Ebola Virus Alert: Understanding Risks, Transmission & Professional Prevention Advice

As Ebola outbreaks resurge across parts of Africa, Hong Kong has tightened inbound health screenings for travellers from affected areas, drawing public attention to this highly lethal virus.

Ebola spreads not only through direct contact, but poor environmental conditions and inadequate hygiene also heighten infection risks, making proper environmental management essential for effective disease prevention.

This article breaks down key facts about Ebola and shares practical professional measures to help you lower potential infection hazards.

What is Ebola Virus?

Ebola virus is a highly fatal zoonotic virus first discovered in Africa back in 1976, with a fatality rate between 50% and 90%. To date, there are no widely accessible specific vaccines or targeted treatments for general use.

Ranked among pathogens with the highest biosafety classification, Ebola is extremely sensitive to environmental and hygiene conditions. Effective prevention relies on a combination of personal protection practices and professional environmental management solutions.

How the Virus Spreads? 

Ebola virus is primarily transmitted via direct contact.

• People may get infected by coming into contact with blood and bodily fluids such as saliva, vomit and faeces from infected individuals or virus-carrying wild animals, as well as contaminated surfaces including door handles, tables and clothing.
• Indirect infection risks also exist when people touch environments contaminated with secretions and excreta from virus hosts such as fruit bats.

It is important to note that Ebola cannot spread through daily respiratory droplets, airborne transmission or insect bites. While there is no need for excessive panic, hidden risks brought by contact with contaminated surroundings should never be overlooked.

Infection Symptoms 

The incubation period of Ebola virus ranges from 2 to 21 days. In this period, infected persons usually show no symptoms and are not contagious to others.

• Common early symptoms include: Sudden fever, fatigue, muscle pain, headache and sore throat
• As the condition worsens, patients may suffer from vomiting, diarrhoea and skin rashes.
• In severe cases, both internal and external bleeding as well as multiple organ failure may occur.

Anyone who develops the above symptoms after travelling to affected regions or having suspected exposure should seek medical attention immediately and disclose their travel and contact history for timely screening and treatment.

How to Minimise Ebola Transmission and Infection Risks

Individuals and commercial establishments alike can adopt the below measures to mitigate the spread and infection risks of Ebola virus. 

Personal Preventive Measures

• Refrain from approaching unknown wild animals. Never touch or collect animal carcasses, and stay away from messy areas that serve as habitats for wild species.
• After returning to Hong Kong from Ebola-affected areas in Africa, keep close track of your health condition for one full month. Seek immediate medical assistance and disclose your travel history once you develop fever, fatigue or other abnormal symptoms.
• Practise good hand hygiene daily, and regularly sanitise frequently touched surfaces including mobile phones and door handles to reduce indirect exposure risks.

Workplace & Organisational Prevention Guidelines

• Strengthen employee health management. Encourage staff with travel history to high-risk zones to make voluntary declarations, and arrange necessary health monitoring support.
• Arrange regular cleaning and professional disinfection for communal areas, workspaces and all high-contact points, so as to eliminate potential residual virus threats in the environment.
• Uphold proper premises hygiene standards. Clear away piled waste and damp corners in a timely manner to discourage wild animals from gathering, and effectively lower the risk of environmental contamination.

Professional Pest Disinfection: Key to Stopping Environmental Transmission

Indirect Ebola infection risks are closely linked to overall environmental hygiene standards.

Poorly maintained and cluttered premises tend to attract wild animals. Their secretions and excreta may contaminate surrounding surfaces, creating hidden risks of disease transmission.

Rentokil’s professional pest disinfection service is specially developed to tackle such hazards:

We apply specialised biocidal solutions in spray form across pest-active zones, combined with ultra-low volume (ULV) disinfection technology. This method reaches hard-to-clean crevices and corners, effectively reducing disease-causing microbes left by pests and cutting down environment-related infection risks.

Our service works efficiently against common bacteria and viruses. All applied solutions are food-safe, non-corrosive and stain-free, suitable for use on soft metals, plastics, fabrics and most other surfaces. It delivers long-lasting protection against threats posed by bacteria, viruses, mould and other harmful microorganisms.

With our integrated pest management and professional disinfection solutions, we help eliminate factors that draw wild animals close to your premises. We also carry out targeted treatment on potentially contaminated areas, effectively breaking the chain of indirect disease transmission.
