1. Dynamics of Coinfection : Complexity and Implications
Sammanfattning : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. LÄS MER
2. HIV-2 genetic evolution and viral dynamics
Sammanfattning : HIV-2 is less pathogenic and less transmissible compared to HIV-1. This is believed to be due to the lower viral load that is seen in HIV-2 infected patients. However, why this lower viral load is seen is not known. In this thesis we have investigated different aspects of HIV-2 in order to understand the pathogenesis of HIV-2 better. LÄS MER
3. Imported infections’ importance : global change driving Dengue dynamics
Sammanfattning : Background Dengue is a significant problem of international health concern. According to the World Health Organization in 2012, globally, dengue is “the most important mosquito borne viral disease” with incidence 30 higher than it had been 50 years ago. LÄS MER
4. Epidemiology of viral respiratory infections with focus on in-hospital influenza transmission
Sammanfattning : Human Rhinoviruses (HRV) and influenza viruses are respiratory pathogens which represent a major global disease burden. Healthcare-associated infections (HCAI) are increasingly recognized as a public health concern, but limited data has been published on the characteristics and epidemiology of HCAI caused by respiratory viruses.

5. Viral Loop Dynamics in Temperate and Polar Freshwaters
Sammanfattning : All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. LÄS MER
