Tropical diseases encompass all diseases that occur solely, or principally, in the tropics. In practice, the term is often taken to refer to infectious diseases that thrive in hot, humid conditions, such as malaria, leishmaniasis, schistosomiasis, onchocerciasis, lymphatic filariasis, Chagas disease, African trypanosomiasis, and dengue.

FDA approves Vaxchora for prevention of cholera

FDA approves Vaxchora for prevention of cholera

The U.S. Food and Drug Administration today approved Vaxchora, a vaccine for the prevention of cholera caused by serogroup O1 in adults 18 through 64 years of age traveling to cholera-affected areas. Vaxchora is the only FDA-approved vaccine for the prevention of cholera. [More]
Guardian system can predict risk of dangerous diseases

Guardian system can predict risk of dangerous diseases

If an infectious disease outbreak or an attack using an agent such as anthrax were to occur in Chicago, it most likely first will be noticed in emergency rooms throughout the city. Swift identification of the cause of an incoming patients' illness could be crucial to public health and safety personnel being able to intervene in time to save lives. [More]
Addition of just two DNA bases to LdAQP1 gene helps Black Fever parasite to overcome antimonial drugs

Addition of just two DNA bases to LdAQP1 gene helps Black Fever parasite to overcome antimonial drugs

Wellcome Trust Sanger Institute scientists show how the parasite responsible for the neglected tropical disease Black Fever (visceral leishmaniasis) can become resistant to drug treatment. Studying the whole genomes of more than 200 samples of Leishmania donovani revealed that the addition of just two bases of DNA to a gene known as LdAQP1 stops the parasite from absorbing antimonial drugs.

UCSD Skaggs School of Pharmacy, Janssen R&D partner to identify new therapeutic targets for Chagas disease

UCSD Skaggs School of Pharmacy, Janssen R&D partner to identify new therapeutic targets for Chagas disease

Researchers at the Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California, San Diego have entered into a research collaboration with Janssen Research & Development, LLC, one of the Janssen Pharmaceutical Companies of Johnson & Johnson, to identify new therapeutic targets for Chagas disease, a parasitic infection that is the leading cause of heart failure in Latin America.

Treating multidrug-resistant tuberculosis with regimens may improve outcomes

Treating multidrug-resistant tuberculosis with regimens may improve outcomes

Treating multidrug-resistant tuberculosis (MDR TB) with regimens that include a greater number of drugs may improve outcomes, and baseline drug susceptibility testing (DST) could identify drugs with the greatest likelihood of success, according to a paper published this week in PLOS Medicine.

More effort needed to reduce risks of mosquito-transmitted epidemics in the U.S. and Mexico

More effort needed to reduce risks of mosquito-transmitted epidemics in the U.S. and Mexico

Despite the increasing risks of mosquito-transmitted epidemics in the United States and Mexico, policymakers in both countries have made little effort to prevent future outbreaks, according to a new policy brief by tropical-disease and science policy experts at Rice University's Baker Institute for Public Policy.

Risk of developing visceral leishmaniasis much higher in transplant patients

Risk of developing visceral leishmaniasis much higher in transplant patients

Researchers from Spain have analysed the prevalence of leishmaniasis among the population of organ transplant recipients. The findings of this study, published in the journal 'PLoS Neglected Tropical Disease', confirm that the risk of developing visceral leishmaniasis ‑the most severe form of the disease which can pose life-threatening complications‑ is more than one hundred times greater in transplant patients living in areas of disease outbreak.

Experts call on U.S. and Mexican governments to reduce risk of Chagas disease

Experts call on U.S. and Mexican governments to reduce risk of Chagas disease

Chagas disease -- the third most common parasitic infection in the world -- affects approximately 7.5 million people, mostly in Latin America. To help reduce outbreaks of this disease in their countries, the United States and Mexican governments should implement a range of programs as well as fund research for the development of Chagas vaccines and treatments, according to a new policy brief by tropical-disease and science policy experts at Rice University's Baker Institute for Public Policy.

Insect-borne diseases increase with warmer climate

Insect-borne diseases increase with warmer climate

Insects, such as mosquitoes and ticks, are responsible for transmitting a range of diseases, such as malaria, chikungunya, dengue fever, and West Nile virus. The risk of contracting such illnesses is generally only considered when booking an exotic holiday. However, experts from the Emergency Response Department at Public Health England have warned that climate change could allow such vector-borne diseases to emerge closer to home. [More]
