Legionella Outbreak In Argentina The Cause Of 11 ‘Mysterious Pneumonia’ Cases, 4 Deaths – Forbes

Published

 on


The mysterious pneumonia outbreak in Tucuman, Argentina, that I covered for Forbes yesterday, is not so mysterious any more. According to an update from the Pan American Health Organization (PAHO), the Argentina Ministry of Health has confirmed that Legionella bacteria is the cause of the outbreak that has now left 11 people ill and four dead.

Here’s a PAHO tweet with the update:

The update specifically mentioned Legionella pneumophila, which is one of a legion of different Legionella bacteria species that also includes L. longbeachae, L. feeleii, L. micdadei, and L. anisa. Legionella can hang out in amoebae that live in wet environments such as air conditioning systems, cooling towers, hot tubs, plumbing systems, humidifiers, ice-making machines, fountains, misting systems, whirlpool spas, ventilators, potting mixes, and composts. This is yet another reason why you shouldn’t shove potting mix or compost up your nose.

When the bacteria enters your lungs via your inhaling contaminated water droplets or soil, the result can be a milder illness called Pontiac Fever with symptoms developing a few hours to 3 days after exposure to the bacteria. Or a more severe illness, dubbed Legionnaire’s Disease, with symptoms developing two to 10 days after exposure. The severity of the illnesses in this outbreak suggests that it’s been an outbreak of Legionnaire’s Disease. It’s called Legionnaire’s Disease not because it will turn you into a Legionnaire and wear those hats that they wear. Instead, as I described for Forbes in 2018, it got its name from where the bacteria was first identified: at a three-day American Legion convention at the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, in 1976.

Not everyone exposed to the Legionella bacteria will end up getting ill. You are more likely to develop Legionnaire’s Disease if you have a weaker immune system (e.g., 50 years or older, have a chronic disease, or are on medications that suppress the immune system) or weaker lungs (e.g., suffering chronic obstructive pulmonary disease). That doesn’t mean that you should say, “bring it on,” to Legionella bacteria. Even if you are perfectly healthy, you can still get Legionnaire’s Disease, although the likelihood would be significantly less.

The key to treating Legionnaires’ disease is getting the right antibiotics as soon as possible. As the World Health Organization (WHO) relates, the overall death rate from Legionnaires’ disease is between 5 and 10%. However, this death rate can bounce up to 5 to 30% if you have a weaker immune system and even further up to 40 to 80% if you have don’t get proper treatment in time. That’s why doctors should look for evidence of Legionella in your urine, blood, or sputum as soon as should as Legionnaires’ disease is in any way suspected.

So the good news about this pneumonia outbreak in Tucuman, Argentina, is that it isn’t a oh-my-goodness-what-the-heck-is-going-on outbreak. Instead, it’s a oh-this-has-happened-before-such-as-in-Philadelphia-in-1976 outbreak. It also isn’t common for an infected person to transmit Legionella to another person, although there has been a documented case of that happening in the past. Therefore, the chances of Legionella spreading wildly in the population is very, very low. This certainly isn’t a situation where you should panic and start hoarding toilet paper. (In general, it’s unlikely that health authorities will ever say, “OK, everyone hoard toilet paper now.”) This Legionella outbreak is not the same as the Covid-19 pandemic situation. Or the monkeypox outbreak situation. In other words, this Legionella outbreak is not likely to spread far and wide.

That being said, authorities aren’t going to say something like YOLO and not continue to act with urgency. Now, they are trying to identify the source of the outbreak as soon as possible to prevent further people from getting sick. After all, you don’t want some water system to keep spraying Legionella into the air like a mist machine at a Phantom of the Opera show. The Argentina Ministry of Health and local health authorities have been collecting environmental samples in and around the private clinic in San Miguel de Tucumán in northwestern Argentina where the health care workers affected by the outbreak worked. This may help identify what needs a-fixing. They’ll want to make sure that there’s no more “airing” on the side of the Legionella bacteria.

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.
