Cholera Outbreak – Haiti, October 2010

MMWR Dispatch  October 28, 2010  Volume 59

An outbreak of cholera is ongoing in Haiti. As of October 27, a total of 4,722 cholera cases and 303 deaths had been reported. Most cases have been reported from the Artibonite Department, a rural but densely settled area with several small urban centers. In addition, probable cases have been identified elsewhere in Haiti, including Ouest Department, where the capital city of Port-au-Prince is located. An international public health response, led by the Ministry of Public Health and Population in Haiti and including technical support from the Pan American Health Organization, CDC, and other governmental and nongovernmental organizations, is under way.

Transmission of Hemagglutinin D222G Mutant Strain of Pandemic (H1N1) 2009 Virus

Emerging Infectious Diseases May 2010  V.16  N.5  p.863-865

Zanetti); Università degli Studi di Milano-Bicocca, Milan (R. Fumagalli); and Università degli Studi di Parma, Parma, Italy (M.L. Tanzi)


A pandemic (H1N1) 2009 virus strain carrying the D222G mutation was identified in a severely ill man and was transmitted to a household contact. Only mild illness developed in the contact, despite his obesity and diabetes. The isolated virus reacted fully with an antiserum against the pandemic vaccine strain.

To the Editor: In March 2009, a new strain of influenza A (H1N1) virus of swine origin emerged; the virus had crossed the species barrier to humans and acquired the capability of human-to-human transmission. Soon after, the World Health Organization raised the worldwide pandemic alert to level 6 (, declaring the first influenza pandemic in the past 42 years. The virus was named influenza A pandemic (H1N1) 2009 virus. The illness caused by this virus is particularly dangerous for pregnant women and for patients with chronic diseases (1). The preferred treatment is a neuraminidase inhibitor, zanamivir or oseltamivir

Co-infection with Dengue Virus and Pandemic (H1N1) 2009 Virus

To the Editor: Dengue is a mosquito-borne viral infection caused by 4 related dengue viruses. Each of these viruses is capable of causing classic dengue fever or dengue hemorrhagic fever (DHF), but may also cause nonspecific febrile illnesses. As a result, dengue is often difficult to diagnose clinically, especially because peak dengue season often coincides with that of other common febrile illnesses in tropical regions (1). Concurrent outbreaks of influenza and dengue have been reported (2,3); this circumstance often leads to delayed recognition of the presence of one or other disease in the community…

Triatoma infestans Bugs in Southern Patagonia, Argentina

Emerging Infectious Diseases May 2010  V.16  N.5  p.887-889

To the Editor: Triatoma infestans bugs, the main vector of Chagas disease, historically occupied a large area from northeastern Brazil to Chubut Province in Patagonia, Argentina (1). Large-scale insecticide spraying during the 1980s and 1990s reduced its geographic range and abundance and interrupted transmission of Trypanosoma cruzi, mainly in Uruguay, Chile, and Brazil (2). However, T. infestans and transmission of T. cruzi persist in the Gran Chaco, a large ecoregion in Argentina, Bolivia, and Paraguay …

Guideline-concordant therapy and reduced mortality and length of stay in adults with community-acquired pneumonia: playing by the rules.

Arch Intern Med. 14 Sept 2009  V.169  N.16   p.1525-31

Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality worldwide. Clinical practice guidelines for empirical CAP treatment, formulated jointly by the Infectious Diseases Society of America (IDSA) and American Thoracic Society (ATS), remain controversial and inconsistently applied. We evaluated the impact of guideline-concordant therapy on in-hospital survival and other outcomes using a large database including adults treated for CAP in both community and tertiary care hospitals.


We evaluated the association between in-hospital survival and guideline-concordant therapy using logistic regression models. Time until discharge from hospital and discontinuation of parenteral therapy were evaluated using survival analysis.


Of 54 619 non–intensive care unit inpatients with CAP hospitalized at 113 community hospitals and tertiary care centers, 35 477 (65%) received initial guideline-concordant therapy. After adjustment for severity of illness and other confounders, guideline-concordant therapy was associated with decreased in-hospital mortality (odds ratio [OR], 0.70; 95% confidence interval [CI], 0.63-0.77), sepsis (OR, 0.83; 95% CI, 0.72-0.96), and renal failure (OR, 0.79; 95% CI, 0.67-0.94), and reduced both length of stay and duration of parenteral therapy by approximately 0.6 days (P < .001 for both comparisons). These findings were robust with alternate definitions of “concordance” and were linked to treatment with fluoroquinolone or macrolide agents.


Guideline-concordant therapy for CAP is associated with improved health outcomes and diminished resource use in adults. The mechanisms underlying this finding remain speculative and warrant further study, but our findings nonetheless support compliance with CAP clinical practice guidelines as a benchmark of quality of care.
