TWO TYPES OF STRAINS OF TYPHUS VIRUS ARE OBSERVED IN MEXICO: first the murine type which is obtained from wild rats in nature, from isolated endemic cases, and from cases during short epidemic outbreaks, and second, the epidemic type of strains which is obtained from long standing serious epidemics. Some of these epidemic strains correspond entirely to strains of historic Old World typhus. Othe...

Background and aims: Since accurate forecasts help inform decisions for preventive health-careintervention and epidemic control, this goal can only be achieved by making use of appropriatetechniques and methodologies. As much as forecast precision is important, methods and modelselection procedures are critical to forecast precision. This study aimed at providing an overview o...

Consequently when there is no urgent work at headquarters, a tour is, so to speak, indicated. Branch hospitals must be inspected, outbreaks of epidemic disease investigated and, if possible, stamped out, registration of vital statistics enquired into, and the work of the vaccinators tested to prevent fraud. It is so very easy to successfully vaccinate a number of imaginary children, that not in...

Bristol has always seemed to me to typify in her professional classes, her business men, and in her social endeavour that combine of solid worth, steady, unfaltering grip, whether in good times or bad, and unheralded point to point attainment, which is summed up in that great word England. We may not wholly agree with Thomas Carlyle that " The English are a dumb people. They can do great acts b...

The present article provides a concise historical review on classical epidemic typhus (exanthemata typhus) in the world as well its outbreaks in Iran mainly during the 19th and 20th centuries. Typhus is still a potential public health threat under certain conditions, despite the fact that nowadays, efficient antibiotics are accessible and sanitary conditions which lead to typhus outbreaks have ...

An unusually large outbreak of conjunctivitis caused by adenovirus type 4 involved 113 proved cases during a 7-month period. Though the disease was less severe than is commonly seen in epidemic keratoconjunctivitis caused by other serotypes, the cornea was affected in 23% of cases and symptoms persisted for at least 5 weeks in 6 patients. A concurrent increase in nonocular adenovirus type 4 inf...

In 2011, porcine epidemic diarrhea virus (PEDV) infection rates rose substantially in vaccinated swine herds. To determine the distribution profile of PEDV outbreak strains, we sequenced the full-length spike gene from samples from 9 farms where animals exhibited severe diarrhea and mortality rates were high. Three new PEDV variants were identified.

Porcine epidemic diarrhea virus (PEDV) could cause an acute and highly contagious enteric disease in swine. Here, we report the complete genome sequence of PEDV strain CH/HNZZ47/2016 isolated from suckling piglets with mild diarrhea in Henan Province, China. It will help understand the molecular and evolutionary characteristics of PEDV in China.

After porcine epidemic diarrhea virus (PEDV) was detected in the United States in 2013, we tested environmental samples from trailers in which pigs had been transported. PEDV was found in 5.2% of trailers not contaminated at arrival, , suggesting that the transport process is a source of transmission if adequate hygiene measures are not implemented.
