5G Health and COVID Claims
Introduction
In the early months of 2020, as the SARS-CoV-2 pandemic spread worldwide, a distinct conspiracy theory gained traction across social media: that fifth-generation wireless telecommunications networks (5G) were either causing or amplifying COVID-19, or were themselves the source of illness being misattributed to the virus. The claim drew on pre-existing 5G health anxiety, anti-vaccination sentiment, and general distrust of government and technology corporations. Its consequences were immediate and material: cell towers were set ablaze in the United Kingdom, the Netherlands, Belgium, Sweden, and Ireland, and telecom engineers were physically attacked while attempting repairs.
The 5G-COVID theory is distinct from — though overlapping with — broader "5G radiation health" concerns, which focus on alleged long-term health effects from electromagnetic fields (EMF). This article focuses specifically on the claim that 5G caused or drives COVID-19 illness.
Core Claims
- 5G radio frequency (RF) radiation weakens the immune system, making people susceptible to COVID-19.
- 5G directly causes COVID-19 symptoms by damaging lung tissue or oxidising blood cells.
- Coronavirus outbreaks correlate geographically with 5G rollout areas.
- The COVID-19 pandemic is a cover story for harmful effects of 5G deployment.
- The virus was engineered to justify 5G infrastructure expansion.
The Physics: Why 5G Cannot Cause Viral Disease
The foundational claim is biologically incoherent because of what radio frequency radiation can and cannot do at a physical level.
5G uses non-ionising radiation. The electromagnetic spectrum divides broadly into ionising radiation (above approximately 10 eV photon energy: gamma rays, X-rays, extreme ultraviolet) and non-ionising radiation (below this threshold: ultraviolet-A, visible light, infrared, microwave, and radio frequencies). Ionising radiation carries sufficient energy per photon to break molecular bonds, damage DNA, and disrupt cellular chemistry. Non-ionising radiation lacks this energy. 5G frequencies — predominantly mid-band frequencies around 3.5 GHz in most countries, with some mmWave deployment at 24–100 GHz — are well within the non-ionising range. The photon energy at 3.5 GHz is approximately 14 microelectronvolts, orders of magnitude below the threshold for breaking any biologically significant chemical bond.
Radio frequency radiation cannot generate or transmit viruses. SARS-CoV-2 is a biological entity: a ribonucleic acid genome packaged in a protein coat, approximately 100–120 nanometres in diameter. It propagates through respiratory droplets and aerosols expelled by infected hosts. No electromagnetic field has the physical capacity to create, transmit, or activate a RNA virus. The proposal confuses a physical wave phenomenon (RF radiation) with a biological agent (a virus), mixing two entirely different causal frameworks.
Countries without 5G had COVID-19 outbreaks. Iran, which had no commercial 5G network when its severe COVID-19 outbreak began in February 2020, was among the earliest and hardest-hit countries. Multiple sub-Saharan African nations without 5G infrastructure reported COVID-19 outbreaks. Conversely, some areas with 5G rollout had lower COVID-19 incidence than adjacent areas without 5G. The geographic correlation claimed by proponents does not hold under scrutiny.
The "correlation" between 5G and COVID outbreaks is explained by population density. Both 5G networks and early COVID-19 outbreaks were concentrated in dense urban centres — London, New York, Madrid, Milan. Dense cities install new infrastructure first and also have higher transmission rates for respiratory pathogens. This shared urban correlation is not evidence of causation; it reflects a common confounding variable.
Thermal effects are the only established non-ionising biological mechanism, and they are below threshold at 5G intensities. Non-ionising RF radiation at sufficient intensity can produce thermal heating of tissue. This is the basis of microwave cooking and diathermy medical devices. International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines and national standards limit 5G exposure to intensities far below any level demonstrated to cause thermal tissue damage. Numerous independent reviews — including the 2020 ICNIRP guidelines update and the WHO's 2020 EMF health assessment — have found no established non-thermal biological effects of RF radiation at exposure levels within guidelines.
The 2020 Evidence Base
Scientific and public health organisations moved quickly to rebut the 5G-COVID claim directly. WHO published an explicit myth-busting statement in April 2020. Full Fact, Reuters Fact Check, Health Feedback, AP, and IFCN member organisations all published debunks. The UK's OFCOM and the British government's chief scientific adviser addressed the tower-burning directly.
A systematic review of the wider 5G health literature by the WHO Environmental Health Criteria programme noted no established adverse health effects from RF EMF below guideline levels, a conclusion consistent across multiple independent expert review bodies (ICNIRP, Scientific Committee on Health, Environmental and Emerging Risks, IEEE).
The Harm Was Physical
Unlike many misinformation episodes where harm is statistical, the 5G-COVID theory produced documented physical harm:
- Over 90 arson attacks on cell towers and mast sites in the UK alone between April and May 2020 (OFCOM data).
- Multiple BT Openreach and independent engineers physically assaulted while conducting maintenance, some hospitalised.
- Similar incidents were documented in Belgium, Sweden, Finland, the Netherlands, Ireland, and New Zealand.
- The damage disrupted legitimate communications infrastructure — including emergency services connectivity — in the middle of a pandemic.
Social media platforms including Facebook, YouTube, and Twitter/X took steps to remove content linking 5G to COVID-19 after the arson incidents escalated; this represented one of the earliest large-scale content moderation actions explicitly targeting infrastructure-threatening health misinformation.
Scientific Consensus
WHO, CDC, FDA, ICNIRP, Public Health England, Health Canada, and every major EMF health authority have confirmed that 5G does not cause or contribute to COVID-19 and that 5G frequencies cannot generate, transmit, or activate any virus. The scientific consensus is not in dispute.
Takeaway
The 5G-COVID claim represents a collision of two independent misinformation streams — pre-existing electromagnetic health anxiety and COVID-19 origin conspiracy theories — into a single claim with no physical or biological foundation. Its harm was unusually direct: cell tower fires disrupted critical infrastructure during a pandemic. Understanding why non-ionising radiation cannot cause viral disease requires basic physics literacy that public health communicators have since worked to build into broader science education.
Media Amplification and Legal Consequences
The theory did not stay confined to fringe corners of the internet. On 13 April 2020, ITV's This Morning aired a segment in which co-host Eamonn Holmes pushed back on a colleague's dismissal of the 5G-coronavirus link, telling viewers "it's very easy to say it is not true because it suits the state narrative." The remarks drew 419 complaints to UK media regulator Ofcom, which opened an assessment of the broadcast "as a priority." Holmes issued an on-air clarification the following day, stating there was "no scientific evidence to substantiate any of those 5G theories."
A separate viral video, posted to YouTube in March 2020 by California physician Thomas Cowan, claimed that electromagnetic fields, not a virus, were the true cause of the illness being called COVID-19. Actors Woody Harrelson and John Cusack shared the clip with their followers before YouTube removed it under its misinformation policy. Cowan closed his San Francisco practice and, in December 2020, surrendered his California medical licence; the state board's record also cited a prior, unrelated five-year probation imposed on him in 2017.
Criminal prosecutions followed the wave of tower arson. Liverpool Crown Court sentenced Michael Whitty, 47, to three years in prison after he set fire to a phone mast in the Knowsley area of Merseyside in April 2020, in the belief it was transmitting signals linked to COVID-19. Vodafone confirmed the mast was in fact a standard 4G site with no 5G equipment installed. The judge described the attack as showing "a high degree of planning and premeditation."
Academic Analysis of the Conspiracy's Spread
A social network analysis published in the Journal of Medical Internet Research examined 233 tweets carrying the #5GCoronavirus hashtag between 27 March and 4 April 2020. It found that only 34.8% of tweets endorsed a link between 5G and COVID-19, while 32.2% actively denounced the claim and the remainder were neutral; the authors concluded that engagement from skeptics rebutting the theory, more than from believers, drove much of its visibility online. InfoWars was the most-shared external source among the tweets sampled, followed by YouTube, and a single dedicated activist account posted 303 times in the seven-day window. The researchers also noted a relative absence of authoritative voices actively countering the claim within the network at that early stage, a gap that health agencies and fact-checkers moved to close in the following weeks.
Evidence Filters10
Early COVID-19 outbreaks coincided with major 5G rollout cities
SupportingWeakWuhan, London, New York, and Milan — among the first cities with major COVID-19 outbreaks — were all in the process of deploying 5G networks in 2019–2020, a correlation widely cited on social media.
Rebuttal
The correlation is explained by population density and urban connectivity, not 5G. Dense cities install new telecommunications infrastructure first and are also the entry points for new respiratory pathogens due to international travel and high contact rates. Countries without any 5G deployment — Iran, multiple sub-Saharan African nations — experienced severe COVID-19 outbreaks contemporaneously. The correlation disappears when population density is controlled for.
Some scientists have raised concerns about 5G and EMF health effects
SupportingWeakThe 5G Appeal, signed by hundreds of scientists, calls for a moratorium on 5G deployment pending more research into potential health effects of electromagnetic fields.
Rebuttal
The 5G Appeal concerns potential long-term EMF health effects at the cellular level — a separate and ongoing scientific debate. None of the signatories claim that 5G causes viral disease or COVID-19. The Appeal does not represent mainstream scientific consensus; ICNIRP, WHO, and national health bodies have reviewed the evidence and not found grounds for a moratorium. Citing the Appeal as support for the 5G-COVID claim conflates two distinct issues.
Higher-frequency mmWave 5G can interact with biological tissue
SupportingWeakMillimetre-wave frequencies (24–100 GHz) used in some 5G deployments are absorbed in the outer layers of skin and the cornea rather than penetrating deep tissue, unlike lower-frequency RF. Some researchers study potential effects at these frequencies.
Rebuttal
Superficial absorption does not mean biological harm occurs. ICNIRP and WHO have reviewed mmWave health effects; established adverse effects occur only at intensities far exceeding deployment levels. No study has found that mmWave 5G damages the immune system or promotes viral susceptibility. The vast majority of deployed 5G uses mid-band frequencies (3.5 GHz), not mmWave, further limiting even this speculative mechanism.
Cell towers were attacked across multiple countries following the claim
SupportingWeakOver 90 arson attacks on cell towers were documented in the UK alone in spring 2020, with similar incidents in Belgium, Netherlands, Sweden, Ireland, and New Zealand, indicating widespread public uptake of the claim.
Rebuttal
The spread of a belief, even to the point of physical violence, is not evidence of its truth. Public uptake reflects successful misinformation propagation, not scientific validity. Every major public health and telecommunications authority rebutted the claim. The attacks damaged legitimate infrastructure including emergency services communications.
Wuhan was among China's first 5G pilot cities, launched in late 2019
SupportingWeakChina launched a 5G pilot in Wuhan in November 2019, the same month that retrospective analysis suggests early SARS-CoV-2 transmission was occurring, which proponents framed as suspicious timing.
Rebuttal
Wuhan is China's seventh-largest city and a major transportation hub — both reasons it would be an early 5G test city and an early site of outbreak. The "suspicious timing" framing ignores that dozens of Chinese cities launched 5G pilots contemporaneously; not all experienced the earliest COVID-19 cases. Coincident timing between unrelated events is not causation, particularly when no physical mechanism connecting the events exists.
Some videos appeared to show birds falling from the sky near 5G installations
SupportingWeakViral videos in 2019–2020 alleged to show mass bird deaths near 5G masts circulated widely, with claims that RF radiation was killing wildlife.
Rebuttal
The bird death videos were debunked by multiple fact-checkers: the most widely shared footage was from a Dutch municipal pest control operation involving starlings, unrelated to 5G. Electromagnetic fields from broadcast towers at regulated exposure levels have not been shown to cause mass bird mortality. The video evidence was fabricated or miscontextualised.

Frequently Asked Questions
Can 5G cause COVID-19?
No. 5G is a radio frequency telecommunications technology; SARS-CoV-2 is a biological virus spread through respiratory droplets. Radio waves cannot generate, transmit, or activate any virus. The physical mechanism proposed is impossible: non-ionising RF radiation lacks the energy to affect biological molecules in the way required. Countries without any 5G had major COVID-19 outbreaks.
Does 5G weaken the immune system?
No established evidence exists that 5G RF radiation at guideline exposure levels weakens the immune system. Multiple independent reviews — including the 2020 ICNIRP guideline update and WHO EMF assessments — have found no established adverse health effects from RF radiation below international guidelines. Immune-weakening claims cite speculative research at doses far exceeding deployed levels.
Why were cell towers attacked if the claim was false?
The spread of a misinformation belief to the point of physical violence reflects successful misinformation propagation, not scientific validity. The arson attacks — over 90 in the UK alone in spring 2020 — damaged critical communications infrastructure during a pandemic, including emergency services connectivity, demonstrating the real-world harms of false health claims.
Are there any legitimate health concerns about 5G?
The 5G Appeal, signed by hundreds of scientists, calls for more research on potential long-term health effects of RF EMF more broadly. This is a separate debate from the 5G-COVID claim. ICNIRP and WHO have reviewed available research and not found grounds for health concern at guideline exposure levels, but the scientific community continues to monitor new evidence.
What type of radiation is 5G?
5G uses radio frequency electromagnetic radiation, which is non-ionising — meaning its photons lack sufficient energy to break chemical bonds, damage DNA, or disrupt cellular chemistry. This is the same category as FM radio, WiFi, and 4G. Ionising radiation (X-rays, gamma rays) does carry sufficient energy to damage biological molecules; 5G is not in this category.
