The2009 Bolivian dengue fever epidemic was anepidemic ofdengue fever which struckBolivia in early 2009, escalating into a national emergency by February. TheBBC described it as the worst outbreak of dengue fever in the country's history. At least 18 people died and 31,000 were infected by themosquito-transmitted arbovirus.
On 20 February, thePan American Health Organization reported that eighty (80) cases of the more severe dengue hemorrhagic fever had occurred in Bolivia since January, of which 22% were fatal.[1] Bolivia requested outside assistance and foreign aid.
Bolivia first declared a national emergency in early February 2009, when it alerted the world about the country's worst outbreak of dengue fever in twenty-two years.[2] By 3 February, five people had died in the east of the country and over 7,000 more were infected.[2] Worst hit is theSanta Cruz Department, near theParaguayan border and theAmazon.[2] A number of military facilities, particularly in the city ofSanta Cruz, were turned into temporary hospitals as the real hospitals struggled to cope with the conditions.[2] Thousands of soldiers were mobilized to assist medical workers.[2] The government then allocated funds to supply hospitals across the country; however, it was criticised in some quarters for the slowness of its actions.[1][2] The infection was most widespread in the tropical eastern lowlands, where conditions led to a thriving mosquito population.[1] Bolivia's healthcare services had difficulty in coping with the outbreak, with experts fromVenezuela,Cuba,Paraguay and theWorld Health Organization called in to assist.[1]
Hirofumi Nakasone,Japan'sMinistry of Foreign Affairs planned to send seven millionyen in emergency relief goods.[1]Mosquitoes thrive in the high temperatures and humidity of the Bolivian lowlands and it was that region which saw the highest numbers of infected civilians.[1] There is currently no vaccine for dengue fever.[1] Those infected experience flu-like symptoms such as severe headaches, fevers and joint pain.[1] 1 of 4 people infected with dengue will develop symptoms.[3] There is no specific treatment for dengue, other than managing the symptoms. The best way to address dengue is to disrupt the mosquito's habitat. Mosquitos breed in stagnant water, i.e. open storage containers, discarded tires, and uncollected garbage.[4] The infected are advised by medical experts to drink plenty of fluids and obtain significant rest.[1] Dengue fever sufferers have an approximate 1% chance of progressing to the more severe dengue hemorrhagic fever.[1] 1 of 20 individuals who become ill with dengue will develop severe dengue. Severe dengue can lead to life-threatening condition including shock, internal bleeding, or death.[3] Other symptoms includehypothermia, vomiting, severe abdominal pain and confusion. The global average case-fatality ratio for dengue hemorrhagic fever is 5%.[1]
