Hanta Virus Not a Global Pandemic Threat, Expert Warns Against Alarmism

Professor in Infectious Diseases Rim Abdelmalek has stated that the Hanta virus does not pose a global pandemic threat and should not cause alarmism. She called for a rational reading of the health situation, emphasizing that the virus is not new and has been identified since the 1930s.

Virus Presence and Transmission

The Hanta virus is primarily present in Asia, the Americas, and certain regions of Europe. No local cases have been reported in Tunisia or most African countries. The virus's natural reservoir is rodents, and transmission to humans occurs mainly through inhalation of contaminated particles from their feces or saliva, particularly in enclosed or poorly ventilated spaces. However, human-to-human transmission is extremely rare and limited to exceptional situations.

Symptoms and Complications

The professor noted that symptoms vary depending on the strain and geographic region. Some forms can cause symptoms similar to the flu, while others can lead to severe complications affecting the kidneys, respiratory system, or heart. Strains present in Asia are often associated with hemorrhagic renal syndrome, while those in South America can cause severe respiratory syndromes.

Vulnerable Populations and Incubation Period

Rim Abdelmalek emphasized that the most severe forms primarily affect older individuals or those with chronic diseases, who are more vulnerable to complications. The incubation period can last several weeks, justifying medical surveillance for contacts.

Virus Characteristics and Response

The Hanta virus is not an emerging agent, known to the scientific community for decades, with an estimated 100,000 to 150,000 cases worldwide annually, without any evolution towards a global pandemic. There is no specific antiviral treatment or vaccine available. Treatment focuses on symptomatic care, including fever management, respiratory support, and complication treatment.

Conclusion and Call to Action

The professor concluded by urging against misinformation and over-mediatization of the issue, highlighting that current healthcare protocols are standard prevention measures, as the virus does not possess the necessary characteristics to cause a global health crisis.
