#USA, #Missouri Department of Health Confirmed a Case of Primary Amoebic #Meningoencephalitis {#PAM} (August 13 '25)

  JEFFERSON CITY, MO – The Missouri Department of Health and Senior Services (DHSS) is announcing case of an adult Missouri resident with a laboratory-confirmed infection of Naegleria fowleri .  Naegleria fowleri is a microscopic single-celled free-living ameba that can cause a rare deadly infection of the brain called primary amebic meningoencephalitis (PAM), also known as “brain-eating” infection. Typically, fewer than 10 people a year in the United States get PAM. The Missouri patient is currently being treated for PAM in an intensive care unit of a hospital, and currently, no additional suspected cases of PAM are being investigated in Missouri. The ameba is common and naturally present in warm freshwater such as lakes , rivers and ponds; however, PAM is extremely rare. Between 1962 and 2024, there were 167 reported cases of PAM in the United States. The source of the patient’s exposure is currently being investigated by public health officials.  While not confirmed, p...

Updated joint #FAO / #WHO / #WOAH public #health #assessment of recent #influenza #H5 virus #events in animals and people (July 28 '25)

  Key points   -- At the present time , based on available information, FAO-WHO-WOAH assess the global public health risk of influenza A(H5) viruses to be low , while the risk of infection for occupationally or frequently exposed (e.g., with backyard poultry) persons is low to moderate depending on the risk mitigation and hygiene measures in place and the local avian influenza epidemiological situation.  -- Transmission between animals continues to occur and, to date, a growing yet still limited number of human infections are being reported. Although additional human infections associated with exposure to infected animals or contaminated environments are expected to occur, the overall public health impact of such infections at a global level , at the present time, is considered minor . The assessment could change if and when additional epidemiological or virological information becomes available.  -- This risk assessment from FAO, WHO and WOAH updates the assessment ...
