Multidrug-Resistant Aspergillus fumigatus Carrying Mutations Linked to Environmental Fungicide Exposure - Three States, 2010-2017.

The environmental mold Aspergillus fumigatus is the primary cause of invasive aspergillosis. In patients with high-risk conditions, including stem cell and organ transplant recipients, mortality exceeds 50%. Triazole antifungals have greatly improved survival (1); however, triazole-resistant A.

Transmission of Balamuthia mandrillaris by Organ Transplantation.

Background: During 2009 and 2010, 2 clusters of organ transplant-transmitted Balamuthia mandrillaris, a free-living ameba, were detected by recognition of severe unexpected illness in multiple recipients from the same donor.

Methods: We investigated all recipients and the 2 donors through interview, medical record review, and testing of available specimens retrospectively. Surviving recipients were tested and treated prospectively.

Fatal transplant-associated west nile virus encephalitis and public health investigation-california, 2010.

Background: In December 2010, a case of West Nile virus (WNV) encephalitis occurring in a kidney recipient shortly after organ transplantation was identified.

Methods: A public health investigation was initiated to determine the likely route of transmission, detect potential WNV infections among recipients from the same organ donor, and remove any potentially infected blood products or tissues. Available serum, cerebrospinal fluid, and urine samples from the organ donor and recipients were tested for WNV infection by nucleic acid testing and serology.

Outbreak of Marburg hemorrhagic fever among miners in Kamwenge and Ibanda Districts, Uganda, 2007.

Marburg hemorrhagic fever was detected among 4 miners in Ibanda District, Uganda, from June through September, 2007. Infection was likely acquired through exposure to bats or bat secretions in a mine in Kamwenge District, Uganda, and possibly human-to-human transmission between some patients. We describe the epidemiologic investigation and the health education response.

Filovirus outbreak detection and surveillance: lessons from Bundibugyo.

The first outbreak of Ebola hemorrhagic fever (EHF) due to Bundibugyo ebolavirus occurred in Uganda from August to December 2007. During outbreak response and assessment, we identified 131 EHF cases (44 suspect, 31 probable, and 56 confirmed). Consistent with previous large filovirus outbreaks, a long temporal lag (approximately 3 months) occurred between initial EHF cases and the subsequent identification of Ebola virus and outbreak response, which allowed for prolonged person-to-person transmission of the virus.

Proportion of deaths and clinical features in Bundibugyo Ebola virus infection, Uganda.

The first known Ebola hemorrhagic fever (EHF) outbreak caused by Bundibugyo Ebola virus occurred in Bundibugyo District, Uganda, in 2007. Fifty-six cases of EHF were laboratory confirmed. Although signs and symptoms were largely nonspecific and similar to those of EHF outbreaks caused by Zaire and Sudan Ebola viruses, proportion of deaths among those infected was lower (≈40%).

An investigation of a major outbreak of Rift Valley fever in Kenya: 2006-2007.

An outbreak of Rift Valley fever (RVF) occurred in Kenya during November 2006 through March 2007. We characterized the magnitude of the outbreak through disease surveillance and serosurveys, and investigated contributing factors to enhance strategies for forecasting to prevent or minimize the impact of future outbreaks. Of 700 suspected cases, 392 met probable or confirmed case definitions; demographic data were available for 340 (87%), including 90 (26.

Household-based sero-epidemiologic survey after a yellow fever epidemic, Sudan, 2005.

From September through early December 2005, an outbreak of yellow fever (YF) occurred in South Kordofan, Sudan, resulting in a mass YF vaccination campaign. In late December 2005, we conducted a serosurvey to assess YF vaccine coverage and to better define the epidemiology of the outbreak in an index village. Of 552 persons enrolled, 95% reported recent YF vaccination, and 25% reported febrile illness during the outbreak period: 13% reported YF-like illness, 4% reported severe YF-like illness, and 12% reported chikungunya-like illness.

Domestically acquired seoul virus causing hemorrhagic fever with renal syndrome-Maryland, 2008.

Hantaviruses are rodent-borne viruses capable of causing human disease. The Seoul virus is a hantavirus that causes hemorrhagic fever with renal syndrome in East Asia. To our knowledge, we report the first domestically acquired case of hemorrhagic fever with renal syndrome caused by the Seoul virus, confirmed by serology testing, reverse-transcriptase polymerase chain reaction, and nucleotide sequence analysis.

Successful immunization of an allogeneic bone marrow transplant recipient with live, attenuated yellow Fever vaccine.

Vaccination against yellow fever is effective, but available live virus vaccines are not recommended for use in immunocompromised or elderly patients. We report the successful and uneventful immunization of a 62-year-old man with a history of allogeneic bone marrow transplant and discuss evidence for this recommendation.

An outbreak of yellow fever with concurrent chikungunya virus transmission in South Kordofan, Sudan, 2005.

From September through December 2005, an outbreak of hemorrhagic fever occurred in South Kordofan, Sudan. Initial laboratory test results identified IgM antibodies against yellow fever (YF) virus in patient samples, and a YF outbreak was declared on 14 November. To control the outbreak, a YF mass vaccination campaign was conducted and vector control implemented in parts of South Kordofan.

Lack of evidence of avian-to-human transmission of avian influenza A (H5N1) virus among poultry workers, Kano, Nigeria, 2006.

Background: In February 2006, poultry outbreaks of highly pathogenic avian influenza A (H5N1) virus were confirmed in Nigeria. A serosurvey was conducted to assess H5N1 transmission among poultry workers and laboratory workers in Nigeria.

Methods: From 21 March through 3 April 2006, 295 poultry workers and 25 laboratory workers with suspected exposure to H5N1 virus were administered a questionnaire to assess H5N1 exposures, medical history, and health care utilization.
