Just Like COVID, Bird Flu Virus Is Also Mutating

Alert! Bird flu or the avian influenza virus is mutating. Read on to know everything.

Amid rising fears about a possible fifth wave of COVID-19 in India, experts have warned about the massive spread of Bird Flu virus in the country. In the latest report issued by the health officials of India, the government has sounded alert in Bihar after several cases of H5N1 virus were confirmed in the state. What is more concerning at the moment are the new mutations which experts have noticed in the virus. Let’s understand how threatful are these new mutations in the virus, and where India stands when it comes to facing an outbreak of the H3N1 virus or the bird flu virus.

New Mutation In Bird Flu Virus Shows High Potential For Humans Outbreak

Bird flu is an air-borne infection caused by strains of the influenza virus that primarily infect birds. The mode of transmission of this virus is via infected body fluids of the birds. The virus mainly affects the avian community of the environment. What about the humans? Although experts had shown cases of human transmission of the H3N1 0r H2N3 virus and the possibility of it entering and evading the immune system, the chances of it causing severe outcomes for humans were too low. But this is not the case anymore. A recent study has revealed something unusual and new. According to the scientists, they have identified new mutations in the avian influenza virus H5N1, which recently infected a man in Chile, and may pose a risk of spreading in humans.

According to the European Centre for Disease Control (ECDC), the risk of spread from human to human remains low but the new changes seen are ‘concerning’. It also suggests that the potential risk of human spillover is increasing.

Last month in a statement, Chile’s Health Ministry confirmed that a 53-year-old man has tested positive for the H5N1 virus. As per the medical reports, the man was reported to be in serious but stable condition with a severe pneumonia-like condition.

China Reports First Bird Flu Death

This comes a few days after Chin confirmed the first human death by the Bird Flu virus. The World Health Organisation (WHO) confirmed the death of a 56-year-old Chinese woman due to the H3N8 bird flu strain that is rare in humans. The H3N8 subtype of avian influenza is a rare strain of the virus and it is unusual to spread among the human community.

Talking about this rare case of bird flu death in China, the WHO confirmed that the virus responsible for the infection was influenza A(H3), which is very common in birds and extremely rare for humans. As per the global health body, there were no additional cases reported among people who had been in close contact with the infected individual.

Avian Influenza: Can This Bird Virus Turn Into a Human Virus

The virus responsible for severe human infections has been identified as H7N9 and H5N1. The symptoms that are commonly reported by the patients are like the common flu, such as fever, body aches, sore – throat, and cough. Speaking to the media, Richard J. Webby, a bird flu expert at St. Jude Children’s Research Hospital stated that to become threatful to the human community the H5 virus will have to undergo three major categories of changes. “The sequences from the person in Chile have one of those classes of changes. But we also know that of those three sets of changes, this is the easiest one for the virus to make,” Jude was quoted as saying.

How to detect the H3N1 virus infection in humans? Bird flu infection is usually diagnosed by collecting a swab from the upper respiratory tract of the sick person. “The disease can carry high mortality in humans. Some antiviral drugs, if taken within two days of symptoms, may help. Oseltamivir or Tamiflu is one of the drugs effective against bird flu,” said Dr Nitin Verma Director Pediatrics Rosewalk Healthcare.

Bird Flu Outbreak: How Big Is The Threat For India?

As the speculations of the H5 virus turning into a human virus from a bird virus is on the rise in India, we spoke to Dr Anamika Dubey, Senior Consultant, General Paediatrician, Madhukar Rainbow Children’s Hospital, Malviya Nagar.

Dr Dubey said, “In the United States, there are repeated outbreaks of H5 N1 in wild birds and poultry since 2022. In India H5N1 in poultry farms was first reported in 2006 in Maharashtra. Since then outbreaks of Avian influenza A in poultry farms is reported every year. One human case of H5n1 was notified on 21 July 2021 from Haryana state.”

Talking about the safety measures that one can take during a bird flu outbreak, Dr Dubey said, “As advised by WHO, at all times the public should avoid contact with high-risk environments such as live animal markets/farms and live poultry, or surfaces that might be contaminated by poultry or bird faeces. Hand hygiene with frequent hand washing with soap and water is recommended. Good food safety practices should be followed. There is no evidence to suggest that Influenza a or other avian influenza viruses can be transmitted to humans through properly cooked poultry. There is no epidemiological evidence to suggest that people have been infected with avian influenza virus by consumption of eggs or egg products. However, eggs from areas with outbreaks in poultry should not be consumed raw or partially cooked.”

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
