The purpose of this study is to find out how, why, and when Rift Valley Fever (RVF) spreads. Participants will be 250 adults and children, aged 1 year and older, from the Ijara District, Kenya. They will be given a questionnaire, undergo a medical examination that includes an eye exam, and have a 1-teaspoon sample of blood taken from a vein. Participation will take about 3 hours.
This study is to determine if a vaccine for Rift Valley Fever (RVF) is safe to give to humans. Rift Valley Fever is a disease carried by mosquitoes that can infect both animals and humans. The study will also examine how well the vaccine (RVF MP-12) stimulates the body's immune response (which fights off infection) and if the vaccine is stable or if the virus used to make the vaccine changes into a different form once injected into the body. Twenty healthy volunteers (18-50 yea...
This study is designed to determine the safety and immunogenicity of an inactivated Rift Valley Fever (RVF) Vaccine in adults

This is a Phase IV randomized, double-blinded, placebo-controlled study in 1000 individuals aged 18 years or older, with community acquired pneumonia (CAP) who meet all eligibility criteria in endemic regions. This study is designed to provide data on the effectiveness of early antifungal treatment (Fluconazole, 400 mg/day) for coccidioidomycosis pneumonia (also referred to as Valley Fever (VF) Pneumonia or acute onset valley fever) vs. placebo in subjects with coccidioidomycos...
The soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) was an established biomarker useful for infection in non-neutropenic patients. In this study, we tested sTREM-1 in the patients with neutropenic fever. Pro-calcitonin (PCT) and C-reactive protein (CRP) were also measured. We planned to investigate and explore the role of sTREM-1 in early diagnosis of infection in patients with neutropenic fever.
Mosquito-borne diseases continue to cause significant morbidity and mortality worldwide despite on-going control efforts. In 2015, there were >200 million cases of malaria worldwide, causing nearly half a million deaths, with most of the deaths occurring among children under the age of 5 years 1. Mosquitos also transmit arboviruses, including dengue, yellow fever, West Nile virus, chikungunya, Rift Valley fever, Japanese encephalitis, and Zika virus. The current new outbreak of...
Originally test host's to understand the tracking healthily and immune change of the dengue fever in Taiwan. Blood drawing 20 c.c for liver examination, kidney and other biochemical function, analyze host immunity adjusts and controls the gene, and the reciprocation that may be produced with the virus hepatitis, besides collected 10 c.c urine at the same time. Urine check is in order to compare acute infect and infected over three month person, the change of chemical compositio...
The Zika infection is a viral disease that is transmitted to humans by the same mosquito that transmits Dengue and Chikungunya fever. The Zika virus has been found in various body fluids such as urine, blood and semen, but we do not know how long it persists in these fluids. For example, parts of the virus were reported to persist in semen after six months of the onset of symptoms, but we do not know if the virus can stay longer. In this way, we want to investigate how long the...
The objective of this study is to study immune memory generated against the yellow fever vaccine (YFV) in participants who recently received the YFV vaccine. Volunteers who are planning to travel to yellow fever endemic areas will be recruited into this study. Volunteers will receive the yellow fever vaccine at the Hope Clinic of Emory University or at their private health care provider's office. Blood tests will be drawn before the vaccination and at 3 visits following vacc...
Dengue virus is an arbovirus transmitted by mosquitoes which causes significant morbidity and mortality among children in tropical regions, especially in resource limited countries. The objective of this protocol is to compare the sensitivity and specificity of clinical gestalt and two rapid antigen tests for dengue virus and to compare the gene expression of leukocytes in distinct dengue fever disease phenotypes module-based RNA microarray technology.
West Nile (WN) virus infection is an emerging disease. Infection with WN virus may lead to paralysis, coma, and death. The purpose of this study is to determine the safety of and immune response to a two-dose regimen of a WN vaccine in healthy adults. The vaccine is based on a live attenuated vaccine developed against dengue virus.
The investigators at Rockefeller University are doing this research to study how the immune system responds to viruses and other infectious agents by using the yellow fever 17D vaccine as a model. The YFV-17D vaccine is one of the safest and most effective vaccines known and has been used to vaccinate humans against yellow fever virus (YFV) infection since the 1930s. By studying how the human immune system responds to the YFV vaccine we hope to learn more about the normal funct...
Dengue fever, which is caused by dengue viruses, is a major health problem in subtropical regions of the world. There are four different forms (serotypes) of dengue virus that can cause dengue fever. The purpose of this study is to determine the safety and immune response to a vaccine containing a particular dengue serotype when an individual has been previously vaccinated with a different dengue serotype.
The purpose of this study is to investigate the mechanism of a successful immune response to hepatitis C virus (HCV) infection. Currently, it is believed that the immune system is involved in responding to HCV infection, but how it is involved is not known. It is estimated that 30% of individuals infected with HCV are able to clear the virus without treatment, while 70% progress to chronic infectious. By studying the immune responses in these two populations, we, the research...
Dengue infection has been identified as the fastest spreading mosquito-borne viral disease by World Health Organization (WHO), which affects more than 2.5 billion people living in the subtropical and tropical regions. Malaysia is hyper-endemic with all four dengue virus serotypes circulating and responsible for the escalating number of cases over the years. As of 28 February 2015, there are 62 deaths secondary to dengue infection being reported in Malaysia; and the total number...
The IHU Mediterranean infection is national reference centre for Q fever. Coxiella burnetii is the bacteria responsible of this infection. The bacterium Coxiella burnetii infection is associated with secretion by the body both many antibodies against the bacteria but also against certain cells of the body (autoantibodies). These autoantibodies may have no effect or be associated with specific symptoms. Anti-Phospholipid antibodies are especially prevalent in the Q fever. Apart ...
In normal people, the Epstein-Barr (EB) virus infection causes a flu like illness (sometimes called infectious mononucleosis or glandular fever or kissing disease) and usually gets better when the immune system controls the infection. The virus, however, remains hidden in the body for life. After a transplant, while the new immune system is growing back, the EB virus can come out and infect cells and cause them to grow in an uncontrolled manner. Patients can develop fevers, swo...
This study will determine if an experimental vaccine to prevent Ebola virus infection is safe and what side effects, if any, it causes. Ebola virus infection may range from mild to severe, and may cause breathing problems, severe bleeding, kidney problems and shock that can lead to death. The vaccine used in this study contains man-made genetic material similar to one part of the Ebola virus, which is designed to stimulate an immune response to the virus. The vaccine itself can...
West Nile (WN) virus infection is an emerging disease; WN infection may lead to paralysis, coma, and death. The purpose of this study is to test the safety of and immune response to a WN vaccine in healthy adults. The vaccine is based on a live attenuated vaccine developed against dengue virus.
Rationale and Aims: Infection by dengue virus (DENV) causes major morbidity and mortality throughout the world. In 2012, an estimated 3.6 billion people live in areas at risk for DENV infection, including Singapore. The key pathology of DENV infection is vascular leakage, which can occur in mild cases and can become life-threatening in severe cases when patients may develop dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Mast cells (MCs) are strongly activated by...
