1. Anosmia (loss of smell) is a symptom. The most commonly reported symptoms of COVID-19 include fever, cough and shortness of breath. However, as the disease has spread around the world, healthcare providers have noticed a few unusual symptoms, including loss of smell (anosmia) and decreased sense of taste (ageusia).
In South Korea, 30% of people who tested positive for the virus said that loss of smell was their first major symptom. In Germany, more than 2 out of 3 confirmed cases included loss of smell and taste.
2. Coronavirus can make babies seriously ill. Compared to adults, children appear much less likely to get sick if they contract the novel coronavirus. However, a report from China suggests that the very young may be more vulnerable to serious illness than older children. Researchers reviewed the records of 2,143 Chinese children and found that nearly 11% of sick infants were seriously or critically ill, compared to 7% of children ages 1 to 5 years, 4% of children ages 6 to 15 and 3% of teenagers aged 16 and older. In the United States, from February 12 to April 2, less than 2% of cases were in children younger than 18 years.
A multisystem inflammatory syndrome (MIS) is affecting some children positive for the current-CoV-2 infection. MIS is rare but very serious.
3. The COVID-19 virus can live on surfaces for days. COVID-19 is spread primarily through respiratory droplets. When an infected person sneezes or coughs, the virus can travel from one person to another, either directly or indirectly.
Researchers have found that the virus can live up to 24 hours on cardboard and 2 to 3 days on plastic and stainless steel.
4. People who don’t have symptoms can spread the virus. One-third of 565 Japanese citizens who were evacuated from Wuhan, China in February that tested positive for coronavirus infection never developed COVID-19 symptoms; and a study out of China reports more than half of infected children had no symptoms or only mild symptoms.
5. People with type A blood may be more susceptible to infection. A Chinese study of 2,173 individuals who were hospitalized with COVID-19 found that the proportion of sick people with type A blood was significantly greater than researchers would expect based upon the percentage of people with type A blood in the general population. The study also found that there were fewer sick people with type O blood than would be expected.
6. Reinfection may be possible. If a person gets COVID-19, are they immune to future infection but how long will immunity last? Ten to 30% of our common colds are caused by four different coronaviruses, and we all know that having a cold doesn’t keep you from catching another cold. But animal research suggests the novel coronavirus may be different: Macaque monkeys who were exposed to SARS-CoV-2 after recovering from COVID-19 did not develop another infection.
