(Al Jazeera) Hong Kong’s Centre for Health Protection has announced its first human case of B virus in a rare incidence of a virus being transmitted from animals to humans. The centre is urging the public to refrain from touching or feeding wild monkeys to reduce the risk of catching it.

Here is what we know about the B virus and the case in Hong Kong:

What is known about the B virus case in Hong Kong?

A 37-year-old man was reported to have been attacked and injured by monkeys at Hong Kong’s Kam Shan Country Park, also locally known as Monkey Hill, in late February. The precise nature of his injuries is not known.

A few weeks later, having become ill, the man, who otherwise had “good past health”, according to a statement published on the Hong Kong government’s website, was admitted to Yan Chai Hospital’s emergency department on March 21 with a fever and “decreased conscious level”.

On Wednesday this week, his cerebrospinal fluid specimen tested positive for the B virus at the Centre of Health Protection’s laboratory.

(ESCMID Global Congress via Eurekalert) Pet dogs and cats play an important role in the spread of antibiotic-resistant bacteria, new research be presented at the ESCMID Global Congress (formerly ECCMID) in Barcelona, Spain (27-30 April) suggests.

The study has found evidence of multidrug-resistant bacteria being passed between sick cats and dogs and their healthy owners in Portugal and the UK, raising concerns that pets can act as reservoirs of resistance and so aid in the spread of resistance to vital medicines.

Antibiotic resistance is reaching dangerously high levels around the world. Drug-resistant infections kill more than 1.2 million people a year globally and, with the figure projected to rise to 10 million by 2050 if no action is taken, the World Health Organization (WHO) classes antibiotic resistance as one of the greatest public health threats facing humanity.

“Recent research indicates that the transmission of antimicrobial resistance (AMR) bacteria between humans and animals, including pets, is crucial in maintaining resistance levels, challenging the traditional belief that humans are the main carriers of AMR bacteria in the community,” says lead researcher Juliana Menezes, of the Antibiotic Resistance Lab at the Centre of Interdisciplinary Research in Animal Health, Faculty of Veterinary Medicine, University of Lisbon.

“Understanding and addressing the transmission of AMR bacteria from pets to humans is essential for effectively combating antimicrobial resistance in both human and animal populations.”

In a historic move, Nigeria has become the first country in the world to roll out a new vaccine (called Men5CV) recommended by the World Health Organization (WHO), which protects people against five strains of the meningococcus bacteria. The vaccine and emergency vaccination activities are funded by Gavi, the Vaccine Alliance, which funds the global meningitis vaccine stockpile, and supports lower-income countries with routine vaccination against meningitis.

Nigeria is one of the 26 meningitis hyper-endemic countries of Africa, situated in the area known as the African Meningitis Belt. Last year, there was a 50% jump in annual meningitis cases reported across Africa.

In Nigeria, an outbreak of Neisseria meningitidis (meningococcus) serogroup C outbreak led to 1742 suspected meningitis cases, including 101 confirmed cases and 153 deaths in seven of 36 Nigerian states (Adamawa, Bauchi, Gombe, Jigawa, Katsina, Yobe, Zamfara) between 1 October 2023 and 11 March 2024. To quell the deadly outbreak, a vaccination campaign has been undertaken on 25--28 March 2024 to initially reach more than one million people aged 1-29 years

Meningitis is a serious infection that leads to the inflammation of the membranes (meninges) that surround and protect the brain and spinal cord. There are multiple causes of meningitis, including viral, bacterial, fungal and parasitic pathogens. Symptoms often include headache, fever and stiff neck. Bacterial meningitis is the most serious, can also result in septicaemia (blood poisoning), and can seriously disable or kill within 24 hours those that contract it.

“Meningitis is an old and deadly foe, but this new vaccine holds the potential to change the trajectory of the disease, preventing future outbreaks and saving many lives,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “Nigeria’s rollout brings us one step closer to our goal to eliminate meningitis by 2030.”
