Newborns with a mother who was potentially exposed and who have positive blood tests, microcephaly or intracranial calcifications  should have further testing including a thorough physical investigation for neurologic abnormalities, dysmorphic features, splenomegaly, hepatomegaly, and rash or other skin lesions. Other recommended tests are cranial ultrasound, hearing evaluation, and eye examination. Testing should be done for any abnormalities encountered as well as for other congenital infections such as syphilis, toxoplasmosis, rubella, cytomegalovirus infection, lymphocytic choriomeningitis virus infection, and herpes simplex virus. Some tests should be repeated up to 6 months later as there can be delayed effects, particularly with hearing. Infant feeding in areas of Zika virus transmission
In response to the widespread transmission of Zika virus during the 2016 outbreak and concerns of viral genetic material detected in breast milk the World Health Organization (WHO) released a Guideline of infant feeding in areas of Zika virus transmission, first in 2016 and updated in 2021, where the evidence showed that despite the detection of Zika virus in breast milk, there is unclear evidence of transmission to the infant, and considering that Zika virus infection among infants is mild, the balance between desirable and undesirable effects favours breastfeeding versus not breastfeeding. According to the 2021WHO guidelines:
Infants born to mothers with suspected, probable or confirmed Zika virus infection or who reside in or have travelled to areas of ongoing Zika virus transmission should be fed according to normal infant feeding guidelines.
Brucellosis ring testing of milk and cream, and testing of cattle to be slaughtered ended on 1 April 1999. Monitoring continues through testing at auction markets, through standard disease-reporting procedures, and through  testing of cattle being qualified for export to countries other than the United States. China
An outbreak infecting humans took place in Lanzhou in 2020 after the Lanzhou Biopharmaceutical Plant, which was involved in vaccine production, accidentally pumped out the bacteria into the atmosphere in exhaust air due to use of expired disinfectant. The outbreak affected over 6,000 people. Europe
Malta
Until the early 20th century, the disease was endemic in Malta to the point of it being referred to as "Maltese fever". Since 2005, due to a strict regimen of certification of milk animals and widespread use of pasteurization, the illness has been eradicated from Malta. Republic of Ireland
Ireland was declared free of brucellosis on 1 July 2009. The disease had troubled the countrys farmers and veterinarians for several decades. The Irish government submitted an application to the European Commission, which verified that Ireland had been liberated. Brendan Smith, Irelands then Minister for Agriculture, Food and the Marine, said the elimination of brucellosis was "a landmark in the history of disease eradication in Ireland". Irelands Department of Agriculture, Food and the Marine intends to reduce its brucellosis eradication programme now that eradication has been confirmed. UK
Mainland Britain has been free of brucellosis since 1979, although there have been episodic re-introductions since.
