Influenza is an acute viral respiratory infection that affects all age groups and is associated with high mortality during pandemics, epidemics, and sporadic outbreaks. Nearly 10% of the world's population is affected by influenza annually, with about half a million deaths each year. Influenza ...
Influenza A virus (IAV) and Streptococcus pneumoniae (S. pn.) are major causes of respiratory tract infections, particularly during co-infection. The synergism between these two pathogens is characterized by a complex network of dysregulated immune responses, some of which last until recovery post ...
Influenza-like illness (ILI) and severe acute respiratory infection (sARI) were identified by follow-up calls twice a week. For those identified, influenza and respiratory syncytical virus (RSV) were tested by point-of-care test kits. We calculated overall and stratified (by trimester or age ...
(-).Routine blood test:WBC:7.9 × 10-9 /L,N:5.5×10-9 /L,L:19.5%.Chest X-ray examination:more double lung markings,increased heart shadow.Seasonal A /influenza B virus detection(colloidal gold method)were negative.H1N1 influenza virus was detected and isolated from throat swab by RT-...
Targeted surveillance for influenza A(H7N9) identified 24 cases of infection with this virus in Guangzhou, China, during April 1, 2013-March 7, 2014. The spectrum of illness ranged from severe pneumonia to asymptomatic infection. Epidemiologic findings for 2 family clusters of infection highlight ...
Furthermore, inactivated influenza virus vaccines focus on the induction of systemic IgG responses but do not effectively induce mucosal IgA responses. Here, I review the differences between natural infection and vaccination in terms of the antibody responses they induce and how these responses protect...
Figure 1. Influenza A virus (IAV) infection and dynamics. (a) Description of the main phases of IAV infection within a host. After entering the respiratory tract, each virion binds to a target cell. Then, virions enter the eclipse phase (5–12 hpi), before starting to replicate and infe...
Viral infections have been suggested to be one of the environmental factors associated with the development of this disorder. We comprehensively review all relevant published literature focusing on the relationship between schizophrenia and various viral infections, such as influenza virus, herpes virus 1...
mRNA vaccines have elicited potent immunity against infectious disease targets in animal models of influenza virus, Zika virus, rabies virus and others, especially in recent years, using lipid-encapsulated or naked forms of sequence-optimized mRNA. Diverse approaches to mRNA cancer vaccines, including ...
Human infection with the wild influenza A H6 subtype has not been reported in the scientific literature. In our study, we detected a human case of infection with the H6N1 virus. We report the clinical presentation, contact and environmental investigations of the infected patient, and assess the ...
