A potentially deadly strain of avian (bird) influenza virus appears to have transmitted between humans for the very first time.
Research published online by the British Medical Journal (BMJ)
claims that the avian influenza A (H7N9) virus which has claimed dozens
of lives in China this year, had been passed from a 60-year-old man to
his 32-year-old daughter who was caring for him at the time.
The father and daughter lived in eastern
China and the father had made frequent trips to a live poultry market.
He suddenly became ill just days following his latest visit back in
March and later died on 4 May due to multiple organ failure.
However, the man’s daughter had developed symptoms of her own just
six days after her father’s admittance into hospital and actually died
ten days before he did, on 24 April. She was in good health before
caring for her father and had apparently not been in contact with any
live poultry, which means the virus must have been passed to her from
her father. Investigations later confirmed an identical virus strain in
both patients.
Dr Peter Horby, senior clinical research fellow at the Oxford
University Clinical Research Unit in Hanoi, Vietnam, said: “The most
likely source of infection for the daughter was her father, during the
period that she cared from him whilst he was ill.”
He alleviated fears over other strains of avian flu however, noting
that avian flu has been in existence for more than a decade and that
they “have not progressed any further down the path towards a pandemic
virus”. Dr Horby also said human-to-human transmission had been minimal
for strains H5N1 and H7N7, and the swine origin flu virus H3N2v.
Up until the end of June, within China there had been in excess of
130 cases reported and 43 deaths since February. Despite Dr Horby’s
assertions, there is huge fear that the outbreak could now spread
amongst humans at a rapid rate.
According to available evidence, in the majority of instances the
effected people had previously visited live poultry farms or had come
into contact with live poultry approximately seven to 10 days prior to
the emergence of their symptoms.
Symptoms begin with a high fever, cough and a shortness of breath.
Often, the sufferer will then develop more severe illness such as
pneumonia, acute respiratory distress syndrome (ARDS), septic shock and
multi-organ failure leading to death.
Although the World Health Organization (WHO) state that no vaccine
for avian influenza A(H7N9) infections in humans is currently available,
the Centers for Disease Control and Prevention (CDC) recommends Tamiflu
(oseltamivir) for the treatment of H7N9 because many of the H7N9
viruses that have been studied are likely susceptible (sensitive) to
this medication.
It is estimated that Britain attracts around 179,000 Chinese tourists
a year, and it only takes one person carrying the virus for an outbreak
to erupt and spread between people.
Tamiflu is available today through Medical Specialists Pharmacy from as little as £21.98 per pack of 10 capsules. You can buy Tamiflu online with or without a prescription at Medical Specialists, after completing a simple online consultation.
