Where You Live Determines Your Risk: How Uneven COVID-19 Infection Patterns Reveal Disparities in Health Care Systems Across Lebanon

Where You Live Determines Your Risk: How Uneven COVID-19 Infection Patterns Reveal Disparities in Health Care Systems Across Lebanon

The Healthcare Scene in Lebanon
Rami spent the majority of his life in Aley, Choueifat El Aamrousiyeh, a quiet town where people know each other all throughout the area. When Covid-19 began spreading in Lebanon, he assumed that his location would be relatively safe in terms of health implications. After all, the news was primarily focused on Beirut.

During peak months, Rami started hearing about his neighbors testing positive at a pace he certainly did not expect. Meanwhile, his cousin Leila, who lives close by in Kahhaleh, hardly knew anyone infected. They were both in the same region, but faced entirely different risks.

Rami’s worry and stress levels grew a lot, especially for his elderly parents with chronic conditions. If Covid spread in his town at a fast pace, would they be able to get help in time? Would testing and vaccination centers be available in close proximity to where they live? Would nearby hospitals be overwhelmed with full capacities?  

Leila and Rami’s experiences reflect what many Lebanese families endure. Two households in the same region, but different towns, had completely different stress levels regarding the readiness of healthcare emergency responses. 

Health Patterns in Lebanon: What the Data Reveals
We tend to think of public health at the regional level, but covid behaved more so at a town level per region. This exposed imbalances that are not usually explored. Top town per region with the highest contribution to the total national case count revealed unexpected results:

  • In Aley (region), Choueifat Aamrousiyeh alone accounted for 2.75% of all cases in the country.
  • In Baalbek-Hermel, Baalbek alone stood out with 1.33%, which is much higher than surrounding towns
  • The remaining regions showed similar patterns: one or two towns carried the majority of cases

What Does This Mean Exactly?
People like Rami, who happen to live in a high risk town, experienced a completely different pandemic from people in towns just a few kilometers away. This is likely to repeat in the future if another major healthcare crisis hits the country.

Moving Forward, What Can Be Done?

  1. Prioritize hotspot towns: testing centers, clinics, and awareness campaigns should start where case data shows concentration, not where population is highest.
  2. Build local readiness plans: Instead of generic region level plans, towns with higher infection percentages need specific preparation steps (rapid testing, temporary isolation centers, and community awareness). 
  3. Use data driven action plans: Covid case percentages help identify where outbreaks are likely to happen again. If regions plan smarter, hospitals and clinics face less chaos.
  4. Strengthen communication and public awareness: Towns with consistently high rates should receive ongoing health messaging to prevent repeat scenarios.

The Key Takeaway
By understanding how Covid-19 was not distributed proportionately across towns, we can finally design smarter, more effective responses. This applies not only to pandemic/epidemics, but to any future public health threat in Lebanon.

Unmuting Mount Lebanon’s Emergency: Understanding how Silent Diseases lead to Sudden Deaths

Unmuting Mount Lebanon’s Emergency: Understanding how Silent Diseases lead to Sudden Deaths

During the peak of the COVID-19 pandemic back in 2021, waking up to news of people passing away due to symptoms complications became the norm, but in the midst of the overwhelming news, one man’s story hit us hard. His name was Nader, a 46-year-old from Baabda, a man known for his loud laugh, strong coffee, and long Friday lunches with friends. We knew him as the “office guy”; he was in fact there for everyone, until the day when his lungs failed him. He caught COVID, the symptoms escalated quickly. Within days, his oxygen levels dropped, and despite being admitted to the hospital, the virus was already overpowering a weak cardiovascular system. Everyone was in shock, since Nader was just in his mid-40s, and we expected he’d beat the virus easily. But once the doctors informed us he didn’t make due to his overworked cardiovascular system, we understood it was beyond COVID-19, and not only Nader’s lungs have failed him, but a whole lifestyle and healthcare system.

This raised a bigger question for us: Which areas in Lebanon have unusually high levels of chronic disease that make its residents more at risk during crises? To explore this, we analyzed health data across governorates, focusing on cardiovascular disease (CVD) and hypertension (HTN). We first explored how the percentage of COVID-19 cases out of national totals was distributed, with Mount Lebanon leading in this area.

To understand further the extent of the health risk, we compared these chronic disease patterns to COVID cases in all Lebanese Governorates. What we saw flagged Mount Lebanon as a hight risk Governorate as it has the regions with the highest burden of CVD and HTN also recorded the highest COVID cases. This means that in these areas, the symptoms of COVID-19 will be exacerbated by the existing chronic disease, which leads to more complicates and higher hospitalization rates.

The highest-risk governorate being Mount Lebanon isn’t only about pandemic response. It’s about addressing the silent epidemic of chronic disease that makes future health crises even more dangerous. Based on our analysis, we believe it’s time to expand early screening programs, increase community-level hypertension detection, and strengthen preventive care. Preventative measures are needed so that the most vulnerable groups are able to cope with unprecedented health emergencies. If we focus on prevention now, we can reduce risk and help ensure that stories like Nader’s don’t repeat themselves.
