Indonesia’s Ministry of Health (Kemenkes) has implemented strict monitoring of passengers arriving from South America to prevent the potential introduction and spread of hantavirus. This heightened surveillance is a direct response to detected cases aboard the MV Hondius cruise ship, which previously sailed from Argentina to Cape Verde.
The health ministry is prioritizing travelers from Argentina and other nations within the South American region. To ensure no cases slip through the cracks, officials are leveraging the “All Indonesia” recording system to track travel histories. This system allows health authorities to identify high-risk passengers even if they have transited through other hubs, such as Singapore, before entering Indonesia.
Andi Saguni, the Acting Director General of Disease Control at the Ministry of Health, emphasized that the strategy is designed to be comprehensive. “Special attention is being given to passengers from South American countries, including Argentina and others in the region,” Saguni stated on Wednesday. He noted that the “All Indonesia” system can read data regarding a traveler’s country of origin regardless of their final transit point.
Understanding the Hantavirus Threat: HPS vs. HFRS
As a physician, it is important to clarify that “hantavirus” is not a single disease but a group of viruses that can cause two distinct and severe clinical syndromes. According to the Ministry of Health, these include Hantavirus Pulmonary Syndrome (HPS) and Hemorrhagic Fever with Renal Syndrome (HFRS).
The distinction between these two is critical for public health management. In Indonesia, the variant typically found is HFRS, which is derived from the Seoul strain. However, the cases associated with the MV Hondius cruise ship involve the Andes strain. A key difference between these strains is the mode of transmission. while the Andes strain has shown specific transmission patterns on the ship, the Ministry noted that transmission from rats to humans, as seen with the Andes strain, has not been previously observed with the local Seoul strain in Indonesia.
The potential severity of these conditions makes the current monitoring essential. HPS typically affects the lungs, leading to severe respiratory distress, while HFRS primarily targets the kidneys, causing hemorrhagic fever and renal failure.
The Case of the Close Contact
The Ministry of Health is currently managing a specific case involving a 60-year-old male foreign national, identified by the initials KE, who resides in Central Jakarta. KE was identified as a close contact of a victim on the MV Hondius. Specifically, he shared a flight from Saint Helena to Johannesburg with a 69-year-old woman who later died from the virus.
Health officials have expressed that the public does not need to worry regarding this specific case, as laboratory tests have confirmed that KE is negative for hantavirus. Despite the negative result, KE remains under observation due to his health profile. He is currently asymptomatic but presents with several comorbidities, including uncontrolled hypertension and a history of vaping (electronic cigarettes).
To ensure absolute safety, KE is currently being quarantined at the RSPI Sulianti Saroso, Indonesia’s premier infectious disease hospital.
Timeline of Risk and Monitoring
The Ministry’s approach is dictated by the biological window of the virus. The incubation period for Hantavirus Pulmonary Syndrome (HPS) is approximately 45 days. Because of this extended window, the Ministry of Health will maintain intensive monitoring for the duration of this period to ensure no late-onset symptoms appear in close contacts.
To provide a clearer picture of the current health protocol, the following table outlines the monitoring framework:
| Monitoring Phase | Duration | Primary Objective |
|---|---|---|
| Intensive Monitoring | Up to 45 Days | Detect HPS symptoms during the full incubation period. |
| Self-Isolation Window | 30 Days | Ensure passengers remain isolated until health checks are cleared. |
| Gradual Reduction | Post-30 Days | Scale back surveillance once all passengers are confirmed safe. |
Distinguishing the Current Crisis from COVID-19
Given the history of global health emergencies, Andi Saguni was careful to distinguish the current hantavirus situation from the COVID-19 pandemic. The Ministry of Health is operating under the goal that this event remains a limited cluster confined to the MV Hondius passengers, rather than evolving into a broader public health crisis.

The strategy for resolution is clear: once the 30-day self-isolation and monitoring period has passed and all relevant passengers have undergone health screenings and been cleared, the situation will be declared safe. At that point, the intensity of flight monitoring and surveillance will be reduced gradually.
For those traveling from South America or monitoring the situation, official updates can be found through the World Health Organization or the Indonesian Ministry of Health’s official communications.

The next critical checkpoint for health officials will be the conclusion of the 30-day isolation period for the remaining passengers of the MV Hondius cluster, which will determine when border surveillance can return to baseline levels.
