We decided to update and amalgamate our reviews on the antiviral drugs zanamivir and oseltamivir for influenza on the basis of the manufacturers' reports to regulators (called clinical study reports) and regulators' comments (which we called regulatory information). Clinical study reports are extensive documents with exhaustive details of the trial ...

Influenza is a viral respiratory infection that causes an acute febrile illness with myalgia, headache and cough, and can result in high morbidity and mortality rates during an epidemic. Annual epidemics are thought to result in between three and five million cases of severe influenza and between 250,000 and 500,000 deaths worldwide. Currently, annual ...

Children (< 16 years old) and the elderly (above 65 years old) are the two age groups that appear to have the most complications following an influenza infection. Influenza has a viral origin and often results in an acute respiratory illness affecting the lower or upper parts of the respiratory tract, or both. Viruses are mainly of two subtypes (A ...

Childhood vaccinations provide an effective method of protection against diseases. The World Health Organization (WHO) recommends that routine infant immunisation programmes include a vaccination against Haemophilus influenzae (H. influenza) type B (HIB) in the combined diphtheria-tetanus-pertussis (DTP)-hepatitis B virus (HBV) vaccination. We compared ...

Influenza (true 'flu) is an infection of the airways caused by the Influenza group of viruses. Influenza occurs most commonly during winter months and can result in symptoms such as fever, cough, sore throat, headache, muscle aches and fatigue. These are usually self limiting but may persist for one to two weeks. The most common complications of influenza ...

Influenza is a respiratory infection in which cough, runny nose, headache and fever are frequent manifestations. Most symptoms resolve without treatment within three to seven days. However, hospitalisation, pneumonia and even death may occur as rare complications of the illness, especially among children and the elderly. Pandemics are also a reason ...

Cystic fibrosis is a genetic, life-threatening disorder affecting multiple organs. People with cystic fibrosis have a higher risk of chronic lung disease. Influenza can worsen the course of the disease in cystic fibrosis by increasing the risk of pneumonia and secondary respiratory complications. During a pandemic, flu symptoms may be more severe and ...

People with cystic fibrosis have blocked airways which results in frequent airway infections. Infections with viral diseases like influenza ("the flu") can worsen lung damage. Doctors therefore often advise people with cystic fibrosis to be vaccinated against influenza every year. We searched for studies which compared different vaccines or compared ...

Although respiratory viruses usually only cause minor disease, they can cause epidemics. Approximately 10% to 15% of people worldwide contract influenza annually, with attack rates as high as 50% during major epidemics. Global pandemic viral infections have been devastating. In 2003 the severe acute respiratory syndrome (SARS) epidemic affected around ...
