1 day ago · Typhoid fever, caused by the bacterium Salmonella enterica Serovar Typhi.  In Canada alone, the typhus epidemic of 1847 killed more than 20,000 people from 1847 to 1848, mainly Irish immigrants in fever sheds and other forms of quarantine, who had contracted the disease aboard the crowded coffin ships in fleeing the Great Irish Famine .
3 days ago · Lassa fever, also known as Lassa hemorrhagic fever (LHF), is a type of viral hemorrhagic fever caused by the Lassa virus. Many of those infected by the virus do not develop symptoms. When symptoms occur they typically include fever, weakness, headaches, vomiting, and muscle pains.
6 days ago · These diseases can be spread while bathing, washing, drinking water, or by eating food exposed to contaminated water. While diarrhea and vomiting are the most commonly reported symptoms of waterborne illness, other symptoms can include skin, ear, respiratory, or eye problems.

An asymptomatic carrier is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms. Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, HIV, C. difficile, influenzas, cholera, tuberculosis and COVID-19, although the latter is often associated with "robust T-cell imm
Asymptomatic carriers can be categorized by their current disease state. When an individual transmits pathogens immediately following infection but prior to developing symptoms, they are known as an incubatory carrier. Humans are also capable of spreading disease following a period of illness. Typically thinking themselves cured of the disease, these individuals are known as convalescent carriers. Viral diseases such as hepatitis and poliomyelitis are frequently transmitted in this manner. "Heal
The limited information on the prevalence of asymptomatic carriers creates a considerable difficulty when planning public health initiatives. Given that disease surveillance is dependent on estimates for both the asymptomatic rates and symptomatic rates of disease, the lack of information on the prevalence of carriers can lead to insufficient initiatives for the mitigation of common public health concerns such as C. difficile or influenza. Researchers have expressed the desire to better predict
While an exact explanation for asymptomatic carriage is unknown, researchers have been dedicating their efforts towards understanding how specific bacteria thrive in human hosts in the hopes of determining a universal understanding of asymptomatic transmission.
Asymptomatic bacteriuria is a condition that typically impacts 3–5% of women, with the most vulnerable populations being the elderly and those diagnosed with diabetes. Within the female population, the risk of bacteriuria increases with age. Escherichia coli is the most common organism found during urine analysis, though the variety of potentially infectious organisms is diverse and can include Enterobacteriaceae, Pseudomonas aeruginosa, Enterococcus species, and group B streptococcus ...
Asymptomatic carriers have furthered the spread of many infectious diseases. A common principle in epidemiology, the 80–20 rule, speculates that 80% of the disease transmission is conducted by only 20% of people in a population.

4 days ago · Marked fever, ‘stepwise’ (rising through each day with progressive peaks) in <20%. Abdominal pain, relative bradycardia (Faget’s sign), cough, constipation. Rose spots in ~25% (salmon-coloured, 1–4cm, blanching, due to bacterial emboli to dermis). Diarrhoea (‘pea-soup’) and hepatosplenomegaly in 2nd week.
