China reports new tick-borne virus ALTNV linked to flu-like illness

Beijing researchers identify ALTNV, a newly discovered tick-borne nairovirus in China, which can cause flu-like symptoms, fatigue, gastrointestinal issues and reduced platelets. In a study of 3,163 tick-bitten patients, ALTNV appeared in about 10% and co-infection with Dabie bandavirus (DBV) was associated with respiratory and kidney problems, with 7 deaths among those co-infected. There is no specific antiviral treatment for ALTNV, so care is supportive and tick-bite prevention is critical. ALTNV has not been reported in the U.S., and the findings in the New England Journal of Medicine underscore the need for differential diagnosis in regions where tick-borne diseases are endemic.

Beijing researchers identify ALTNV, a new tick-borne virus causing flu-like illness

Beijing researchers identified Asian longhorned tick nairovirus (ALTNV), a new orthonairovirus transmitted by ticks that causes an influenza-like illness with fever, fatigue, GI symptoms, and abnormal liver tests. In a study of 3,163 patients, ALTNV was found in 10.4% of DBV-negative patients (15.1% among those negative for Dabie bandavirus), often presenting with fatigue, GI problems, thrombocytopenia, and elevated aminotransferases; coinfection with DBV was linked to more respiratory symptoms and kidney impairment, with 7 deaths in coinfected cases. ALTNV RNA was detected in 1.3% of ticks, especially Haemaphysalis longicornis, which can transmit the virus to mice. The virus is genetically distinct among orthonairoviruses and underscores the need for differential diagnosis in regions where SFTS is endemic.

Wisconsin Reports Fatalities and Hospitalizations from Tick-Borne Powassan Virus

A rare tick-borne virus called Powassan has caused one death and hospitalized two in Wisconsin this year, with cases increasing nationwide. The virus is transmitted by black-legged ticks, which also carry Lyme disease, and symptoms can range from none to severe brain inflammation. Health officials emphasize the importance of protecting against tick bites, especially during peak activity months from April to September.

Deadly Congo Fever Outbreak Hits Namibia, Claims Life

Namibia is facing an outbreak of Crimean-Congo haemorrhagic fever (CCHF), one of the world's deadliest diseases, after a man died from the tick-borne virus. CCHF has a mortality rate of up to 40%, similar to that of Ebola and Marburg, and can spread between humans through bodily fluids or among hospital patients if medical equipment is not properly sterilized. The WHO has identified CCHF among its nine 'priority' diseases that pose the biggest risk to public health due to a lack of treatments or their ability to cause a pandemic.

Namibia reports fatal outbreak of Congo fever.

Namibia has declared an outbreak of Crimean-Congo haemorrhagic fever (CCHF) after one person died of the disease in the capital Windhoek. CCHF is a tick-borne virus that can also transmit between humans by close contact with blood or bodily fluids. It has a fatality rate of between 10% and 40%. The government has activated health emergency committees to prevent further transmission and is closely monitoring all contacts of the deceased in Gobabis and Windhoek.
