Dr Abdul Mannan Baig

MBBS, PhD

Medical doctor and scientist in COVID-19 and long COVID. Board Member, Vitalis Foundation.

  • Long COVID
  • Neuro-COVID
  • Drug repurposing
  • Neuroinvasive infections

Dr Abdul Mannan Baig is a medical doctor and scientist whose work sits where infection meets the nervous system. He was among the first researchers in the world to argue, in early 2020, that SARS-CoV-2 can reach and damage the brain, and one of the earliest to push for long COVID to be recognised as a distinct chronic illness.

Today his research centres on long COVID: what drives it, how to diagnose it and how to treat it. He joined the Vitalis Foundation board in South Australia in 2026.

His contribution to COVID-19 and long COVID science

2020

Showing that COVID-19 can affect the brain

Weeks into the pandemic, Dr Baig and colleagues published Evidence of the COVID-19 Virus Targeting the CNS in ACS Chemical Neuroscience. It mapped where the virus's entry receptor, ACE2, is found in nervous tissue, proposed routes by which the virus could reach the brain (including through the nose), and called for COVID-19 to be staged by how far it affects the nervous system. The University of Sunderland credits it as the first paper to flag loss of smell and taste as significant COVID-19 symptoms. It has been cited more than 3,100 times.

2020

Naming long COVID as a chronic illness

He proposed the term Chronic COVID Syndrome for patients who stay unwell long after infection, and set out how the virus's effects on the brain could explain their lasting symptoms. These papers have been cited more than 550 times.

2021–2024

Invited by leading journals

Nature Reviews Neurology commissioned him to write on the neurological cost of COVID-19. In 2024 he co-authored a Lancet Neurology paper making the case that SARS-CoV-2 infection is a cause of neurodegeneration.

Today

Causes and treatments of long COVID

His recent work covers how long COVID develops and how it can be diagnosed and treated, the role of autoantibodies against the body's own nerve-signalling receptors, the virus's effects on the immune system (including lymphopenia and autoimmunity), and delivering treatment through the nose to reach the brain. He is a regular speaker at international long COVID conferences, including the Long Covid Coalition Congress.

Beyond COVID-19: brain infections, drug repurposing, cancer and brain injury

Before COVID-19, Dr Baig specialised in microbes that invade the brain, including the "brain-eating" amoebae Naegleria fowleri and Acanthamoeba, which cause rare but often fatal infections. He used computational biology, protein modelling and drug-docking methods to find weak points in these organisms, and tested existing approved medicines against them. Over eight years he published more than 55 papers in this field. That grounding in neuroinvasive infection, and in repurposing existing drugs, is what he brought to COVID-19 from its first weeks.

The same drug-target approach runs through his other work. In cancer, he has studied muscarinic M1 receptors in prostate cancer and searched for conserved protein targets in androgen-independent prostate cancer cells. In traumatic brain injury, he has co-authored studies of new thalidomide-like anti-inflammatory drugs that reduced inflammation and brain injury (2022, 2023 and 2025).
