico and US Virgin Islands. Of the 197 autochthonous case recorded, 98 percent were seen in Puerto Rico.

Locally acquired case were also seen in Florida (2) and the US Virgin Islands (2). For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page

From 2006‒2013, studies identified an average of 28 people per year in the United States with positive tests for recent chikungunya virus infection (Range 5‒65 per year). All were travelers visiting or returning to the United States from affected areas, mostly in Asia. Only a quarter of the cases were reported to ArboNET.

Chikungunya outbreak expands by 12%, to 576,000 cases

Officials reported more than 62,000 new chikungunya cases in the Caribbean and surrounding areas last week—almost all in the Dominican Republic—expanding the outbreak to 576,000 cases, according to an Aug 8 update from the Pan American Health Organization (PAHO).

The total represents an increase of 62,608 suspected and confirmed cases, or 12.2% of the 513,393 reported a week earlier. Of the total, only 646 are imported cases, with the rest locally acquired.

The Dominican Republic accounted for 62,279 of the new cases, to bring its outbreak total to 370,212, according to PAHO.

The update also included 100 new imported and 2 new locally acquired cases in the United States that were confirmed by the US Centers for Disease Control and Prevention (CDC) last week. In addition, Puerto Rico reported 734 new locally acquired cases to bring its total to 1,982, plus 17 imported cases.

Caribbean islands that had previously been driving the outbreak numbers—such as Martinique, Guadeloupe, and St. Martin—reported no new cases. Most involved islands and nations, however, are several weeks behind on reporting cases.

Countries reporting their first chikungunya cases were Canada, with 8 confirmed imported cases, and Curacao, with 9 imported cases, 1 of which was confirmed. In addition, Jamaica confirmed its first 2 locally acquired cases; it earlier had reported 2 imported cases.

The outbreak’s death toll remained at 32.

chikungunya in 6 state in the us so far

US health officials are on high alert as a mosquito-borne virus that yet has no cure has struck six of the US states. The virus called chikungunya

causes severe joint pain which can last for years.

Symptoms of the malaria-like illness include fever, headache, chills, sensitivity to light, and rash, vomiting and severe joint pain, according to
World Health Organization (WHO). Occasional cases of eye, neurological and heart complications have been reported, as well as gastrointestinal
complaints, it adds. They usually begin three to seven days after infection occurs. The consequences include a long period of joint pains which may
persist for years in some cases.

Incurable chikungunya virus spreads in US, at least 6 states affected

I know it’s RT, but i came across it and thought it wise to share with the members here.

The states currently affected with the virus include:

Rhode Island
North Carolina
(US Virgin Islands)

The virus rarely leads to death, but it is incurable, meaning that if you get it, you’re going to have to put up with it.
