Between 2014 and 2016 more than 3,800 imported human cases of chikungunya fever in Florida highlight the high risk for local transmission. To examine the potential for sustained local transmission of chikungunya virus (CHIKV) in Florida we tested whether local populations of Aedes aegypti and Aedes albopictus show differences in susceptibility to infection and transmission to two emergent linea...

purpose: to report the possible transmission of zygomycetes infection by a corneal graft harvested from a donor with signs of trauma to the orbital region to a keratoconic patient who underwent deep anterior lamellar keratoplasty (dalk). case report: a 19-year-old keratoconic man underwent dalk in the right eye. the corneal graft was harvested from a donor with signs of orbital trauma. on posto...

the main objective of this study is to find the prevalence, level of knowledge, and mode of transmission of reproductive tract infection (rti)/sexually transmitted infection (sti) among evermarried females in uttar pradesh. to study the various socio-economic and demographic factors responsible for rti/sti among married females. this study is based on data extracted from district level health s...

Immunization of mice by infection or intraperitoneal injection with homotypic A(2), heterotypic A(0), or recombinant A(0)A(2) virus have differing effects on transmission of influenza A(2) virus infection. Immunization by infection with A(2) virus resulted in refractoriness to reinfection either by artificial aerosols or by exposure to infected cage-mates. Immunization by inoculation with inact...

Background: The household transmission of hepatitis B virus (HBV) is a major health problem. High incidence of HBV infection is observed within the household contacts of HBV carriers. We aimed to evaluate serological markers of hepatitis B infection among family members of HBV carriers in Arak, central Iran. Methods<stron...

In the midway of pandemic, understanding transmission dynamics for SARS CoV-2 infection is important to stop chain transmission; chances spread increased at household setting owing duration contact with an infected person, high viral load, and various sociodemographic factors, so early case identification separation close contacts help in prevention infection.

After reviewing the evidence on the relation of vertical transmission of HIV to stage of infection in the mother, I developed a stochastic model of transmission in which the probability of transmission per week is proportional to the virus load in the mother. The virus load in different stages of the infection is measured by viral RNA levels or tissue culture infectious virus levels in plasma. ...
