However, the flu can lead to complications, such as pneumonia and even death.
What may seem like a cold, could be the flu. Be aware of these differences:. Most common colds are diagnosed based on reported symptoms. However, cold symptoms may be similar to certain bacterial infections, allergies, and other medical conditions. Currently, there is no medicine available to cure or shorten the duration of the common cold. However, the following are some treatments that may help to relieve some symptoms of the cold:.
Over-the-counter antihistamines medicine that helps dry up nasal secretions and suppress coughing. Because colds are caused by viruses, antibiotics don't work. Antibiotics are only effective when given to treat bacterial infections. Do not give aspirin to a child who has fever. Aspirin, when given as treatment for viral illnesses in children, has been associated with Reye syndrome.
This is a potentially serious or deadly disorder in children. Colds can lead to secondary infections, including bacterial, middle ear, and sinus infections that may require treatment with antibiotics. If you have a cold along with high fever, sinus pain, significantly swollen glands, or a mucus-producing cough, see your healthcare provider. So, when Covid rates are high, the chances of a runny nose being due to the virus are also high. The study also stresses that when Covid rates are low, a runny nose is less likely to indicate the sufferer has caught the coronavirus and is more likely to be due to a cold or even an allergy.
It concludes that while many people with Covid may report a runny nose, it is difficult to call it a definitive symptom as it is so common, especially during winter. The ZOE study found sneezing more than usual can be a sign of Covid in people who have been vaccinated, although it stresses sneezing is much more likely to be a sign of a cold or an allergy.
Many people with Covid have reported via the ZOE app that they have a sore throat that feels similar to one you might experience you get when you have a cold or laryngitis. Covid-related sore throats tend to be mild and last no more than five days so a very painful one that lasts longer is likely to be something else. If it persists, you should contact your GP.
Although it can be a Covid symptom, most people with a sore throat will probably just have a cold. While people who have Covid might not lose their sense of smell completely, it may change, so you may not be able to smell strongly-scented things, and your sense of taste may be affected too, so food may taste different or seem tasteless. A persistent cough is widely agreed to be one of the three main symptoms of Covid but, according to the ZOE study, only around four in 10 people who are ill with the virus will experience this.
A Covid cough is usually a dry cough, compared with a chesty one that brings up phlegm or mucus and that may indicate a bacterial infection. A persistent cough tends to arrive around a few days into the illness and usually lasts for around four or five days. If you have only had one dose of the vaccine, the ZOE study found the top symptoms were similar to those of people who were double-jabbed, but a cough was also common.
And for those who were unvaccinated, symptoms were also similar, with the addition of fever and a cough. If you have any of the symptoms, you should self-isolate at home and get a PCR Covid test as soon as possible. They present so similarly that only PCR testing can differentiate between the two.
Lateral flow testing can help with screening, but if someone has symptoms, they should go for a PCR swab test. Trying to self-diagnose is a sure fire way to send Covid case rates soaring again. The final collection, including the previously published sequences, consisted of full-length human rhinoviruses genomes. The researchers compared all the sequences to determine how they are related. Based on these relationships, they discovered that there may be up to 4 different species of rhinovirus.
The researchers found that all the virus RNA strands feature a cloverleaf-like shape at one end. Nearly every virus had a unique sequence in a section of this region. Analogous regions in related viruses have been shown to affect how pathogenic the viruses are. The researchers believe this stretch of sequence might play a similar role in rhinoviruses. The scientists also found evidence for distantly related strains swapping sections of RNA. Exactly where and how the viruses exchange genetic material in the body is uncertain, but multiple rhinoviruses are known to infect people simultaneously.
