Muscle twitching, known as myoclonus, is an uncontrollable, fast, and sudden muscle movement that can be harmless or a symptom of a medical condition. While viruses are known to cause muscle pain, weakness, and inflammation (myositis), there is limited medical information on viruses triggering muscle twitching. However, some people have reported experiencing muscle twitching after viral infections, such as influenza, COVID-19, shingles, and the common cold. In rare cases, viral myositis can lead to complications like rhabdomyolysis, which can cause permanent kidney damage.

Myoclonus: an uncontrollable, sudden muscle movement, which can be harmless or a symptom of a nervous system condition
Myoclonus is characterised as an uncontrollable, sudden muscle movement, which can be brief and resemble a twitch, jerk or spasm. This condition can be harmless and occur for normal reasons, or it could be a symptom of a nervous system condition. Myoclonus can be inherited or indicate a lesion in your brain. It can also occur with or because of seizures, especially myoclonic seizures.
Myoclonus can be caused by a wide range of reasons, some of which are harmless and some of which are indicative of a more serious nervous system condition. Some harmless causes include hiccups, sleep myoclonus (hypnic jerks), and startle reflexes. These are normal unless they start to occur more frequently or persist for longer than usual. For example, hiccups are only a concern if they last for a couple of days or more. Sleep myoclonus refers to sudden sharp muscle movements that happen as you fall asleep or wake up, while startle reflexes are jump-like movements that occur when you are surprised or scared.
Myoclonus can also be indicative of a more serious nervous system condition. In some cases, it can be inherited, as with essential palatal myoclonus, or it can be a symptom of a lesion in the brain. Myoclonus can also occur in conjunction with seizures, particularly myoclonic seizures. In rare cases, myoclonus can be a symptom of acute viral myositis, which is associated with multiple viruses, including influenza, H1N1, and SARS-CoV-2.
While viral infections can cause myoclonus, they are not the only cause. Other potential causes include bacterial, fungal, or parasitic infections, as well as autoimmune conditions, drug side effects, and injury. In some cases, the cause of myoclonus may be unknown. If you are experiencing myoclonus, it is important to consult a healthcare professional for a proper diagnosis and treatment plan.

Myositis: inflammation in muscles, caused by viral infections, which can lead to muscle weakness and pain
Myositis refers to a group of conditions that cause inflammation of the muscles, leading to muscle weakness and pain. It is often the result of an autoimmune response, where the body attacks its own tissues, or it can be caused by infection, injury, or drug side effects. Viral infections are the most common infectious cause of myositis.
Viral myositis typically occurs during the recovery phase of an illness, with influenza being the most commonly implicated virus. Other viruses that can cause myositis include coxsackievirus, polyomaviruses such as BK and JC, parvovirus B19, adenovirus, varicella zoster virus, dengue, and coronaviruses such as SARS-CoV-2. Myositis caused by viral infections usually affects the calf muscles but can involve other muscle groups in about one-third of cases.
The symptoms of viral myositis include sudden onset of muscle weakness, pain, and tenderness. In some cases, patients may also experience fever, fatigue, and muscle stiffness, making it difficult to perform daily tasks. Diagnosis of myositis can be challenging, and proper diagnosis may take some time. Laboratory findings may show elevated levels of serum creatine kinase (CK).
Treatment for viral myositis typically focuses on managing symptoms, as the condition usually resolves within a week without specific treatment. However, in rare cases, myositis can lead to serious complications such as rhabdomyolysis, which can cause permanent kidney damage and requires hospitalization and immediate medical attention.
While twitching can be a symptom of myoclonus, which is an uncontrollable, sudden, and brief muscle movement, it is not specifically mentioned as a symptom of myositis. However, viral infections themselves have been linked to muscle twitching in some reports.

Polyomaviruses: small, double-stranded DNA viruses that cause mild respiratory symptoms and may lead to myositis
Myoclonus is an uncontrollable, fast, and brief muscle movement that can be compared to a twitch, jerk, or spasm. It can be caused by a wide range of factors, some of which are harmless, while others may be indicative of a more serious nervous system condition.
Myositis is a group of conditions that cause inflammation in the muscles, which can lead to weakness, swelling, and pain. While the exact causes of myositis are not always clear, it is believed to be triggered by infection, injury, autoimmune conditions, or drug side effects. Viral infections are the most common infectious cause of myositis, with the common cold, flu, and HIV being examples of viruses that can cause it.
Polyomaviruses are small, double-stranded DNA viruses that are widespread and often cause mild respiratory symptoms or are asymptomatic in humans. The two polyomaviruses most often associated with human disease are the BK and JC viruses. In one case, a patient on immunosuppression developed fatigue, myalgias, weakness, and loss of visual acuity, with a muscle biopsy of the biceps brachii revealing myositis and atrophy. While polyomaviruses typically cause mild symptoms, they have the potential to lead to more severe issues, such as myositis, in certain cases.
In addition to polyomaviruses, other viruses such as adenovirus, varicella zoster virus, and dengue have also been linked to myositis. Furthermore, during the H1N1 pandemic, several cases of acute myositis in adults following influenza-like illness were reported. These cases exhibited muscle weakness, pain, and tenderness during the recovery phase of the virus, with complete resolution typically occurring within a week.
While twitching can be a symptom of many conditions, there is also a correlation between viral infections and the onset of twitching. Several individuals have reported experiencing twitching after viral infections, including COVID-19, the flu, and shingles. Therefore, while not always the case, viruses can indeed be a potential trigger for muscle twitching in some individuals.

Adenovirus: associated with myocarditis, myositis, and rhabdomyolysis, which can cause muscle issues
Adenoviruses are a group of viruses that can cause mild to severe infections throughout the body. They commonly affect the respiratory system, causing symptoms similar to the common cold or flu. Adenovirus infections can also lead to gastrointestinal issues, such as gastroenteritis, resulting in stomach pain, diarrhea, nausea, and vomiting. In rare cases, adenoviruses can affect the nervous system, bladder, or urinary tract.
While adenoviruses typically cause respiratory and gastrointestinal symptoms, they have also been associated with more severe complications, including myocarditis, myositis, and rhabdomyolysis. Myocarditis is an inflammation of the heart muscle, while myositis refers to inflammation of the muscles. Rhabdomyolysis is a rare but potentially fatal syndrome resulting from the breakdown of skeletal muscle, leading to the release of muscle cell contents into the bloodstream. This release can cause renal tubular toxicity, acute renal failure, cardiac arrhythmia, and compartment syndrome.
Mishra and colleagues reported a case where a patient on immunosuppression developed fatigue, myalgias, weakness, and loss of visual acuity. Further investigations revealed myositis and muscle atrophy. Adenovirus has been implicated in similar cases of myocarditis, myositis, and rhabdomyolysis, indicating a possible link between the virus and these muscle-related conditions.
It is important to note that adenoviruses are highly contagious and can spread through close contact, respiratory droplets, or touching contaminated surfaces. While most infections are mild and self-limiting, severe cases can occur, especially in individuals with weakened immune systems or underlying respiratory or cardiac conditions. Currently, there is no specific treatment or vaccine available for the general public, but good hygiene practices and disinfectants are recommended to reduce the risk of infection and transmission.

Coronavirus: can invade muscle cells, causing myopathy and rhabdomyolysis, resulting in muscle problems
Myoclonus is an uncontrollable, fast, and brief muscle movement, often referred to as a twitch, jerk, or spasm. It can be caused by a wide range of reasons, including viruses. While many causes are harmless, myoclonus can also indicate a serious nervous system condition.
Viral infections are a common infectious cause of myositis, a group of conditions that cause inflammation in the muscles. Myositis can be caused by viruses directly attacking muscle tissue or by releasing substances that damage muscle fibers. Common viruses that can cause myositis include the common cold, flu, and HIV.
Coronaviruses, in particular, can cause skeletal muscle injury and myopathy due to their ability to invade muscle cells. Myopathy refers to diseases that affect skeletal muscles, resulting in muscle weakness and pain. Severe respiratory distress, systemic inflammatory response, and sepsis are major risk factors for myopathy caused by coronaviruses.
Furthermore, rhabdomyolysis, a rare but serious complication of myositis, has been associated with adenovirus, another type of virus. Rhabdomyolysis can lead to permanent kidney damage and requires hospitalization and treatment with intravenous fluids.
While the relationship between viruses and muscle twitching requires further exploration, anecdotal evidence suggests a correlation between viral infections, including COVID-19, and the onset of twitching. In some cases, muscle twitching has persisted for months after the initial viral infection.
