Health authorities in Pakistan’s southern Sindh province have confirmed a cluster of monkeypox cases among newborns in the northwest Khairpur district, sparking an immediate public health response and the temporary closure of critical care facilities. The outbreak, which has focused on the most vulnerable patients in neonatal wards, has prompted the provincial government to launch intensive contact tracing and review hospital hygiene protocols.
The Sindh Health Department first received alerts on March 14, when medical staff observed unusual skin symptoms in several infants. Following a series of laboratory tests, the infections were confirmed as monkeypox, a viral zoonotic disease that has seen varying levels of global resurgence in recent years. While the department has stated that the situation is currently under control, the discovery of the virus in a neonatal setting has raised concerns regarding nosocomial transmission—the spread of infection within a healthcare environment.
In a direct effort to contain the spread and identify the index case, authorities have temporarily closed neonatal intensive care units (NICUs) at one public and one private hospital in the region. This move is intended to prevent further transmission to other newborns and to allow for a comprehensive environmental cleaning and audit of infection control measures.
Understanding the Clinical Impact on Neonates
As a physician, it is important to clarify the distinction between infection and primary cause of death in neonatal cases. The Sindh Health Department conducted an expert review of the fatalities associated with this cluster and determined that some newborns who died were not directly killed by the monkeypox virus. Instead, these infants were premature and already battling severe health complications, which made them more susceptible to secondary infections and less able to recover from the viral stress.
Mpox, as it is now commonly referred to by the World Health Organization, typically presents as a rash that looks like pimples or blisters, accompanied by fever, headache and swollen lymph nodes. In newborns, whose immune systems are underdeveloped, the virus can be particularly aggressive, and the skin lesions can lead to secondary bacterial infections or systemic complications if not managed in a sterile environment.
The transmission of monkeypox in a NICU setting typically occurs through close physical contact with an infected person or contaminated materials, such as bedding, clothing, or medical equipment. Due to the fact that newborns are entirely dependent on caregivers, any breach in strict hand-hygiene or sterilization protocols can lead to rapid spread among patients who are already clinically fragile.
Timeline of the Khairpur Outbreak
The response in the Khairpur district followed a specific sequence of events as health officials attempted to isolate the source of the virus:
- March 14: Initial alerts are raised after infants exhibit unusual cutaneous (skin) symptoms.
- Mid-March: Laboratory samples are collected and processed, confirming the presence of the monkeypox virus.
- Late March/Early April: An expert review committee analyzes neonatal deaths, attributing them to prematurity and comorbidities rather than the virus alone.
- April 5: Official confirmation of the cases is released, and the closure of two NICUs is implemented to facilitate contact tracing.
Public Health Response and Containment Strategies
The current priority for the Sindh Health Department is the identification of the index case—the first person to introduce the virus into the hospital environment. This is critical because identifying whether the virus was brought in by a staff member, a visiting parent, or a patient allows authorities to close the gap in their infection control protocols.
Hospitals across the province have been directed to enforce rigorous infection control measures. According to standard guidelines from the Centers for Disease Control and Prevention, these measures typically include:
- Strict Isolation: Placing confirmed and suspected cases in single rooms with dedicated equipment.
- Enhanced PPE: Requiring healthcare workers to use gloves, gowns, and masks when treating suspected cases.
- Environmental Decontamination: Using hospital-grade disinfectants on all surfaces in the NICU to eliminate viral remnants.
- Staff Screening: Monitoring healthcare providers for any signs of rash or fever to prevent them from becoming vectors of transmission.
Contact tracing is currently ongoing to determine if the virus has spread beyond the hospital walls into the wider community. While the risk to the general public remains low, the Sindh Health Department has urged parents and caregivers to seek immediate medical attention if they notice any unusual rashes or flu-like symptoms in their children.
Risk Factors in Neonatal Care
| Risk Factor | Impact on Newborns | Mitigation Strategy |
|---|---|---|
| Immature Immunity | Higher susceptibility to systemic viral spread. | Prophylactic care and strict isolation. |
| Skin Fragility | Easier penetration of the virus through skin barriers. | Sterile handling and minimal invasive touch. |
| High-Touch Environment | Frequent contact with multiple caregivers and equipment. | Mandatory hand-hygiene audits. |
| Prematurity | Reduced respiratory and organ resilience. | Integrated supportive care and ventilation. |
What In other words for Public Health in Sindh
This incident highlights the critical importance of maintaining high biosafety standards in public and private healthcare facilities. The fact that both a public and a private hospital were affected suggests a potential systemic vulnerability in how zoonotic or emerging infectious diseases are screened before patients or visitors enter high-risk wards.
For the residents of Khairpur and the broader Sindh province, the situation serves as a reminder that monkeypox is not exclusively a global phenomenon but a local health concern that requires vigilance. The focus now shifts to the restoration of NICU services, which are essential for infant survival, once the health department is satisfied that the environment is sterile and the source of infection has been neutralized.

The Sindh Health Department is expected to provide a follow-up report once the contact tracing process is complete and the index case is identified. Further updates regarding the reopening of the affected NICUs will depend on the results of the final environmental screenings.
